Board is flashing 4 times which says it is a locked compressor, the tech tested the 3 leads on the compressor, they all tested 12 ohms each. He tested them to ground and that passed. Control board has 3 wires going to the compressor, each wire to ground test 125 volts dc. Is this AC voltage that goes to the compressor or DC. Is it the compressor that has failed, or the board?
