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.
Sail Switch Replacement
1. Discontinue electrical power to the dryer.
2. Remove the two (2) screws which hold the sail switch box cover to 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 switch in place.

To Adjust Sail Switch
With the dryer operating at a high temperature setting, pull the sail switch away from the burner. The sail switch
should open and extinguish the burner. The dryer will continue to run for 3-minutes or until 100º F (38º C) is
reached. The computer will display no airflow. If the sail switch circuit does not operate as described, bend the
actuator arm of the sail switch accordingly until proper operation is achieved. To check proper open position of
sail switch, open main door, manually depress main door switch and start dryer. With the main door open and the
dryer operating, the sail switch should be open, and the burner should not come on.
