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.
 [ DUAL ] Heater resistance 13 Ω (PIN 2-3) Heater
resistance 34 Ω (PIN 1-2)
- If resistance is infinity, replace Heater.
 [ SINGLE ] Heater resistance 10 Ω (PIN 1-3)
- 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
 Lamp resistance : ∞ Ω, (-) : BLU, (+) : WHT
