Main PCB to Inverter PCB communication error
From Service Manual 866151, p.43:
1.Check cable connections; if no cable problem found, replace Main PCB.
2.Inspect the communication harness between the main control and the UI board for bent pins or unseated connectors at each end.
3.Measure supply voltage to the UI board. Expected: 5 VDC at the interface connector; a low or missing rail points back to the main control supply.
