Component Testing Procedures
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)
• Thermistor resistance 10K Ω @ 25°C 77°F PTC
(2P-Blue & Red wire)
• Thermostat 1 resistance < 1Ω (White & Yellow wire)
THERMOSTAT 1
185°F, 85°C, 25A
thermal cut-off
• 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.

thermal cut-off
• Measure resistance of the following terminal
1) Door switch button : out
Terminal : "COM" - "NC" (1-3) < 1Ω
Terminal : "COM" - "NO" (1-2) : ∞ Ω
2) Door switch button : in
Terminal : "COM" - "NC" (1-3) : ∞ Ω
Terminal : "COM" - "NO" (1-2) < 1Ω
