Error code: E9: T3 high temperature protection

Reasons and solutions:

1. Outdoor air circulation is bad. Check if any obstacle blocks the air circulation.

2. Condenser is too dirty. Wash the condenser.

Refer to the Installation/ Operation manual.

4. Outdoor fan is not running or running speed is too low. Check the fan.

The fan blade should be rotated smoothly and the wiring is not loose.
