There may be a variety of reasons involved in the heating of the Xiaomi air conditioner not responding, and below I will explain the possible reasons and related solutions in detail.
Temperature setting issues. First of all, make sure that the temperature of the air conditioner is set within the range where you need to heat it. Some air conditioners need to be set at a low temperature to start the heating mode, so check that the target temperature you set is suitable for heating operation.
Air conditioning mode settings. Double-check that the air conditioner is set to heating mode. Different air conditioner models may have different control methods, and some air conditioners need to be set manually in heating mode instead of switching through automatic mode. You can check the current mode of the air conditioner by using the remote control of the air conditioner or the setting button on the panel.
Air conditioner filter cleaning. If dust accumulates on the filter inside the air conditioner because it has not been cleaned for a long time, it may affect the normal operation of the air conditioner, including the heating function. Therefore, check and clean the filter of your air conditioner to ensure good air circulation.
The temperature sensor is faulty. The temperature sensor in the air conditioner is an important part of controlling the heating function, and if the sensor is damaged or malfunctioning, it may cause the heating function to not work properly. This situation may require a faulty part to be inspected and replaced by a professional service person.
Maintenance issues. Regular maintenance is the key to the normal operation of the air conditioner, if the air conditioner is not maintained for a long time, it may lead to damage to parts or circuit failure, which in turn affects the heating function. It is advisable to clean and maintain the air conditioner regularly and have it checked regularly by a professional.
Power connection issues. Make sure that the air conditioner socket and power line are connected properly, and that the power switch is turned on. Sometimes, the air conditioner may not turn on the heating mode due to a faulty socket or a problem with the power line.
Outdoor temperature limit. Some models of air conditioners cannot properly heat up when the outside temperature is too low. In the extremely cold environment of winter, some air conditioners may not be able to activate the heating function due to outdoor temperature restrictions. This is due to the protection mechanisms that the system is designed to avoid damaging the air conditioning unit under extreme conditions. If you find this to happen, it is recommended to wait for the outside temperature to rise up and try using the heating function again.
In summary, the failure of the Xiaomi air conditioner to heat may be caused by various reasons such as temperature setting, mode setting, filter cleaning, temperature sensor failure, maintenance, power connection, outdoor temperature limit, or air conditioning system failure.
