What is the fault of Gree air conditioner OE

The occurrence of OE in the air conditioner indicates that the external environment temperature is abnormal. This fault is set to ensure that the air conditioner does not work under abnormal temperature and power environment.

The failure reason of OE in Gree air conditioner

1. Incorrect use of air conditioner

For example, the heating mode can be turned on when the outdoor temperature is high in summer, and the cooling mode can be turned on when the outdoor temperature is low in winter. At this time, the user will be prompted that the external environment temperature is abnormal.

2. External DC fan failure

When the fan does not work normally, the temperature of the air conditioning motor may be too high. At this time, if the surrounding environment of the power supply is too high, it will be automatically protected. Replace the external DC fan.

3. Outdoor unit controller failure

This problem also occurs when the outdoor unit controller fails. Check whether the outdoor unit controller fails. If it is confirmed that the controller is faulty, replace the controller.
