What to do if the error code E5 is displayed on the Mijia Air Conditioner?

The E5 error code on the Mijia Air Conditioner indicates that the compressor has triggered its overheat protection due to excessively high temperatures. To resolve this, you can turn off the air conditioner for about 10 minutes or longer, allowing the temperature to drop before restarting it.
If the air conditioner frequently displays the E5, you can check the following aspects:
1. Ensure that the outdoor unit is not too dirty. Please have a professional clean the outdoor unit to improve airflow and heat dissipation;
2. Check if the outdoor unit is exposed to direct sunlight, which can cause poor heat dissipation;
3. Make sure the outdoor unit is not installed inside a grill or enclosure, as this can also obstruct airflow and affect cooling efficiency. Remove any barriers if present;
4. Please have a professional check if the voltage is too low. If the voltage is low, a voltage stabilizer can be needed.
