Freezer compressor motor is mechanically

From Service Manual 391053, p.25:

1.Check if compressor and cycle are normal; check input voltage; check soldering of inverter PCB for short circuits.

2.Measure the drive motor winding resistance at the main control connector. Expected: 2 to 6 ohms between winding pairs.

3.Rotate the drum by hand and check for free rotation. Inspect the belt and pulley for glaze or wear; a slipping belt mimics a motor fault under load.
