WM2277 WASHER PAGE 27 of 84 TRAINING MANUAL
HALL EFFECT SENSOR
The Hall Effect sensor is easily
removed and replaced. You’ll have to
remove the rotor and stator to access
the sensor. When replacing the rotor,
you’ll probably need a helper to hold
the drum in place when you push the
rotor onto the shaft. Otherwise, the
drum may move forward enough to
make replacing the bolt difficult. The
helper can also hold the drum from
turning while you tighten the bolt.
Before going to this trouble, check the
connector on the main board. The
motor connector is the red one closest
to the heat sink. Pull the connector off
and verify the board is receiving a
signal from the sensor.
