What to do if the Mijia Air Conditioner displays error code P6?

The display of P6 on the Mijia Air Conditioner indicates overheating protection during refrigeration.
The troubleshooting steps are as follows:
1. If the voltage is unstable, wait for it to stabilize before attempting to turn on the unit. If the voltage remains unstable for an extended period, install a voltage stabilizer;
2. If the outdoor unit’s heat exchanger is dirty or clogged, clean it if conditions permit;
3. If the air intake and exhaust of the outdoor unit are obstructed, improve ventilation and heat dissipation conditions (such as removing grilles).
If the problem cannot be resolved by following the above methods, it is recommended to apply for after-sales service for an on-site inspection.
