Compressor starts, but airhandling motor does not

Sounds like you may have a bad fan capacitor or a bad fan motor. Remove the inside cover from the air conditioner and access the squirrel cage fan or, remove the shroud from the top to access the fan that way. Have someone turn the thermostat on as you spin the fan motor by hand. If the motor starts and runs, then you have a bad capacitor. If the fan motor still does not come on, then there are a couple of possible problems.

When you turn the thermostat to fan, do you hear an audible click in the control unit of the ac? If so, then you know that the thermostat is sending 12V to the fan relay on the board.

I think the motor just may be frozen up. Try spinning the motor by hand and see what happens. Again, if it starts, then just lube the shaft points on the motor with some WD-40 and all should be fine. If the fan motor starts and then after the cycle, does not restart, then you definitely have a bad capacitor.

Hope this helps,
