The continuous flashing of the air conditioning display screen may be caused by various reasons. The following are some possible reasons and corresponding solutions: 1. Power problem
1. Poor contact of power cord: Check if the power cord is securely plugged in to ensure it is not loose or damaged. If there is a problem with the power cord, replace it with a new one in a timely manner.
2. Unstable power supply voltage: Check if the power supply voltage is stable. If the voltage fluctuates greatly, it may affect the normal operation of the air conditioner. You can try using a voltage regulator or contact the power company to solve the voltage problem.
3. Power switch malfunction: If the power switch is not completely turned off or damaged, it may also cause the display screen to flicker. At this point, it is necessary to completely turn off the power switch before turning it back on, or replace the power switch. 2、 Display Exception
1. Display board malfunction: If the display board of the air conditioner malfunctions, it may cause the display screen to flash. At this point, it is necessary to have a professional check whether the display board is damaged. If it is damaged, the display board needs to be replaced.
2. Circuit board cable detachment: Check if the air conditioning circuit board cable is loose or detached. If a problem is found, the cable can be reinstalled. 3、 Hardware malfunction
1. Internal hardware failure: Malfunctions in the internal hardware of the air conditioner, such as the main control board and display screen control circuit board, may also cause the display screen to flicker. This situation requires professional inspection and maintenance.
2. Cooling system malfunction: If the cooling system of the air conditioner malfunctions, such as damaged cooling fans or blocked cooling fins, it may affect the normal operation of the air conditioner and cause the display screen to flicker. At this point, it is necessary to clean the cooling system or replace damaged components. 4、 Setting and running issues
1. Incorrect air conditioning settings: Check if the air conditioning settings are correct, such as whether the remote control is set to the correct mode (cooling, heating, air supply, etc.). If the settings are incorrect, it may cause the air conditioner to malfunction, resulting in the display screen flashing. At this point, it is necessary to change the air conditioning mode to ensure its normal operation.
2. Excessive dust on the filter screen: If the air conditioner filter screen is filled with dust, it will affect air circulation and prevent the air conditioner from working properly. At this point, you can try cleaning the filter to restore the air conditioning to normal flow.
3. Current overload: When the current is overloaded, it will cause the air conditioning running light to flash. For example, if the voltage at home is too high, it can cause the air conditioner to overload. At this time, the air conditioner will activate its self-protection system, and the indicator light will continue to flash, accompanied by the phenomenon of turning on and off. At this point, you can check the home circuit and turn off other high-power appliances. If it cannot be resolved, please contact the local power department for inquiries.
4. Air conditioning defrosting: In winter, the lights will flash continuously during air conditioning defrosting, which is a normal phenomenon. 5、 Other faults
1. Compressor and cooling fan malfunction: When the control contactors of the compressor and cooling fan are damaged, the air conditioning display screen may flash. This situation requires a professional technician to repair it.
2. Insufficient refrigerant: Insufficient refrigerant may also cause the air conditioning display screen to flash. At this point, refrigerant needs to be added to solve the problem.
3. Air conditioner overheating protection: If the air conditioner overheats, it may trigger the overheating protection mechanism, causing the display screen to flash. At this point, you can turn off the device for an hour and then try turning it back on.
If none of the above methods can solve the problem, it is recommended to contact professional air conditioning maintenance personnel for inspection and repair. Before maintenance, please make sure to turn off the air conditioning power to ensure safety.
