00:00:00.030 so you've been working on your air 00:00:01.55000:00:01.560 conditioner and you found the problem 00:00:03.05000:00:03.060 and the problem is the contactor is not 00:00:05.48000:00:05.490 pulling it but why why is it not pulling 00:00:08.03000:00:08.040 it stay tuned to find out 00:00:17.47000:00:17.480 [Music] 00:00:36.97000:00:36.980 hey guys Jay here with one advice to be 00:00:39.83000:00:39.840 on my how to fix your AC video the most 00:00:43.07000:00:43.080 frequently asked question on there or 00:00:44.99000:00:45.000 one of the most frequently asked is my 00:00:47.36000:00:47.370 contactor is not pulling in what could 00:00:49.40000:00:49.410 be causing that but before I get into 00:00:51.17000:00:51.180 the 10 reasons why this could be 00:00:52.61000:00:52.620 happening let's just quickly go over to 00:00:54.65000:00:54.660 contact her and how it works so right 00:00:56.39000:00:56.400 here we got our disconnect this is where 00:00:58.97000:00:58.980 your 240 volts comes from you know our 00:01:01.61000:01:01.620 circuit breaker panel is hooked up 00:01:03.71000:01:03.720 straight to this thing it gets too hot 00:01:05.51000:01:05.520 legs from here to 120 legs to get you to 00:01:08.09000:01:08.100 40 and that goes right into your AC unit 00:01:11.03000:01:11.040 through this whip and this whip will 00:01:12.83000:01:12.840 typically have three wires inside of it 00:01:14.87000:01:14.880 two hot legs on the ground and as you 00:01:17.45000:01:17.460 can see that goes straight up into my 00:01:19.04000:01:19.050 unit and also there's a thermostat wire 00:01:23.24000:01:23.250 a lot of times they'll come from the 00:01:24.85900:01:24.869 disconnect sometimes it'll come out with 00:01:26.78000:01:26.790 the refrigerant pipes once in a while 00:01:28.96900:01:28.979 it'll come out of the wall but that is 00:01:31.16000:01:31.170 also routed straight to your AC 00:01:33.46900:01:33.479 condenser unit so right here we got two 00:01:38.69000:01:38.700 hot legs coming in and I'll just show 00:01:41.21000:01:41.220 you quick with my meter the two hot legs 00:01:43.82000:01:43.830 they come in straight from the 00:01:45.05000:01:45.060 disconnect and into one side of the 00:01:47.48000:01:47.490 contactor so if I put the black and red 00:01:50.18000:01:50.190 wire right here they come from the 00:01:52.16000:01:52.170 disconnect if I put my two leads on the 00:01:54.89000:01:54.900 two screws here as you can see I got 245 00:01:59.17900:01:59.189 volts and then power goes through the 00:02:01.82000:02:01.830 contactor and comes out the other side 00:02:03.46900:02:03.479 to power up the compressor and the fan 00:02:05.60000:02:05.610 and what interrupts this is this little 00:02:08.12000:02:08.130 plunger right here right now I won't 00:02:09.91900:02:09.929 have any voltage because my AC is off 00:02:11.53900:02:11.549 but your contactor coil contacts are 00:02:13.91000:02:13.920 right here on either end where the blue 00:02:15.77000:02:15.780 wire goes to and where the yellow wire 00:02:17.44900:02:17.459 goes to so initially there's power at 00:02:20.87000:02:20.880 the control board in your furnace or 00:02:22.40000:02:22.410 your air handler that will send power to 00:02:25.06900:02:25.079 your thermostat and when your thermostat 00:02:26.90000:02:26.910 is calling for cooling or if you set it 00:02:28.81900:02:28.829 for AC that will close a switch in the 00:02:31.16000:02:31.170 thermostat and send power back down to 00:02:32.96000:02:32.970 the control board and then the control 00:02:34.67000:02:34.680 board will send power out to your AC 00:02:36.94900:02:36.959 unit out here that will be your low 00:02:39.08000:02:39.090 voltage the 24 volts so briefly let's 00:02:41.99000:02:42.000 just look inside here again so that 00:02:43.97000:02:43.980 thermostat wire that comes in to my unit 00:02:45.74000:02:45.750 does brown wire usually it'll have two 00:02:48.92000:02:48.930 wires 00:02:49.30900:02:49.319 inside of it a red and a white as you 00:02:52.13000:02:52.140 can see the red ties in with a wire nut 00:02:54.86000:02:54.870 into the blue wire and my blue wire is 00:02:57.05000:02:57.060 that wire right there going to the 00:02:58.84900:02:58.859 contactor coil on one side but my white 00:03:02.05900:03:02.069 wire coming out of the thermostat wire 00:03:05.22900:03:05.239 goes into another red thermostat wire 00:03:08.14900:03:08.159 and then goes into this white insulator 00:03:11.86900:03:11.879 wire right here which goes back out into 00:03:14.33000:03:14.340 my power saver switch right here so 00:03:17.89900:03:17.909 really what that is is basically this 00:03:20.17900:03:20.189 power saver switch is in series with my 00:03:22.67000:03:22.680 contactor coil sometimes ACS will have 00:03:25.64000:03:25.650 nothing in series with the contactor 00:03:27.47000:03:27.480 coil that just means that the red and 00:03:29.89900:03:29.909 white wire will go straight to the 00:03:31.93900:03:31.949 contactor whereas in my case it goes 00:03:35.42000:03:35.430 into the white wire it goes through that 00:03:37.22000:03:37.230 power saver switch and then comes back 00:03:38.68900:03:38.699 out it goes into this wire nut turns 00:03:41.05900:03:41.069 into this yellow wire and goes on the 00:03:42.86000:03:42.870 other side of the contactor all right so 00:03:45.53000:03:45.540 reason number one wire contactor plunger 00:03:47.78000:03:47.790 may not be pulling in is because your 00:03:49.64000:03:49.650 furnace power switch is off maybe you 00:03:51.70900:03:51.719 were changing the filter and it got 00:03:53.20900:03:53.219 bumped off or maybe some kids were 00:03:54.89000:03:54.900 playing around and turned it off in fact 00:03:56.89900:03:56.909 while I'm on that topic if the inside 00:03:59.30000:03:59.310 fan inside your house if the blower 00:04:01.03900:04:01.049 motor is not working then you should put 00:04:03.64900:04:03.659 the contactor and hold and go figure out 00:04:05.53900:04:05.549 why your fans not working first before 00:04:07.18900:04:07.199 you deal with the contactor if your 00:04:09.05000:04:09.060 furnace is not getting power if that 00:04:10.69900:04:10.709 power switches off that means that 00:04:12.49900:04:12.509 control board is not getting power 00:04:13.58000:04:13.590 therefore it's not going to send 00:04:14.99000:04:15.000 anything outside to the contactor and 00:04:16.90900:04:16.919 reason number two is a condensate 00:04:19.00900:04:19.019 overflow switch especially if you live 00:04:21.43900:04:21.449 in Florida that seems to be a common 00:04:23.12000:04:23.130 problem there or if you have an attic 00:04:25.15900:04:25.169 unit those will almost all the time have 00:04:27.74000:04:27.750 a condensate overflow switch so that 00:04:30.05000:04:30.060 thing will basically interrupt the power 00:04:31.61000:04:31.620 going out to your contactor if your 00:04:34.15900:04:34.169 drain line is plugged and the water is 00:04:36.56000:04:36.570 backing up that float switch will the 00:04:38.24000:04:38.250 water will go up and trip the switch and 00:04:39.92000:04:39.930 kill the power to it that way you don't 00:04:41.68900:04:41.699 have water overflowing and damaging your 00:04:43.76000:04:43.770 ceilings and everything so if you have a 00:04:45.64900:04:45.659 condensate overflow switch check that 00:04:47.95900:04:47.969 out and make sure your drain is not 00:04:49.55000:04:49.560 plugged up and number three is a bad 00:04:51.74000:04:51.750 thermostat or a thermostat working 00:04:53.57000:04:53.580 incorrectly now I say working correctly 00:04:55.87900:04:55.889 because perhaps it could just be dead or 00:04:58.85000:04:58.860 weak batteries when batteries are weak 00:05:00.98000:05:00.990 your display will still be on 00:05:03.05000:05:03.060 that low battery symbol will not always 00:05:05.33000:05:05.340 appear so the display will be on but the 00:05:07.64000:05:07.650 batteries don't have enough power to 00:05:09.26000:05:09.270 close the switch to make a call for 00:05:11.03000:05:11.040 cooling so if your thermostat has 00:05:12.47000:05:12.480 batteries try replacing those another 00:05:14.99000:05:15.000 thing I've seen is the connectors behind 00:05:17.48000:05:17.490 there or loose or sometimes a wires just 00:05:19.52000:05:19.530 broken off altogether so ploy your 00:05:21.40900:05:21.419 thermostat off the wall and just try 00:05:23.36000:05:23.370 gently tugging on each wire and make 00:05:25.12900:05:25.139 sure that each one of them is making a 00:05:26.72000:05:26.730 good connection and if you have recently 00:05:28.12900:05:28.139 replaced your thermostat and you have an 00:05:30.44000:05:30.450 R and an RC pin make sure you have a 00:05:33.05000:05:33.060 jumper between R and RC because R means 00:05:36.23000:05:36.240 power and RC means power for cooling so 00:05:39.29000:05:39.300 if you don't have a jumper between the 00:05:40.43000:05:40.440 two you have no power for cooling and of 00:05:42.44000:05:42.450 course the thermostat could just simply 00:05:44.27000:05:44.280 be bad and an easy way to find out if 00:05:46.25000:05:46.260 it's bad or not is just to bypass it 00:05:48.23000:05:48.240 either at the thermostat or at the 00:05:49.87900:05:49.889 control board I think the best if you're 00:05:52.15900:05:52.169 trying to find out if the thermostat is 00:05:53.42000:05:53.430 bad or not is to bypass it at the 00:05:55.43000:05:55.440 thermostat by putting a little jumper 00:05:57.23000:05:57.240 between R and Y if it kicks on you know 00:06:00.14000:06:00.150 the thermostat is the problem if it 00:06:01.70000:06:01.710 doesn't then there's something else 00:06:03.20000:06:03.210 going on and I have a video of how to 00:06:05.30000:06:05.310 bypass the thermostat and how to bypass 00:06:07.37000:06:07.380 the thermostat at the control board in 00:06:09.05000:06:09.060 my AC fixing playlist so if you want 00:06:11.15000:06:11.160 check those out 00:06:11.99000:06:12.000 and reason number four is bad wiring and 00:06:14.60000:06:14.610 what I mean by that is bad wire 00:06:16.64000:06:16.650 connectors bare wires corroded wires 00:06:19.54000:06:19.550 broken or melted wires so investigate 00:06:23.24000:06:23.250 all your wires especially the low 00:06:25.21900:06:25.229 voltage you know like the thermostat 00:06:27.80000:06:27.810 wires that I showed you in the beginning 00:06:28.88000:06:28.890 of the video look at all those for any 00:06:31.10000:06:31.110 breaks or bare spots then go inside at 00:06:33.44000:06:33.450 the furnace where the control board is 00:06:35.15000:06:35.160 where those thermostat wires go into it 00:06:36.95000:06:36.960 check all of them out make sure there's 00:06:38.96000:06:38.970 nothing broken and while you're at the 00:06:40.79000:06:40.800 control board take out that 3 amp fuse 00:06:43.10000:06:43.110 make sure that thing's not blown if your 00:06:44.87000:06:44.880 3 amp fuse is blown replace it but 00:06:47.00000:06:47.010 before you do usually those 3 amp fuses 00:06:49.31000:06:49.320 blow because there's a short somewhere 00:06:50.96000:06:50.970 so investigate your wires before 00:06:52.55000:06:52.560 replacing a blown fuse this AC season I 00:06:55.19000:06:55.200 had two special cases one was where a 00:06:57.50000:06:57.510 dog actually chewed through the 00:06:59.02900:06:59.039 thermostat wire outside and another one 00:07:01.31000:07:01.320 the customer was going around with a 00:07:02.99000:07:03.000 weed whacker and didn't even notice that 00:07:04.55000:07:04.560 he had chopped his thermostat wire in 00:07:06.50000:07:06.510 half so of course nothing was working 00:07:08.02900:07:08.039 but anyways do investigate your 00:07:09.74000:07:09.750 thermostat wires outside and inside for 00:07:11.99000:07:12.000 any kind of damages and reason number 5 00:07:14.18000:07:14.190 is a bad 5 00:07:15.58000:07:15.590 delay board now my unit does not have 00:07:18.10000:07:18.110 that on here so I can't show you it but 00:07:20.62000:07:20.630 it's just a little either a black box or 00:07:22.84000:07:22.850 a little control board at your outside 00:07:24.90900:07:24.919 unit basically what that does is prevent 00:07:27.55000:07:27.560 your AC unit from short cycling like if 00:07:30.19000:07:30.200 you have a power outage or something 00:07:31.39000:07:31.400 like that your AC unit if it turns off 00:07:33.97000:07:33.980 that thing will prevent it from turning 00:07:35.44000:07:35.450 right back on right away or if 00:07:37.06000:07:37.070 somebody's playing with the thermostat 00:07:38.47000:07:38.480 inside the house it won't let you turn 00:07:40.54000:07:40.550 the AC on and off on and off because 00:07:42.46000:07:42.470 that's bad for the compressor but 00:07:44.14000:07:44.150 sometimes that board goes bad so power 00:07:46.57000:07:46.580 goes into it because it's in series with 00:07:48.43000:07:48.440 the contactor but it never comes back 00:07:50.40900:07:50.419 out to energize that contactor coil and 00:07:52.90000:07:52.910 pull it in if it's just a simple board 00:07:54.70000:07:54.710 what you can do is just take it out of 00:07:56.32000:07:56.330 the circuit so the thermostat wires 00:07:58.45000:07:58.460 coming from inside the house just route 00:08:00.67000:08:00.680 those straight to your contactor coil 00:08:02.62000:08:02.630 turn your AC back on and if it turns on 00:08:04.93000:08:04.940 and everything works great then you know 00:08:06.58000:08:06.590 that that board was the problem and 00:08:08.11000:08:08.120 reason number six is a bad control board 00:08:11.05000:08:11.060 in the furnace or your air handler or 00:08:13.24000:08:13.250 maybe it's a fan relay 00:08:14.68000:08:14.690 maybe there's a burnt-out spot or 00:08:16.36000:08:16.370 there's a relay in there that went bad 00:08:17.80000:08:17.810 but if it's not sending power to the 00:08:19.87000:08:19.880 outdoor unit an easy way to check that 00:08:22.21000:08:22.220 is to take your meter set it to voltage 00:08:24.34000:08:24.350 and with your leads at the furnace 00:08:26.26000:08:26.270 control board with the power on check 00:08:28.96000:08:28.970 between Y and C you should have 27 volts 00:08:32.40900:08:32.419 going outside if you don't have 27 volts 00:08:35.14000:08:35.150 going outside then there's a problem 00:08:37.08900:08:37.099 inside either with the control board or 00:08:39.13000:08:39.140 with that thermostat and I have separate 00:08:41.05000:08:41.060 videos of how to troubleshoot both of 00:08:43.08900:08:43.099 those and while I'm talking about that 00:08:45.10000:08:45.110 another easy way to check that is take 00:08:48.49000:08:48.500 your two meter lead set it to voltage 00:08:49.93000:08:49.940 and then your thermostat wire that comes 00:08:51.82000:08:51.830 out of the house and into your unit the 00:08:53.38000:08:53.390 brown wire that has the red and the 00:08:55.32900:08:55.339 white wire put your meter leads on the 00:08:57.46000:08:57.470 red and the white if it has 27 volts 00:08:59.71000:08:59.720 coming out that means whatever is 00:09:01.78000:09:01.790 interrupting your power the low voltage 00:09:03.49000:09:03.500 is going to be outside if you don't have 00:09:06.01000:09:06.020 27 volts or 24 volts that means the 00:09:08.65000:09:08.660 problem is inside the house so if you 00:09:10.72000:09:10.730 have voltage out heater problems out 00:09:12.57900:09:12.589 here no voltage out here problems inside 00:09:14.94900:09:14.959 and reason number seven is a bad power 00:09:18.97000:09:18.980 saver switch this box right here not all 00:09:21.97000:09:21.980 houses have this but if you do generally 00:09:24.79000:09:24.800 it'll be by your disconnect and what 00:09:26.80000:09:26.810 that does is on really hot 00:09:29.07000:09:29.080 The Electric Company cycles people on 00:09:30.99000:09:31.000 and off sporadically so not everybody is 00:09:33.24000:09:33.250 running their AC at the same time and 00:09:35.13000:09:35.140 they give you like 10 or 15 bucks off a 00:09:37.20000:09:37.210 month for doing that but sometimes this 00:09:39.51000:09:39.520 power saver switch can become defective 00:09:41.28000:09:41.290 so power goes into it but it never comes 00:09:43.68000:09:43.690 back out to your contactor if you think 00:09:45.51000:09:45.520 the power saver switch is your issue I 00:09:47.46000:09:47.470 have a video specifically just for the 00:09:49.89000:09:49.900 power saver switch how you can bypass to 00:09:51.84000:09:51.850 check if that's your problem or not and 00:09:53.76000:09:53.770 then call the electric company and have 00:09:55.14000:09:55.150 them fix their box and reason number 00:09:57.39000:09:57.400 eight is a tripped high pressure switch 00:10:00.00000:10:00.010 or a low pressure switch or maybe they 00:10:02.19000:10:02.200 could be bad - if you're not sure what 00:10:04.29000:10:04.300 I'm talking about an easy way to see if 00:10:06.18000:10:06.190 you have one or not one is to look at 00:10:08.25000:10:08.260 your wiring diagram on the back of your 00:10:09.87000:10:09.880 door and two is to just look on top of 00:10:12.00000:10:12.010 your unit and you have two refrigerant 00:10:14.10000:10:14.110 pipes going out of your compressor one 00:10:15.78000:10:15.790 is thick one is thin see if there's 00:10:17.94000:10:17.950 anything attached to those pipes if you 00:10:19.77000:10:19.780 look from the top 00:10:20.43000:10:20.440 the low pressure switch is going to be 00:10:22.41000:10:22.420 mounted to your thicker pipe and then 00:10:25.17000:10:25.180 the high pressure switch will be mounted 00:10:26.88000:10:26.890 to the discharge line or the thinner 00:10:28.71000:10:28.720 pipe they usually look like black 00:10:30.60000:10:30.610 cylinders or a black disc with two wires 00:10:33.30000:10:33.310 coming out of it and their function is 00:10:35.31000:10:35.320 to interrupt the power if your 00:10:37.05000:10:37.060 refrigerant pressures or freon pressures 00:10:39.15000:10:39.160 are either too high or too low in the 00:10:41.40000:10:41.410 system a lot of times the high pressure 00:10:43.53000:10:43.540 switch on the thin line will be 00:10:45.63000:10:45.640 resettable it'll have a little red 00:10:47.22000:10:47.230 button on it you can press that and if 00:10:49.53000:10:49.540 it presses in you hear a click that 00:10:51.42000:10:51.430 means that was tripped and you just 00:10:52.65000:10:52.660 reset it and your AC will start working 00:10:54.90000:10:54.910 normally but that also means that your 00:10:56.91000:10:56.920 pressures for some reason got too high a 00:10:58.80000:10:58.810 lot of times the reason for that is 00:11:00.99000:11:01.000 because your condenser coil is dirty so 00:11:03.32900:11:03.339 even if it looks clean how it holds it 00:11:05.37000:11:05.380 down and spray it down make sure it's 00:11:06.69000:11:06.700 clean and if it looks dirty well then of 00:11:08.94000:11:08.950 course it's dirty as for the low 00:11:10.44000:11:10.450 pressure switch if that's tripped those 00:11:12.66000:11:12.670 are usually not resettable that just 00:11:14.82000:11:14.830 means your refrigerant levels are very 00:11:16.41000:11:16.420 low oftentimes when those are tripping 00:11:19.07900:11:19.089 your unit will turn on it'll run for a 00:11:21.24000:11:21.250 little bit and then turn back off turn 00:11:23.31000:11:23.320 back on run for a little bit turn back 00:11:25.11000:11:25.120 off 00:11:25.53000:11:25.540 if the low-pressure trip is switched and 00:11:27.72000:11:27.730 it's not resetting automatically that 00:11:29.55000:11:29.560 means your freon pressures are very low 00:11:31.29000:11:31.300 to check that you can either disconnect 00:11:33.30000:11:33.310 the wires and omit out for resistance 00:11:35.01000:11:35.020 you can check voltage to see if you have 00:11:37.29000:11:37.300 voltage coming in and voltage coming out 00:11:39.03000:11:39.040 or you can bypass it and see if the unit 00:11:41.55000:11:41.560 will turn on without 00:11:42.42000:11:42.430 but that is of course just for testing 00:11:44.28000:11:44.290 purposes you do not want to leave it by 00:11:46.01900:11:46.029 pass because there's a reason why it 00:11:47.73000:11:47.740 tripped in the first place but once in a 00:11:49.59000:11:49.600 while 00:11:50.07000:11:50.080 the high pressure switch or low pressure 00:11:51.69000:11:51.700 switch are just simply bad I don't have 00:11:54.36000:11:54.370 those too often but once in a while I'll 00:11:56.01000:11:56.020 come across the high pressure switch for 00:11:57.60000:11:57.610 example that's just stuck open and it 00:11:59.82000:11:59.830 will not close but when I check the 00:12:01.35000:12:01.360 pressures of the freon everything is 00:12:03.54000:12:03.550 good in that case you just need to 00:12:05.10000:12:05.110 replace that high pressure switch and 00:12:06.66000:12:06.670 you'll be good to go 00:12:07.86000:12:07.870 but anyway I'm spending a little too 00:12:09.24000:12:09.250 much time in the pressure switches those 00:12:10.98000:12:10.990 tend to be a little bit more complicated 00:12:12.81000:12:12.820 you might be better off calling a tech 00:12:14.67000:12:14.680 at that point and reason number nine why 00:12:17.73000:12:17.740 your contactor might not be pulling in 00:12:19.26000:12:19.270 is a bad contactor itself now to check 00:12:22.26000:12:22.270 that it's pretty easy all you got to do 00:12:23.73000:12:23.740 is set your meter to voltage and put 00:12:26.19000:12:26.200 your muna leads on either end of the 00:12:27.57000:12:27.580 contactor coil where that yellow wire 00:12:29.28000:12:29.290 and blue wire came in and mine and see 00:12:31.65000:12:31.660 if you have 27 volts there if there's 00:12:33.57000:12:33.580 voltage going to the contactor 00:12:35.25000:12:35.260 yep that little plunger is not pulling 00:12:37.19900:12:37.209 in that means you have a bad contactor 00:12:39.12000:12:39.130 coil you could also disconnect the wires 00:12:40.92000:12:40.930 and check for resistance if it's a while 00:12:42.90000:12:42.910 it's bad as well and another thing I 00:12:44.85000:12:44.860 should mention especially if you are 00:12:46.26000:12:46.270 down south in like Texas and Arizona 00:12:47.94000:12:47.950 make sure you check if your contact your 00:12:50.67000:12:50.680 contacts have any bugs or ants inside of 00:12:53.79000:12:53.800 them because they could be preventing 00:12:55.14000:12:55.150 that plunger from pulling it and reason 00:12:57.42000:12:57.430 number 10 and the final reason is a bad 00:12:59.55000:12:59.560 transformer not a lot of air 00:13:01.59000:13:01.600 conditioners will have a transformer or 00:13:03.84000:13:03.850 at least in Minnesota they don't I don't 00:13:05.22000:13:05.230 know maybe some other states have a lot 00:13:06.63000:13:06.640 of them but if your unit has a 00:13:08.25000:13:08.260 transformer there's a chance that that's 00:13:10.05000:13:10.060 bad as well and that's what's causing 00:13:11.57900:13:11.589 that so check if your Transformers bad 00:13:13.47000:13:13.480 you would just have to look up a video 00:13:14.69900:13:14.709 on how to mount a transformer and their 00:13:17.43000:13:17.440 resistance and just see if you have the 00:13:18.93000:13:18.940 right readings if you have o/l or open 00:13:21.24000:13:21.250 line instead of a reading well then you 00:13:23.10000:13:23.110 know for sure that your transformer is 00:13:24.60000:13:24.610 bad but if you have a burnt-out 00:13:26.13000:13:26.140 transformer make sure you replace your 00:13:28.59000:13:28.600 contactor first because your contactor 00:13:31.14000:13:31.150 may have been the reason why your 00:13:32.51900:13:32.529 transformer burned out so if you have a 00:13:34.74000:13:34.750 bad transformer replace both the 00:13:36.93000:13:36.940 contactor and the transformer and you 00:13:38.79000:13:38.800 should be good to go and that covers 00:13:40.88900:13:40.899 just about all of them I did not cover 00:13:42.81000:13:42.820 anything about communicating systems 00:13:44.28000:13:44.290 because that's like a whole nother beast 00:13:46.59000:13:46.600 you're better off calling a technician 00:13:48.18000:13:48.190 at that point what I mean by 00:13:49.56000:13:49.570 communicating systems is instead of like 00:13:52.11000:13:52.120 your normal thermostat terminal strip on 00:13:54.42000:13:54.430 your thermostat and control 00:13:55.65000:13:55.660 bored and outside like the G the RW the 00:13:58.89000:13:58.900 Y all you're gonna have is a green 00:14:00.66000:14:00.670 little molex plug that says ABCD those 00:14:03.87000:14:03.880 are harder to troubleshoot and diagnose 00:14:05.73000:14:05.740 so yeah like I was saying you're better 00:14:07.56000:14:07.570 off just calling a technician at that 00:14:09.03000:14:09.040 point if you have that kind of system 00:14:10.62000:14:10.630 well guys and those were the ten reasons 00:14:12.18000:14:12.190 why your contactor might not be pulling 00:14:13.95000:14:13.960 in I hope you found this video useful if 00:14:15.99000:14:16.000 you have something to add or if you have 00:14:17.49000:14:17.500 some reasons that I missed please do so 00:14:19.38000:14:19.390 in the comments below so everybody else 00:14:21.03000:14:21.040 can learn from that as well 00:14:22.29000:14:22.300 a lot of times the best part of the 00:14:23.67000:14:23.680 video is the commentary below so make 00:14:25.80000:14:25.810 sure you check that out thank you so 00:14:27.21000:14:27.220 much for watching this video don't 00:14:28.62000:14:28.630 forget to mash that like button under 00:14:29.94000:14:29.950 way out and we'll see you next time
