Motor Removal; Motor Running; Motor Off - GE DBL333 Technical Service Manual

The motor contains a centrifugal switch which serves
three purposes: It disengages the motor start
winding, engages the motor run winding and closes
the circuit for the heat source. When the motor is
off, the switch completes a circuit from M5 through
the motor start winding to M4. The contact M1 to
M2 is open. Immediately as the motor is started,
centrifugal force pulls the switch activating collar in
on the motor. This opens the circuit through the
start winding and completes the circuit M6 through
the run winding to M4. The contacts M1 to M2 close
to activate the heat source.

MOTOR OFF

MOTOR RUNNING

To check the switch, disconnect the dryer from power
and remove the drum. If the motor starts to run and
stops when the start switch is released, place an
ohm meter across terminals M5 and M6 and
manually pull in on the collar to activate the switch.
You should read continuity. If the motor runs and
there is no heat, activate the switch and check
between M1 and M2. You should read continuity.

Motor Removal

To replace the motor, disconnect power, remove the
top and front panels, belt and dryer drum. Remove

original tape cannot be reused, use aluminum tape
WD49X27 to seal the cover.
Unscrew the blower wheel in a clockwise direction
