Whirlpool washer model GHW9400pl4 has worked stellar till this point.Washer does all except agitate or spin out.Check motor all windings they ohm out at 6 ohms=ok electrically.Drum does spin freely when turned by hand with no binding or noise.Have 120 v input to MCU. Fuse on board appears to be good-unless Im getting feedback from circuit.Any other test I can do before I rule MCU DOA?? Can I check output from MCU to motor?If so what voltages am I looking at.Thanks ....Bob
