There are two types of thermostats employed on most Whirlpool, Kenmore, GE, and Maytag electric and gas dryers – Fixed and Adjustable. These two types have three basic apps in a dryer – as operating or cycling thermostats, safety thermostats, and cool-down thermostats.

An operating or cycling (bias) thermostat is applied to control the air temperature in the dryer. A single fixed thermostat, various switch-selected fixed thermostats, or an adaptable thermostat may be in control. These thermostats are located in the exhaust airstream of the dryer and have commonly closed contracts. The contacts open with temperature rise and control the electrical current to the gas burner or electric-heat-element circuitry. In a heap of apps a second, commonly open, contact is used to control timer operation.

Safety thermostats are applied to prevent exuberant temperatures within the dryer. Dryer safety thermostats, or thermal fuses, are always fixed, or the non-adjustable type. They are located at strategic locatings in the burner area, heater element housing, or fan-scroll housing, depending on the design of the dryer model. In most, if not all dryer applications, thermal fuses and safety thermostats have ordinarily closed contacts that open the circuit and prevent electrical current to the heat source in the event that a lot of failure or an unnatural rise in temperature. Some of the earlier dryer safety thermostats employed with galore manual ignition burners had normally-open contacts that close and energize an unlatching solenoid.

Cool-down thermostats are employed to provide motor operation for the duration of the cool-down on galore Whirlpool and Maytag Dryer designs. These thermostats have normally-open contacts that close for the duration of the heat phase of the cycle. At the end of that phase, the timer or relay contacts are opened and the dryer proceeds to run without heat. When exhaust temperatures drop to approximately 120F, the contacts open to end the cycle.
