Compressor IPM Shut Down error – IPM operating

From Service Manual 620309, p.41:

1.Check soldering status of inverter PCB for short circuits; check if DC 15V output is less than 13.5V; check compressor and cycle.

2.Measure line voltage at the power cord terminal block. Expected: 120 VAC (L1 to neutral) or 208 to 240 VAC between L1 and L2 under load.

3.Inspect the cord strain relief and terminal block screws for signs of arcing or heat discoloration. Loose connections here mimic an intermittent power failure to the control board.
