There are many reasons why the air conditioner is blowing but not cooling. How to troubleshoot?
. Ventilation issues: First, ensure that the indoor and outdoor units are clean and ventilated smoothly. This is also the most basic condition to ensure the normal operation of the air conditioner, including clean indoor filters and outdoor unit fins
. It is recommended to clean it at least once a year based on usage.
, the leakage of refrigerant in the refrigeration system leads to poor cooling effect, thermal protection caused by the increase in exhaust temperature, etc.,.
The compressor, fan, and capacitor are damaged due to damage to the circuits such as compressor protection or failure to work.
, poor refrigeration, compressor protection and other faults caused by blockage of the refrigeration system.
, Improper installation or poor working environment, the outdoor unit faces the sun, causing the temperature of the outdoor unit to be too high. The outdoor unit exceeds the normal working environment, etc.,,
, The power supply voltage is low or the power supply line is faulty
Compression There is condensation on the suction pipe of the compressor. The pump casing at the intake pipe is cool but the pump casing body is hot. The exhaust pipe temperature is slightly higher. The refrigerant is moderate. There is no condensation on the suction pipe of the compressor. The exhaust temperature is not too hot, which means there is too little refrigerant. . However, if an expansion valve is used, it should be checked whether the valve is opened too small, causing condensation on the suction pipe of the compressor. If more than half of the pump casing is covered with condensation, it means that the amount of refrigerant is too much. If an expansion valve is used, it may also be caused by the valve opening too large. For a rotary compressor, normally the pump casing is filled with high-temperature and high-pressure gas, and the pump casing and exhaust pipe are always hot (even hot to the touch) without condensation.
