I ordered a mother board but before I replaced watched a video that explained how to test the compressor had me check the signal from the mother board to the inverter that was good had me check 110 VAC to the inverter that was good than had me tale connmector off compressor and ohm out the three windings and they were good so it said to replace the inverter and that fixed my problems. I took the option of having the part delivered in 2 days and it showed up the second day thank you for the great service
