To Replace Lint Compartment Hi-Heat Protector (225º F [107º C]) Thermostat

This thermostat is part of the “sensor bracket assembly” and is secured to the underside of the basket wrapper in the lint compartment. As a safety device, this thermostat will open (shut off) the heating unit circuit if an excessive temperature occurs. The dryer motor will remain on, even if the thermostat is open.

1. Disconnect electrical power to dryer.

2.Open lint door.

3.Locate sensor bracket assembly and loosen the two (2) Phillips head screws securing bracket assembly to the tumbler wrapper.

NOTE: DO NOT remove the screws.

4.Remove bracket assembly by slightly sliding bracket toward the rear of the dryer and to the left.

5.Disconnect sensor bracket harness connector and remove bracket assembly from dryer.

6.Disconnect the two (2) orange wires from the thermostat.

7.Disassemble thermostat from bracket assembly by removing the two (2) mounting screws, washers and nuts.

8.Reverse this procedure for installing a hi-heat protector thermostat.

9.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.
