TROUBLE SHOOTING
To avoid risk of electrical shock, personal injury or death; disconnect power to dryer before
servicing, unless testing requires power.
COMPONENT TESTING PROCEDURES
Component Electrical Testing (with ohmmeter)
Thermistor resistance 10K Ω @ 25°C 77°F

Thermostat 1 resistance < 1Ω

Thermostat 3 resistance < 1Ω

- If resistance is infinity, replace thermostat 3.
Thermostat 2 resistance < 1Ω

- If resistance is infinity, replace thermostat 2.
Heater resistance 10 Ω

- If resistance is infinity, replace Heater.
