To Replace the Hi-Limit Thermostat (330°)
This thermostat is an important safety device serving as an
added protection against failure of the air sail switch to open
in the event of motor failure or reduced air flow conditions.
IMPORTANT: Under no circumstances should heat circuit
safety devices ever be disabled.
1. Discontinue power to dryer.
2. Disconnect wires from hi-limit thermostat.
3. Loosen the two screws securing thermostat to the burner
box.
4. Reverse procedure for installing new thermostat.
Sail Switch Assembly
The sail switch is a heat circuit safety device, which controls
the heat circuit only. When the dryer is operating and there
is proper air flow the sail switch damper pulls in and closes
the sail switch, providing all the other heat-related circuits
are functioning properly. If an improper air flow occurs, the
sail switch damper will release, and the circuit will open.
IMPORTANT: Under no circumstances should heat circuit
safety devices ever be disabled.
To Replace Sail Switch
1. Discontinue power to the dryer.
2. Remove the two (2) screws, which hold the sail switch
box.
3. Disconnect the two (2) wires from the switch.
4. Disassemble sail switch from mounting bracket by
removing the two (2) screws securing the switch in place.
5. Reverse this procedure for installing new sail switch.
Adjust the sail switch as described in the next section.
To Adjust Sail Switch
1. Operate the installed dryer normally to verify that the heat
system is fully operational.
2. Open the main dryer door.
3. Manually depress the door switch actuator.
4. While continuing to depress the door switch actuator, and
with the door open, start the dryer.
5. If the heat system is not activated in 15-seconds, the sail
switch is properly adjusted.
6. If the heat system is activated, the sail switch is improperly
adjusted and must be readjusted by bending the actuator
arm of the sail switch toward the front of the dryer. If the
actuator arm is bent too far toward the front of the dryer,
the dryer may not have heat when needed. After any
adjustments of the sail switch, the above procedure must
be repeated to verify proper operation.
CAUTION: Do not disable this switch by taping or
screwing sail switch damper closed. Personal injury or
fire could result.
