In the hot summer or cold winter, air conditioning has become an indispensable appliance in our lives. However, when the air conditioner display does not light up and does not start, we may feel helpless and distressed. This article will first give possible answers, and then explain in detail the reasons for this situation and provide corresponding workarounds.
1. Possible causes
Power supply problem: The air conditioner is not connected to the power supply or the power cord is damaged, resulting in the failure to supply power normally.
Display failure: The air conditioner's display itself is faulty, such as a damaged display or loose connection lines.
Control board failure: The control board of the air conditioner is faulty, resulting in the inability to receive or send signals, making the air conditioner unable to start.
Remote control issues: The remote control battery is low or the remote control itself is malfunctioning, resulting in the inability to send a start signal to the air conditioner.
Protection function start: The protection function may be triggered inside the air conditioner for some reason, such as overload protection, voltage protection, etc., resulting in the air conditioner not starting.
Second, the solution
Check the power supply: First make sure the air conditioner is plugged in, and then check if the power cord is damaged. If the power cord is found to be damaged, it should be replaced with a new one.
Check the display: If the power supply is OK, but the display still doesn't light up, it may be a fault with the display itself. At this point, you can try gently tapping the display or replugging the connection cable of the display to see if it can get back to normal. If that still doesn't solve the problem, you may need to replace it with a new display.
Check the control board: If the display is normal, but the air conditioner still won't start, it may be that the control board is faulty. At this time, it is necessary to ask a professional to overhaul or replace the control board.
Check the remote: If none of the above methods solve the problem, you can try changing the remote battery or using a different remote control. If you still can't turn on the air conditioner, it may be that the remote control itself is faulty and you need to replace it with a new one.
Disarming the protection function: If the protection function is triggered inside the air conditioner and cannot be activated, you need to wait for a period of time for the air conditioner to automatically release the protection. If the protection cannot be lifted for a long time, it may be that there is a more serious fault inside the air conditioner and it needs to be repaired by professionals.
In addition to the solutions mentioned above, there are some other precautions that can help us avoid the problem that the air conditioner display does not light up and cannot start:
Regular maintenance: Regular maintenance and cleaning of the air conditioner can ensure that all components inside the air conditioner are in good working condition and reduce the occurrence of failures.
Proper use: When using the air conditioner, the correct operation method should be followed to avoid damage to the air conditioner caused by excessive use or improper use.
Timely maintenance: Once the air conditioner is found to be faulty or abnormal, professionals should be asked to repair and repair it in time to avoid further deterioration of the problem.
3. Case analysis
