How to Repair a Kenmore Dryer's Internal Bias Thermostat

The internal bias thermostat in a Kenmore dryer is a thermostat part that controls the internal drying temperature, and is connected to the heating element in the rear of the dryer. If the dyer is getting too hot during a cycle, then the bias thermostat may not be stopping the dryer from reaching its peak temperature. You can remove the thermostat at any time to inspect it for damage and determine if the part needs to be fully replaced.
