My unit turns on, but the blower fan will not start unless I start it by hand then it does fine until the furnace cuts off then starts up again. Then I have to give the fan a hand again, could it be that the fan motor is dirty and just needs cleaning?


I hope you're using something besides your hand to do that, but it sounds like the capacitor if that's what's happening. Most often mounted to the front of the fan housing.
