What s going on when the air conditioner temperature light doesn t turn on?

The temperature light of the air conditioner is not lit, it may be that the temperature light of the air conditioner is broken, change the temperature indicator of the air conditioner, and it may be that the power supply of the outlet of the power supply is not good.

If the air conditioner temperature light does not turn on, it may be caused by a short circuit or open circuit in the light sensor signal above.

The reasons why the air conditioner indicator does not light up are power supply problems, damaged remote control, and sleep mode is set.

1. Power supply problems.

We need to check whether the power supply of the air conditioner has been plugged in, including outlets, plugs, etc., to ensure that the power supply is normal. If you make sure that the power supply is fine, then it is possible that the power supply line of the air conditioner is faulty, and it needs to be repaired by professionals.

2. The remote control is damaged.

Due to the damage of the remote control, we were unable to adjust the air conditioner in time and accurately, and the air conditioner light did not turn on. The solution is to try to replace the remote control battery to see if it is caused by a power failure, or use your mobile phone as a remote control to control the air conditioner.

3. Set the sleep mode.

In this mode, our indicator light will not light up, unless we turn off this mode after our air conditioner will light up normally, and secondly, another reason to rule out sleep mode is that we turn off the light, if we turn off the light, our air conditioner will not turn on the indicator light.

Precautions for the use of air conditioners

1. When using air conditioners in midsummer, the temperature difference between indoor and outdoor should not exceed 8. Do not blow directly at people when turning on the cold air, and wipe off the sweat before entering the air-conditioned room with heavy sweat.

2. In order to eliminate the smell of the dirty air in the sedan car, some people do not use ventilation, but use aromatics to deodorize, but they do not know that this will aggravate indoor pollution.

3. The environment of air conditioning is mostly closed, and it can be equipped with negative ion generators, air filters or germicidal lamps when conditions permit, and the filter screen should be cleaned in time according to the use of the condition. At the same time, it is necessary to open the window regularly for ventilation or leave some gaps in the window to facilitate the smooth flow of air, if the air conditioner is found to have peculiar smell or smoke, it should be stopped immediately for inspection.

There are many reasons why the air conditioner does not turn on, and the most common one is that the main power switch is faulty, or it is caused by the inability of indoor and outdoor units to communicate.

The solution to the air conditioner running light not lit:

1. If the main power switch fails, the indoor electric control board can be replaced.

2. Check whether the indoor and outdoor connection lines are correct according to the wiring diagram.

3. Replace the electrical control panel of the outdoor unit, if there is still a fault, check whether the wiring of the indoor unit is correct.

4. Replace the electrical control board of the indoor unit, if it is due to the poor communication of the transformer of the indoor unit (or outdoor unit), then the two-wire transformer of the primary winding can be replaced. If the electrical control board of the indoor unit is found to be defective, the machine fault can be eliminated by replacing the electric control board.

The most common reason why the air conditioner light does not light up is that the indicator light of the air conditioner may have been damaged, the more common reason is that the lamp beads in the diode of the air conditioner have some faults, and there is also a situation that can also cause the air conditioner light not to light up, it may be that the fuse tube of the power board is faulty, and it is best to find a professional maintenance personnel to repair it.

One is broken, and the other is turned off the lights.

When the air conditioner has a failure that the indicator light does not light up, the main thing should be to check whether the indicator light control drive signal is normal, whether the power supply of 105V is normal, and whether the indicator lamp itself is faulty.

The reasons why the air conditioner light doesn't turn on are as follows:

1. First of all, check whether the air conditioning blades have been opened, whether there is wind coming out, or whether the outdoor unit has the sound of running.

2. If it can't work normally, check whether the socket has electricity, followed by the power cord of the air conditioner, check whether the fuse is fused, and if it is fused, it needs to be replaced.

3. If the power indicator light was originally on and is now off, the internal unit insurance or transformer is damaged, and the general air conditioner will not be refrigerated and operated, but will be shut down directly;

4. It may be that the remote control is abnormal, you can try to replace the battery to see if it is caused by no power; or use the mobile phone as a remote control to control the air conditioner;

5. If the power supply voltage at home is too low, it will not be able to drive the air conditioner to start normally, and there will be an abnormal reaction that the air conditioner does not respond to the start and the display light does not turn on. In this case, it is best to ask after-sales maintenance personnel to come to test the voltage and install a voltage regulator. This answer is applicable to most brands of air conditioners such as Gree, Midea, and Haier.

There are several reasons why the air conditioner does not turn on: it may be that the display is accidentally turned off (but the air conditioner is coming out). Air switch in the home.

Trip. The fuse on the power strip is broken. The 7805,7812 on the board is likely to be broken.

The power supply is broken, and there is no air conditioning coming out. Extended information: Common sense of daily use and maintenance of air conditioners:

The temperature can be set appropriately, because when the air conditioner is cooling, if the indoor temperature is too different from the outdoor temperature, it is easy to make people get "air conditioning disease". It is recommended that the air conditioner be set at an acceptable temperature when used. When the air conditioner is cooling, the position of the wind deflector is adjusted to the horizontal direction, and the cooling effect will be better. Keep the air outlets smooth and don't pile up bulky furniture to block air circulation.

Unplug the air conditioner when not in use for a long time, as the standby state will also consume power. Do not place heavy objects on the outdoor unit. There should be no shelter around the outdoor unit.

Before restarting the machine, carefully check whether the drain pipe of the indoor unit is blocked by debris to prevent the phenomenon of stagnant water backfilling. Use a separate socket and cannot be shared with other electrical appliances; Do not change the operating status of the air conditioner while the machine is running. The indoor air inlet filter should be cleaned every 15 days, and the outdoor unit should be dusted regularly.

When the air conditioner is not in use or in case of thunderstorms, the power supply of the air conditioner should be cut off in time to avoid machine failure caused by power connection.

According to the phenomenon analysis, the fault is generally caused by the inability of indoor and outdoor units to communicate. The main reasons and maintenance methods are as follows:

1. Check whether the indoor and outdoor connection lines are correct according to the wiring diagram.

2. Change the outdoor electrical control board, if the fault still exists, check whether the wiring of the indoor unit is correct.

3. Change the indoor electromechanical control board. If the communication is bad due to the replacement of the transformer of the indoor unit (or outdoor unit), the two wires of the primary winding of the transformer can be swapped. The machine was inspected as having a poor indoor electromechanical control board. Machine troubleshooting after replacing the electric control board.

1. Turn off the display (but the air conditioner is air-conditioned).

2. The air switch at home tripped.

3. The fuse tube on the power strip is broken.

4. The 7805 and 7812 on the circuit board are likely to be broken.

5. The power supply is broken (2-5) and there is no air conditioner coming out.

2.There was some malfunction in the lamp beads inside the diode of the air conditioner.

3.It is possible that the fuse of the power strip is faulty, and it is best to find a professional maintenance personnel to repair it.

Then it is very likely that the transformer in the internal machine is broken, it is to supply power to the computer board, of course, the display screen is also powered by it, you can see if it is good.
