If the Mijia Air Conditioner displays the error code P2.5, it indicates that the frequency of the load protection is limited or reduced.
You can troubleshoot it by the following steps:
1. The voltage is unstable. Wait for the voltage to stabilize before turning it on. If the voltage is unstable for a long time, please install a voltage regulator;
2. The outdoor unit heat exchanger is dirty and blocked. If conditions permit, please clean the heat exchanger;
3. The outdoor unit does not blow air smoothly. Improve ventilation conditions and heat dissipation environment (such as removing the grille).
4. If the air conditioner displays a protection code in a high-temperature environment and the device can operate normally, it is normal. And it will automatically disappear when the temperature drops;
5. The indoor unit filter is too dirty and needs to be cleaned.
If the above steps do not resolve the issue, please apply for the after-sales service center for inspection.
