Safety Switches; Centrifugal Switch; Belt Switch - LG DLEX8388WM Training Manual

TRAINING MANUAL
The centrifugal switch slides back and forth on the motor's shaft to operate the contacts
as shown in the previous diagram. This switch provides safety in the event the motor fails.
When the motor is running, centrifugal force causes the weight (black wing in photo) to
slide back toward the motor windings. This motion allows electricity to operate the
heater (electric element or gas valve). If the motor stops, the weight slides forward and
turns the power off.
RUN POSITION
There is an additional safety in the form of a belt switch that shuts off power to the
electric motor if the belt breaks. Belt tension holds the switch closed. If the belt breaks,
the switch opens and power to the motor is cut. When the motor stops, the centrifugal
switch functions as a safety device to turn off the fuel (gas or electricity).

SAFETY SWITCHES

STOP POSITION
The centrifugal switch includes a multi-pin
connector (shown).
The belt switch is simple. If the belt breaks,
the spring pulls the lever down and it
presses the switch to turn the dryer off.
