[ Electric ]
• Thermistor resistance 10K Ω @ 25°C (77°F)
• Thermostat 1 resistance < 1Ω
• Thermostat 3 resistance < 1Ω
- If resistance is infinite, replace thermostat 3.
• Thermostat 2 resistance < 1Ω
- If resistance is infinite, replace thermostat 2.
HEATER
• [DUAL] Heater resistance 13Ω (PIN 2-3) Heater.
• Resistance 34Ω (PIN 1-2)
- If resistance is infinite, replace heater.
• [SINGLE] Heater resistance 10Ω (PIN 1-3)
- If resistance is infinite, replace heater.
• Measure resistance on 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
