5106 (1216) Temperature sensor fault - HIC circuit outlet temperature (TH6)

What does 5106 (1216) mean?

This error pertains to the temperature sensor (TH6) that monitors the HIC circuit outlet. The sensor might be short-circuited or open, leading to inaccurate temperature readings for this critical part of the system.

• Pinched or damaged lead wire for the TH6 thermistor.
• Loose or disconnected connector for TH6.
• Short detection (TH6 reading 70°C [158°F] or above).
• Open detection (TH6 reading -40°C [-40°F] or below).
• Control board malfunction if sensor readings are far from actual temperature.

Click steps to track your progress.

1. 1

   Turn off the power to the unit at the circuit breaker.

2. 2

   Visually inspect the wiring for the TH6 temperature sensor for any signs of pinching, damage, or wear on the wire coating.

3. 3

   Ensure the TH6 sensor connector is securely attached.

4. 4

   If you have an LED monitor, check the intake temperature of the sensor; if it's far from the actual temperature, note this.

5. 5

   Restore power. If the problem recurs, contact a service professional to check the thermistor resistance and potentially replace the control board.
