Indoor unit EEV close failure (1st detection)
From Service Manual 895349, p.41:
1.Check whether EEV wire is connected to indoor unit PCB correctly; check EEV coil insertion.
2.Measure door lock assembly resistance across the PTC terminals. Expected: ~200 ohms cold, rising sharply once energized.
3.Inspect strike and latch alignment. A warped door or misaligned strike prevents the switch stack from closing in the correct sequence.
