Fan motor RPM measured less than 100 rpm after

From Service Manual 585774, p.26:

1.Check dry fan motor connections and measure fan motor coil resistance.

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.
