P7 — Outdoor IGBT temperature sensor error

What does P7 mean?

There is an error with the temperature sensor monitoring the Insulated Gate Bipolar Transistor (IGBT) in the outdoor unit. The IGBT is a critical component for power switching.

• Faulty IGBT temperature sensor
• Overheating of the IGBT module
• Poor electrical connection to the sensor

Click steps to track your progress.

1. 1

   Ensure the outdoor unit has adequate ventilation and is not overheating.

2. 2

   Check the electrical connections to the IGBT temperature sensor.

3. 3

   If the sensor reading is abnormal or the IGBT is overheating, professional servicing is required.
