SOURCE: goodman split unit that heats instead of cools
Hi, Could be a run capacitor on the fan motor. They usually swell up and or leak when they go bad. If not, the only real way to test them it with a specific capacitor tester. A new capacitor would be cheaper. Make sure that the outside unit is disconnected from power before opening it up, try to spin the fan blade by hand. If it doesn't spin freely it may need oiled if possible. See above solution. Your problem is the fan motor though so if this don't do it, It will have to be replaced. If this helps, Please rate my solution. Thanks, kstfas

On your t-stat you have Y, W1, W2, R, O, G, B or C or X. Y is your cooling circuit and will be the same in the air handler and heat pump unit, use the yellow wire for this circuit. W1 and W2 are your back up elec. or gas heat. Depending on how many kws or heat strips you have and t-stat wires you will put the white wire to W1 in both the t-stat and air handler. W2 is for your second stage back up heat if air handler calls for it, this will be a tan or brown or black t-stat wire and goes to W2 on t-stat and air handler. R is half of your 24v control power from the transformer and is the red wire and goes to the t-stat, air handler, and heat pump. O is for the reversing valve in the heat pump that switches it from heating and cooling. You guessed it the orange wire connect to t-stat and heat pump. G is for the blower and is the green wire to the t-stat and air handler. B or C or X is known as the common which is the other half of control circuit from 24v transform it is the blue wire and goes to the t-stat, air handler, and heat pump.

Just take out the fan and capacitor they are not OEM so any fan motor would work as long as same Horsepower and milti speed. And the capacitor is a 5 uf or maybe 7.5. You might have to cut off the shaft of the new fan motor so it don't stick out.. You can get a new fan and capacitor at any Heating and Air parts house. And you are sure they are bad you ohmed them out? Fans are not cheap about 50-75 bucks retail. Let me know how it goes. ken

Defective thermostat wire.
Defective contactor.
With the t-stat set for cool and turned down on a low temperature, check for 24 volts at the contactor low voltage hookup. If you have 24 volts, replace the contactor.
You can manually close the contactor to make sure the high voltage is going through it.
