Component Electrical Testing
• Thermistor resistance 10K Ω @ 25°C 77°F
(2P-Blue & Red wire)
• 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.
