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 : 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
Belt Cut-off S/W
- Lever open: Resistance value < 1Ω
- Lever push: Resistance value : ∞ Ω
Lamp resistance 80~100 Ω (Blue & White)
Motor (Electronic & GAS)
Contacts
= Contact closed
Centrifugal Switch (Motor)
2.88Ω between
Pin# 3 and 4
3.5Ω between
Pin# 4 and 5
