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.
Measure resistance of the following terminal

1) Door switch : Off
Terminal : "COM" - "NC" (1-3) : <1Ω
Terminal : "COM" - "NO" (1-2) : ∞ Ω
2) Door switch : On
Terminal : "COM" - "NC" (1-3) : ∞ Ω
Terminal : "COM" - "NO" (1-2) < 1Ω
