My dad replaced the bearings in my Amana Air Command blower motor. When I hooked it up again the motor started to smoke and didn't turn. If we put power to the blower in the shop, it works, but now when I hook it up... nothing. The red diagnostic light on the furnace blinks once when I turn it on, but it's like the blower is getting no power at all, or no signal to turn on.
One thought: the capacitor may be drained at this point. Is that a problem? Would it need to be charged up before the blower will work? (I don't know much about capacitors other than not to touch them). Also, from the blower I have 4 wires that hook to the furnace wiring panel like this:
Park - yellow
Park - red
Heat - blue
Cool - black
I've always connected them this way but wonder if something is wrong here.
Any help would be appreciated!
If you have a capacitor tester you can measure the capacity of the capacitor in uF (micro-ferrics). The capacity should be stamped on the capacitor somewhere, if the measured uF are lower than the listed uF than replace the capacitor. As an HVAC repairman I always replace capacitors along with the motor to avoid future problems.
