Question about Heating & Cooling
Okay. To begin with the fan in unit wasn't kicking on so I replaced capacitor in the video and also replaced contact switch which is also in video. Unit ran great. Switched on and off at set temp and no problems for past two weeks. Today all of a sudden white smoke with electrical smell started coming out of vents in house. Looked in
Try spinning the blower motor. If it does not spin freely then the motor is bad. The capacitor being bad will cause this to happen. If the capacitor was not the right microfarad that will also cause the motor to go bad. Also you can just put you nose to the blower motor and try to smell if it smells burnt

SOURCE: My central air never kicks off
Sounds like you need to recharge it .. To tell while the unit is running go outsiode and feel the large insulated copper line going to the unit it should be cold to point od sweating like a can of coke you take out of the refrigerator and sit on the counter. also feel the air coming out of the unit outside it should be warmer than the outside air if not your freon is low

SOURCE: I have a 561c central
Sounds like you need another capacitor since it will run if you turn it by hand to get it started. If you have a clamp on ammeter check the current draw on the fan motor.

Well, the answer is yes. I have seen a bad capacitor cause a fan motor to run backwards. BUT..... After replacing the capacitor and WIRING it up the right way, everything should be fine. A lot of aftermarket condenser fan motors are reversible, so it can run counter-clockwise (CCW) or clock-wise (CW). However, most factory fan motors come one directional and on your specific unit, the air should always push out of the top. Running the unit with the fan going backwards will actually some-what do it's job, but damage other components like the compressor because it runs at higher operating pressures than what it is designed for.
Have someone else look at it! That's going to be the best advice I can give you. If they can prove that a capacitor caused the motor to permanently run backwards..... I want to know! Hope this helps and good luck with your unit.
