Freezer evaporator sensor disorder — OPEN

From Service Manual 414919, p.51:

1.Turn main power OFF then ON to run self-diagnosis check; inspect F-EVAP SENSOR wiring, connector, and resistance/voltage per temperature table.

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.
