Compressor low voltage error – AC input voltage

From Service Manual 621766, p.18:

1.Check input voltage. Error occurs when input voltage is below AC 53V (for 110~127V input) or AC 106V (for 220~240V input).

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.
