Error 11 — Suction temperature sensor abnormal

What does [11] mean?

The system detected that the suction temperature sensor is reading outside its expected range, or it's not sending a signal (open or short circuit).

• The sensor is not connected securely or correctly.
• The sensor itself has failed.
• The sensor's resistance has drifted over time.
• The main control board is not accurately reading the temperature signal.

Click steps to track your progress.

1. 1

   Ensure the sensor wiring is firmly and correctly connected.

2. 2

   Check if the sensor's resistance is within the expected range.

3. 3

   Verify that the temperature loop reading from the sensor is normal.

4. 4

   Replace the sensor if issues persist.
