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 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
 Belt Cut-off S/W
- Lever open: Resistance value < 1Ω
- Lever push: Resistance value : ∞ Ω
 Vent Sensing - Thermistor Resistance
238.23K Ω @ 25 ℃ 77℉
