Customer Questions and Answers for Control Board by Whirlpool

Hi R.H. Make sure your unit is in cooling mode. Then check the inverter red/white and red wires for 3 - to - 6 vdc. Check P7-3 (red) and P7-8 (red/white) on the main control board for 3-to-6 vdc. If the voltage is not present, replace the main control board. If there is voltage, then unplug or disconnect the unit. Disconnect the wire connector at the compressor. Set your ohm meter to Rx1 scale. Touch the meter leads on any two pins. You should have a reading of 9 to 10 ohms. Check between all three sets of pins to test all three windings. Touch one meter lead to compressor (green) ground and test all three pins to see if the compressor is grounded. If so then the compressor is either bad from improper ohms, or shorted to ground. The compressor part # is 8201675. Thank you.
