Under normal circumstances, air conditioning can mainly help us to adjust the indoor temperature, our room temperature control in the human body feels more comfortable conditions. Air conditioning can also control our humidity, the air is generally too dry or humid will let us feel very uncomfortable, through the effective regulation of air conditioning, the content of water vapor in the air is controlled under the condition of higher comfort of human body. However, sometimes, air conditioning for a long time or other reasons, it may not work outside the machine, this time how to do?
First, the remote control mode is incorrect
Check whether the remote control is set to refrigeration mode. Using the air conditioner remote control, adjust the mode to display “Refrigeration” or “Snowflake” state, and set the temperature to 26 degrees or below.
Two, the power supply problem
Check whether the outdoor unit (including the outdoor unit fan and compressor) generates sound. If the outdoor fan is running, the control circuit is normal. Check whether the compressor starts. If the compressor does not start, check whether the power supply is normal.
Three, the reason of voltage
There are many reasons why the voltage is not enough. If the air conditioner can not be turned on, it is necessary to check whether there is electricity or whether the voltage reaches the rated voltage. If it is not the cause of low power, please check whether the indoor and outdoor machine is connected, whether the wire is aging, and whether the indoor motherboard is connected correctly. Otherwise, replace the internal motherboard.
Four, a long time without maintenance
The air conditioning for a long time will not maintain the air conditioning outdoor unit does not turn, the specific air conditioning outdoor unit does not turn the reason analysis, in structure, may be the screw and wind wheel lock part loose; Improper alignment of motor and wind wheel; Due to the problem of injection molding process assurance, plastic parts have squeaky sound, air guide and connecting rod mechanism belong to plastic parts, air guide, stepping motor and connecting rod mechanism structure parts transmission performance is affected, will also cause the indoor unit does not run.
5. The ambient temperature is too high, resulting in system protection
If the ambient temperature is too high, the direct sun does not shade objects, or the outdoor unit is poorly ventilated and shielded by a net cover or wall in front of the outdoor unit, the air conditioner heat cannot be blown out. If the temperature is too high, the compressor automatically starts to protect the air conditioner and stops working to prevent the compressor from being damaged.
6. Ac contactor failure
Power on the AC contactor. Use a multimeter to measure the outgoing end of the AC contactor and check whether the voltage reaches 380V. If no, the AC contactor is damaged and needs to be replaced with a new one.
In summer, air conditioning for refrigeration, winter, air conditioning for heating. In fact, it is the process of freon liquefaction and gasification, this process, let us all keep in a comfortable environment, improve work efficiency, warm in winter and cool in summer, said is this principle. When the air conditioning machine can not run because of obstacles, do not worry too much, as long as the specific problem specific analysis, for the main causes of analysis and solution, it can make the machine restart normal operation.
