Why can’t the air conditioner start? What should I do if the air conditioner cannot be turned on?
It is inevitable that the air conditioner will encounter some problems during the use of it, and these are all things that we need to solve. What happens if the air conditioner cannot be turned on but the remote control displays?
1. The air conditioner cannot be turned on but the remote control displays it. It is likely that the outdoor unit is in a voltage protected state.
At this time, you can cut off the power supply first, then open the cover of the indoor unit, find the emergency switch on the right side and poke it a few times, and then connect the power supply. This will basically be handled.
You can also check the air switch to see if it was caused by tripping. If it tripped, just pull it back.
2. The air conditioner cannot be turned on but the remote control displays it. It is also very likely that we pressed the lock button function of the air conditioner and encountered this problem.
The solution is also very simple. We just need to press and hold the unlock function button on the air conditioner remote control to use the air conditioner normally.
Summary: There are many reasons why the air conditioner cannot be turned on. Be patient and carefully check which part of the reason is. If you really can’t handle it, it is recommended to ask a professional maintenance staff to check it.
2. What’s wrong with the air conditioner not turning on?
1. The battery is low
There is garbled code or freeze on the air conditioner screen. You can press the reset button to cancel it. It may also be caused by insufficient battery power.
The temperature is not displayed. In the air supply or automatic mode, the temperature is not displayed. It may be caused by the receiving head being broken or being affected by moisture and unable to work normally. The transmission of remote control signals needs to be checked.
Use the digital camera to aim at the launch port and press any button to see if there is an infrared signal, the mode is incorrect, or the temperature setting does not meet the conditions for booting.
When cooling, the set temperature should be lower than the indoor temperature. When heating, the set temperature should be greater than the indoor temperature.
The low battery power of the air conditioner can also lead to short remote control distances or inability to remotely control. It is recommended to remove the battery when the air conditioner is not in use and install it when it is in use.
2. Power supply reasons
If the power supply of the air conditioner is not connected properly, or if the power is not connected, the air conditioner will not be turned on. Poor contact with the power supply wire socket, thin diameter or aging of the power supply wire, and low power supply voltage are all reasons.
3. Protection function
In order to protect the life of the press, protection circuits are designed in the control circuits of computer boards of many air conditioners. The press starts after a delay of minutes. Heating cold air prevents air conditioning from working, when the indoor unit coil temperature is lower than a certain value.
The computer program of the air conditioner is chaotic, making the machine unable to perform the scheduled work. Functional lock protection, some brands or models have child lock function. If you are in lock mode and cannot perform any operation, you can cancel it according to the instructions.
3. How to clean the filter when hanging up the air conditioner
1. First disconnect the power supply of the air conditioner and open the cover of the radiator.
2. Take out the filter on the radiator and clean it.
3. The next step is to clean the heat sink. The dust on the heat sink is more than the dust on the filter.
5. Remove the cover on the radiator and prepare the spray device (try to use a cleaning spray specially used for cleaning air conditioners). If you don’t have it, you can make one yourself.
6. Find a mineral water bottle, make a few small holes in the bottle cap, fill the bottle with water, add detergent, and shake well for use.
7. First wipe off the dust on the surface of the air conditioner with a rag, and then use spray to clean the radiator from top to bottom.
8. After cleaning, install the filter and turn on the refrigeration to flow out the unclean things in the radiator.
