What to do if the error code F1.1 is displayed on the Mijia Air Conditioner?

If the Mijia Air Conditioner displays the error code F1.1, it indicates a malfunction in the indoor unit temperature sensor. This sensor is responsible for detecting the room’s ambient temperature and ensuring the air conditioner adjusts its cooling output accordingly. A fault in this sensor can lead to incorrect temperature readings or improper cooling performance.
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.
