What is the reason why Daikin central air conditioning does not cool?

There are several reasons why the central air conditioner does not cool:

One: the indoor unit or outdoor unit is not running.

When the central air conditioner is not cooled, it is first necessary to check whether the air conditioner is operating normally, including indoor units and outdoor units, especially the compressors of outdoor units. As long as one of them doesn't work properly, it must be repaired by professionals.

Two: the temperature is not adjusted properly or the doors and windows are not closed properly.

Some users often get the temperature adjustment switch wrong because they lack common sense of central air conditioning. In addition, if the doors and windows of the room are not properly closed, the central air conditioner will not cool. No matter what air conditioner is running normally, the room is required to be closed. Therefore, when the central air conditioner is not cooled, it is necessary to check whether the doors and windows of the room are closed.

Three: There is something wrong with the power supply or voltage.

The problem of power supply or voltage is more common in summer, because the electricity consumption in hot summer is relatively large, which seriously exceeds the electricity load, which will lead to the central air conditioning not cooling. In this case, there is no better way. At most, it is to negotiate with the local property to increase the rated power, and then buy a better regulator.

Four: The air filter is blocked.

Due to the long-term use of the air conditioner, the filter screen is blocked and not cleaned regularly, and the sediment accumulates over time, which eventually leads to the central air conditioner being unable to cool. It is recommended to maintain the central air conditioner regularly.

Five: There is something wrong with the wiring of the internal and external machines.

The wiring between internal and external machines is also one of the frequent points of failure. If this failure occurs, it is recommended to check whether the wire connector is welded and wrap it with waterproof and insulating tape.

Six: the sensor is open or short-circuited.

The temperature sensor of the central air conditioner is short-circuited or appears short-circuited, the plug-in is in poor contact, and the socket is out of welding. The reason of short circuit is that the resistance value is reduced to below 200 Ω, and the leakage of circuit board or components will cause the central air conditioner not to cool. At this time, the pressure protection is small, so it is recommended to check whether the sensor is in good condition.
