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 13 Ω (PIN 2-3)
Heater resistance 34 Ω (PIN 1-2)
- 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
