What to do if the Mijia Air Conditioner Eco EGAT Label No.5 with 1 Star 12000BTU is not cooling?

Question

Accepted Answer

If the Mijia Air Conditioner Eco EGAT Label No.5 with 1 Star 12000BTU is not cooling, please follow these troubleshooting steps:
1. Check the air conditioner settings, turn on cooling mode, and set the fan speed to the highest.
2. After turning on the air conditioner for 5 minutes, place your hand near the air outlet to feel if cold air is blowing out. If cold air is blowing, the air conditioner is working normally. However, it takes time for the cooling to lower the room temperature. Turn on the air conditioner and continue to observe for up to one hour. If the room temperature keeps decreasing during this period, it indicates normal operation. When the air conditioner is blowing cold air, after one hour of operation, place a thermometer at the air outlet for 5 to 10 minutes. If the measured temperature is below 10 °C, this is considered normal.
3. Check whether the filter is dirty or blocked, as a clogged filter can reduce airflow and affect cooling performance. Clean the filter if necessary and retry.
4. Make sure doors and windows are properly closed, since open spaces or heat sources can significantly reduce cooling efficiency.
5. Verify that the outdoor unit is operating normally and not blocked by dust, debris, or poor ventilation, as this may affect heat dissipation and cooling performance.
6. Ensure the installation environment meets requirements, as improper installation (such as poor airflow circulation or direct sunlight exposure) may lead to weak cooling.
7. If the above steps do not resolve the issue, it is recommended to contact the local after-sales service.
