N. Automatic Reset Thermostat

This is located inside the dryer in the lint compartment above the lint drawer. This thermostat senses the heated air after it has passed through the basket. If the air temperature gets too hot, the thermostat will shut off the burner. The dryer will not heat up until the air temperature cools down. At this time, the thermostat will reset. Basket and blower will run, but dryer will not heat.

O. Lint Drawer

The lint drawer is a pullout type and is located at the bottom of the dryer in the lint compartment. Simply grab the lint drawer handle, slide out the drawer, brush off the lint, and slide the drawer back in. The lint screen must be kept clean in order for the dryer to operate properly and efficiently.

P. Lint Drawer Switch

The lint drawer switch is located in the lint compartment and attached to the side of the lint drawer track. The lint drawer switch insures that the dryer will operate only when the lint drawer is completely closed. This is a safety device and should never be disabled.

Q. Steam Damper System

The newest type system is called the steam damper. It is shown to the right and it uses a piston with compressed air to open and close the steam damper which in turn allows the air to flow either through the coil for heat, or under the coil for cool down. Air supply is 80 PSI (+/- 10 PSI).
