Fan motor IPM high temperature error - IPM
From Service Manual 325968, p.20:
1.Check whether the outdoor unit fan motor is rotated and locked or not.
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.
