COMPONENT TESTING PROCEDURES
Component Electrical Testing (with ohmmeter)
● Thermistor resistance 10K Ω @ 25°C 77°F
(2P-Blue & Red wire)
● Thermostat 1 resistance < 1Ω (White &
Yellow wire)
● Belt Cut-off S/W
- Lever open: Resistance value < 1Ω
- Lever push: Resistance value
● Thermostat 3 resistance < 1Ω (Red &
Black wire)
-If resistance is innity, replace thermostat 3.
● Thermostat 2 resistance < 1Ω (Blue &
Black wire)
-If resistance is innity, replace thermostat 2.
● Heater resistance 10 Ω (Blue & Blue wire)
-If resistance is innity, replace Heater.
● Lamp resistance 80~100 Ω
(Violet & gray)

● Measure resistance of the following terminal
1) Door switch knob: open
Terminal : “COM” - “NC” (1-3) : ∞ Ω
Terminal : “COM” - “NO” (1-2) < 1Ω
2) Door switch push: On
Terminal : “COM” - “NC” (1-3) : ∞ Ω
Terminal : “COM” - “NO” (1-2) < 1Ω
Centrifugal Switch (Motor)
2.88Ω between
Pin# 3 and 4
3.5Ω between
Pin# 4 and 5
WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to dryer

before servicing, unless testing requires power.

TROUBLE SHOOTING
● Motor (Electronic & GAS)
