J. 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.
K. 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 air blower
comes on, it draws air through the gas burner.
This creates a negative pressure inside the
burner box, and this negative pressure pulls in
the round damper and activates the sail switch.
If there is improper airflow, the damper will
not pull in, preventing the burner from starting.
Improper airflow can be caused by improperly designed exhaust ducting where the duct run is too long or has too
many sharp bends in it. It can also be caused by a lack of make-up air.
L. HI-LIMIT (GAS MODELS ONLY)
A hi-limit thermostat is located at the burner.
This is a manual reset disc-type thermostat set
at 330º F. 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. The heat will not ignite/fire unless
this manual reset thermostat is reset.
