Component Testing Procedures

WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to dryer before servicing, unless testing requires power.

Component Electrical Testing (with ohmmeter)	● Belt Cut-off S/W
● Thermistor resistance 10K Ω @ 25°C 77°F	- Lever open: Resistance value < 1Ω
(2P-Blue & Red wire)	- Lever push: Resistance value
● Thermostat 1 resistance < 1Ω (White &
Yellow wire)

●Thermostat 3 resistance < 1Ω (Red &

Black wire)

-If resistance is infinity, replace thermostat 3.

●Thermostat 2 resistance < 1Ω (Blue &

Black wire)

-If resistance is infinity, replace thermostat 2.

●Heater resistance 10 Ω (Blue & Blue wire) -If resistance is infinity, replace Heater.

●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

●Lamp resistance 80~100 Ω (Violet & gray)

●Motor (Electronic & GAS) Contacts

Function 1M 2M 3M 5M 6M

= Contact closed

Centrifugal Switch (Motor)

2.88Ω between Pin# 3 and 4

3.5Ω between Pin# 4 and 5
