TROUBLE SHOOTING

WARNING

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 innity, replace thermostat 3.



Thermostat 2 resistance < 1Ω

- If resistance is innity, replace thermostat 2.



Heater resistance 10 Ω

- If resistance is innity, replace Heater.



Measure resistance of the following terminal

1) Door switch : open

Terminal : “COM” - “NC” (1-3) < 1Ω

Terminal : “COM” - “NO” (1-2) : ∞ Ω

2) Door switch push: On

Terminal : “COM” - “NC” (1-3) : ∞ Ω

Terminal : “COM” - “NO” (1-2) < 1Ω
