Steveo for Model Number PCF25PGSA GE Monogram Condenser fan runs but compresser doesn't. Replaced main board to no avail. Have 120 volts to inverter on the side of the compresser but no start. Any idea how to test inverter or to know what the signal is suppose to be on the red and white wires coming from the main board? Tks
Answer Hi Stevo. Remove all compressor leads connected to the inverter board after marking them to insure proper replacement. I would use a volt/ohm meter part # MA-DM1 to assist. you in your diagnosis. Make sure all windings ohm out to 10 ohms and not shorted to chassis ground. The brown , blue , and black wire going directly to the compressor. From the board on the red and white input voltage to the inverter board is 120 vac. the output is measures on all 3wires from 80-240 vac and should read 57-104Hz. It is a 3-phase inverter board output and it will damage the compressor when 120 vac is directly applied to the compressor. If your model ends in the last few letters (after the letter A)- in BB, CC or WW the inverter part # is WR87X29409 is not available. Sorry. Thank You. Read More...
