Main Door Switch
The main door switch is located near the main door hinge.
When the main door opens, the switch will also open,
preventing the dryer from operating. The main door switch
is a safety device and should never be disabled.
Burner Hi-Limit (Gas Models Only)
A burner hi-limit thermostat is located on the burner. This is
a manual reset disc-type thermostat set at 330° F (165° C).
If the flame in the burner should get too hot, this thermostat
will shut off the burner. This is generally caused by low
airflow through the dryer.
Sail Switch (Gas Models Only)
The sail switch is located on the front of the burner box. A
sail switch consists of a round damper plate on a lever arm,
which is in contact with an electric switch. When the fan/
blower comes on, it draws air through the burner box. This
creates a negative pressure inside the burner box, and this
negative pressure pulls in the round damper and activates
the sail switch.
Tumbler Hi-Limit
This is located in the lint compartment above the lint drawer.
This bracket consists of two devices. One is a temperature
sensor probe and the other is a hi-limit thermostat, which is
set at 225° F (107° C).
