What's the matter with the air conditioner not heating? Maybe it's something wrong with this place

4hw.com.cn: it's hard to avoid some small problems when the air conditioner has been used for a long time. If the refrigeration of the air conditioner is normal but the heating doesn't work, what's the matter? It may be the following reasons.

How is air conditioning refrigeration not heating

1. First of all, you need to determine whether the air conditioner is a dual system, that is, whether the air conditioner has both refrigeration and heating. If the air conditioner is a single refrigeration air conditioner, it will not have heating function.

2. Whether the mode is set correctly, and heating cannot be carried out in summer or when the ambient temperature is higher than the set temperature. If heating is to be carried out, heating can only be carried out in winter.

3. If your air conditioner is a dual system, it can cool and heat, and your setting is correct. At this time, the refrigeration is normal but can not heat, it means that there is something wrong with the four-way reversing valve of the air conditioner. For some reason, the four-way steering valve can not turn normally, so you need to find professional maintenance personnel to repair or replace it, and check whether the coil of the four-way valve is damaged Whether the coil power supply is normal.

What are the reasons for air conditioning not cooling

1. Lack of freon, also known as lack of snow, is generally caused by leakage of air conditioning system.

2. The power supply voltage is small. If the family voltage is too small, the cooling effect of the air conditioner will become worse. If it is lower than a certain value, the air conditioner will stop.

3. If the power of the air conditioner is too small, although the air conditioner has refrigeration, its refrigeration efficiency is too poor to meet the cooling demand of the room, so it will feel that the room is not cool.

4. If the filter screen of the air conditioner is not washed for a long time, the blockage of the filter screen will lead to the decrease of the air blowing volume, which will lead to the deterioration of the refrigeration effect.

How does the air conditioner turn on for a while without refrigeration

1. Now this phenomenon is likely to be outdoor compressor protection. Generally, the condenser of outdoor unit is dirty and blocked, which leads to poor heat dissipation. It's time to clean the air conditioner.

2. It is also possible that the capacity of the Compressor Capacitor attenuates the over-current, and the compressor capacitor can be replaced. There is also the low speed of the outdoor fan, which is also the fan capacitance attenuation fault, which needs to be replaced.
