What to do if the error code F2.3 is displayed on the Mijia Air Conditioner?

If the Mijia Air Conditioner displays the error code F2.3, it indicates that the indoor unit pipe temperature sensing pack has triggered a failure protection mechanism. This means that the sensor responsible for detecting the temperature of the refrigerant in the indoor unit’s pipes is not functioning properly, which could affect the air conditioner’s cooling efficiency.
To resolve this issue, please refer to the following steps:
1. Turn off the air conditioner and disconnect it from the power source. Wait for approximately 3 to 5 minutes before reconnecting the power. Then, turn the device back on and check if the issue is resolved;
2. If the problem is not resolved through a power restart, it is recommended to apply for after-sales service for further inspection. A professional technician can diagnose the issue and provide the necessary repairs to restore normal operation.
