To Replace Lint Compartment Hi-Heat Protector (190° F [87° C]) Thermostat
This thermostat is part of the “lint box assembly” and is
secured to the top lint box beneath tumbler . As a safety
device, this thermostat will open (shut off) the heating unit
circuit if an excessive temperature occurs. The dryer motors
will remain on, even if the thermostat is open.
IMPORTANT:
Under no circumstances should
heat safety devices be disabled.
1. Discontinue electrical power to the dryer.
2. Remove lower access panel by removing the four
screws.
3. Locate exhaust hi-limit at front left side of lint box.
Remove wires from thermostat and remove the two
11/32” Hex nuts.
4. Reverse this procedure for installing a hi-heat protector
thermostat.
5. Reestablish electrical power to the dryer.
D. SAIL SWITCH ASSEMBLY (GAS MODELS ONLY)
The sail switch is a heat circuit safety device which controls the burner circuit only. When the dryer is operating and
there is proper airflow, the sail switch damper pulls in and closes the sail switch. Providing all the other heat-related
circuits are functioning properly, ignition should now be established. If an improper airflow occurs, the sail switch
damper will release, and the circuit will open.
C. THERMOSTATS
To Replace Burner Hi-Limit Thermostat (Gas Models Only)
This thermostat is an important safety device serving as an added protection against failure of the airflow (sail switch)
to open in the event of motor failure or reduced airflow condition.
IMPORTANT:

1. Discontinue electrical power to the dryer.
2. Disconnect wires from hi-limit thermostat.
3. Remove screw securing thermostat to the heat duct. Remove thermostat.
4. Reverse procedure for installing new thermostat.
5. Reestablish electrical power to the dryer.
