Indoor unit EVAP IN sensor breakaway

From Service Manual 904646, p.18:

1.Access service mode to confirm the active fault code and read stored error history.

2.Measure door lock assembly resistance across PTC terminals. Expected: ~200 ohms cold.

3.Inspect strike and latch alignment. A misaligned strike prevents the switch stack from closing.
