00:00:06.769 00:00:06.779 available on our website and the help
00:00:09.440 00:00:09.450 you need to do the repair yourself if
00:00:12.770 00:00:12.780 your furnace blower is not running here
00:00:15.860 00:00:15.870 are the top four most probable causes
00:00:19.330 00:00:19.340 the blower motor blows air through the
00:00:22.099 00:00:22.109 return vent pass the heat exchanger and
00:00:24.529 00:00:24.539 into the homes venting if the blower
00:00:27.710 00:00:27.720 motor does not run first confirm that
00:00:30.140 00:00:30.150 the motor is receiving power if it is
00:00:32.900 00:00:32.910 then it's likely the motor has burned
00:00:34.940 00:00:34.950 out if the motor hums and the blower
00:00:38.360 00:00:38.370 wheel is unobstructed but will not turn
00:00:40.640 00:00:40.650 freely it's likely the motor bearings
00:00:43.340 00:00:43.350 are locked up and the motor will need to
00:00:45.290 00:00:45.300 be replaced the capacitor stores an
00:00:49.850 00:00:49.860 electrical charge and then releases it
00:00:52.190 00:00:52.200 in order to start the blower motor if
00:00:54.580 00:00:54.590 the blower motor does not start or start
00:00:57.860 00:00:57.870 slowly the capacitor may be faulty when
00:01:01.820 00:01:01.830 a capacitor fails it will often bulge or
00:01:04.340 00:01:04.350 leak if there are no visible signs of
00:01:07.940 00:01:07.950 damage you can test the capacitor using
00:01:10.370 00:01:10.380 an analogue style ohmmeter or a
00:01:12.200 00:01:12.210 capacitor tester to determine if the
00:01:14.690 00:01:14.700 component is working properly before
00:01:18.710 00:01:18.720 handling the capacitor you should
00:01:20.960 00:01:20.970 release the potentially stored
00:01:22.430 00:01:22.440 electrical charge to avoid injury you
00:01:25.370 00:01:25.380 can do this by placing a screw driver
00:01:27.200 00:01:27.210 with an insulated handle across each set
00:01:29.780 00:01:29.790 of terminals be very careful not to
00:01:32.480 00:01:32.490 touch the screwdriver blade when doing
00:01:34.640 00:01:34.650 this the Control Board regulates the
00:01:38.810 00:01:38.820 power supply to all of the furnace
00:01:40.550 00:01:40.560 components a defective control board may
00:01:43.969 00:01:43.979 not send voltage to the blower motor an
00:01:47.980 00:01:47.990 incoming power problem could also result
00:01:50.690 00:01:50.700 in the blower not running make sure the
00:01:53.810 00:01:53.820 furnace power switch is in the on
00:01:55.399 00:01:55.409 position and check to see if a circuit
00:01:58.250 00:01:58.260 breaker has tripped or a fuse has blown
