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 Belt Cut-off S/W - Lever open: Resistance value < 1Ω - Lever push: Resistance value : ∞ Ω  Thermostat 3 resistance < 1Ω - If resistance is infinity, replace thermostat 3.  Thermostat 2 resistance < 1Ω - If resistance is infinity, replace thermostat 2.  [DUAL] Heater resistance 13 Ω (PIN 2-3) Heater resistance 34 Ω (PIN 1-2) - If resistance is infinity, replace Heater.  [SINGLE] Heater resistance 10 Ω (PIN 1-3) - If resistance is infinity, replace Heater. 1 2 3  Measure resistance of the following terminal 1) Door switch : off Terminal : "COM" - "NC" (1-3) < 1Ω Terminal : "COM" - "NO" (1-2) : ∞ Ω 2) Door switch : On Terminal : "COM" - "NC" (1-3) : ∞ Ω Terminal : "COM" - "NO" (1-2) < 1Ω  Lamp resistance BLU, (+) : WHT  Motor (Electronic & GAS) Contacts Function 1M 2M 3M 5M 6M Start Run  = Contact closed Centrifugal Switch (Motor) 2.88Ω between Pin# 3 and 4 3.5Ω between Pin# 4 and 5 7 Technical_information-03382A_EN_131209.indd 7 2013-12-09 �� 5:37:33
