Haier air conditioner running light turns on and doesn t light up after a few seconds, what s going

The reasons why the air conditioner running light does not light up may be:1Abnormal power supply voltage makes it difficult to start the compressor and protect, 2

The air conditioner self-test fails and stops running, 3If there is an error in the operation control of the computer board, the computer board needs to be replaced, 4Temperature sensor overload information error, 5

Loose power wiring, poor contact, 6The starter capacitor or compressor starter coil burns out. There are many other possibilities, and it is recommended to check it out with a professional maintenance person.

An air conditioner is an air conditioner. Refers to the process of adjusting and controlling parameters such as temperature, humidity, cleanliness, speed of ambient air in building structures by artificial means.

Generally, it includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal device and other major parts and other auxiliary equipment. It mainly includes pumps, fans and piping systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically process the air and temperature to make the air parameters of the target environment meet the requirements.

If you buy it without a display, the air conditioner will automatically standby after it reaches the temperature you set, the outdoor unit will not work, the indoor unit will send natural wind, and the indicator light will automatically turn off.

It is estimated that the power supply is protected, it may be that the voltage is low, it is recommended that you try it when there are few people, if it still doesn't work, just find after-sales service.

The air conditioner has a sleep mode, and the remote control also has a display setting, if the cooling is normal, it may be that you have pressed the sleep mode or pressed the display setting key of the remote control.

It could be that you turned off the light function!

That's a glitch**! Find after-sales service!

When the air conditioner is turned on, the running light will not be on for a while, and then the external unit will still be moving? If the external unit does not move, there are two reasons, one is to reach the set temperature, and the other is that the external unit cannot be protected when it is started.

The reasons and solutions for Haier air conditioners not to turn on, and the running lights not to light up and not to refrigerate are as follows:

1. The compressor has no refrigerant, add refrigerant.

3. If the compressor is damaged, replace the compressor.

4. If the thermostat is broken, replace the thermostat.

5. The temperature sensor is broken, replace the sensor.

6. If the sensor position is not in place, re-install the sensor.

Precautions for the use of Haier air conditioner when it is turned on:1. Always check whether the contact between the electrical plug and the socket of the air conditioner is good, if it is found that the power supply lead wire or plug is hot when the air conditioner is running, this may be because the electrical wiring is too thin or the plug and socket are not in good contact, and corresponding measures should be taken according to the situation.

2. Open the window for ventilation for a quarter of an hour at the same time every day, and ventilate for more time when you use it for the first time, so that the bacteria, mold and mites stored in the air conditioner can be distributed as much as possible.

The air conditioner does not respond when it is turned on, and the air conditioner does not run and the fault is detected.

1) Whether the power plug is plugged into the outlet.

2) Whether it is run on a regular basis.

3) Whether there is a power outage or a blown fuse.

4) Whether the dry battery of the remote control has run out.

5) Whether the voltage is higher than 242 volts, or lower than 198 volts.

6) When the refrigeration is running, whether the set temperature is higher than the room temperature.

7) When heating, whether the set temperature is lower than room temperature.

For details, please call us or make an appointment for maintenance.

1. The compressor has no refrigerant, add refrigerant.

3. If the compressor is damaged, replace the compressor.

4. If the thermostat is broken, replace the thermostat.

5. The temperature sensor is broken, replace the sensor.

6. If the sensor position is not in place, re-install the sensor.

How to run without booting, you check the plug first, and then check the remote control, if there is no problem, then the machine is faulty, or find a professional to repair it for you.

Reason:

1. The air conditioning mode is set on ventilation. Just adjust the mode.

2. The starting capacitor of the external compressor is broken. The starting capacitor needs to be serviced.

3. The air-conditioning and refrigeration system lacks refrigerant (freon). Refrigerant needs to be added.

The choice of the number of horsesThe output cooling capacity (heat) of the air conditioner should correspond to the area used, due to the difference in the room conditions and regional climate of the air conditioner, as well as the plan for extreme weather, the air conditioner should be bought big or small.

There are many factors that will affect the temperature effect of the air conditioner, among which the most important floor, west sun, west window, house type, etc., so how to accurately calculate the amount of air conditioning power required in the room?

First of all, the cooling capacity required per square meter is set at 150W;

If the top floor and the west sun occupy one of them, it will be calculated according to 200w per square meter;

If there is a west window or both the top floor and the west sun, at least 250w per square meter;

There are both west windows and top floors, at least 300W per square meter;

Workaround:

When the power light can light up after powering on, it means that the power supply has been connected to the computer board. On the Gree air conditioning control system, if there is a power input, there will be a power output, and the so-called output is output to various components, including compressors, fans and other refrigeration components.

At the same time, as a highly intelligent electrical appliance, its computer board is also equipped with a feedback device. That is, when the computer board supplies power to the working components, after the working components work normally, this working situation will be fed back to the computer board at the same time.

When the computer supplies power to the compressor, after the compressor runs normally, the compressor is fed back to the computer board at the same time, and then the computer board will give a small direct current to the running light to make the running light on. If the running light cannot be lit up, you need to check whether the power supply line of the computer board to the compressor and the compressor itself are faulty, and you also need to check whether the feedback signal returns to the computer board normally, and secondly, you need to check whether the running light circuit is normal.

Therefore, when the running light of the Gree air conditioner is not lit, it needs to be checked including a series of conditions, and cannot be unilaterally analyzed.

The first aspect is the voltage problem, the second aspect is that the fuse of the air conditioner is burned out, and the third aspect may be that the resistance of the external unit is broken, and you can see it when you open the shell. Hope it helps.

There are mainly these reasons:

a. The external ambient temperature is high, and the indoor personnel are more than Gree air conditioners working at full load.

b. The power supply voltage is too low, which causes the Gree air conditioner to be difficult to start, and then stops or the fuse blows after starting, so it is recommended that the user install a power regulator.

c. The air outlet of the air outlet is not large if the temperature cannot be lowered in the strong cold block room, which is because the air filter has too much dust, and the filter is cleaned.

d. Improper adjustment of the thermostat.

e. The installation position of Gree air conditioner is not good, which will lead to uneven indoor temperature or poor refrigeration effect.

Are you referring to the lights flickering? If it is flashing, you need the brand and model of the air conditioner to know that it is a failure.

If the power is cut off, and there is a "beep" sound every time the light is on, please check the electrical circuit at home** for poor contact, especially at the safety or security guard. If the contact is poor, the lights in the home will suddenly dim when the air conditioner lights go out.

There is also the possibility that the emergency switch is short-circuited by moisture.

Most likely, it is a poor contact with the power supply, check it.

1. It may be that the automatic mode is set, and the set temperature is close to the room temperature, and there is no cold air blowing out until the set temperature, resulting in a feeling of not cooling.

2. The voltage is abnormal and unstable. Resulting in compressor overcurrent protection. The solution can be to add a voltage regulator.

3. The temperature of the indoor coil is too high, resulting in protective shutdown. When the indoor temperature is 26 degrees Celsius and the outdoor temperature is above 20 degrees, the air conditioner cannot heat normally, which is easy to cause protection.

4. The failure of the indoor fan causes no blowing and protects the shutdown. If the outdoor fan fails, causing serious frosting, defrost is carried out, and the indoor air prevention function is entered.

Probably self-preservation, you see if the fan outside is too dirty.

Hello, the most likely cause is the phenomenon of the compressor protector tripping. Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high. Causes and elimination of high pressure and overheating:

Too much refrigerant. Reduce the refrigeration dose appropriately. Poor heat dissipation.

Check the condenser pipe for dirt and dirt and clean the condenser. The piping system is clogged. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

Dust and fouling in the evaporator or strainer. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned. Fluoride deficiency is also possible.

When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip. The problem with the circuit is that the control circuit board is faulty.

The temperature sensor is overloaded and the information is incorrect. The power wiring is loose and the contact is poor. The starter capacitor or compressor starter coil burns out.

Hello, I am repairing household appliances, this needs to be checked, only to know, you have to see if the internal and external units are operating normally, and then insist on the lights flashing and flashing, take a look, whether the internal and external units are working normally, and then look at the situation, and then check step by step, step by step, there may be system protection, personal opinions, I hope you can smile, I hope it can help you.

Hello, the compressor starts up, and the fan turns off after a few seconds.

There are several possibilities for general compressor shutdown:1If the voltage does not reach the standard voltage of the air conditioner, the compressor will not be able to drive due to the voltage.

2 The temperature of the air conditioner is adjusted too high, causing the temperature sensor of the air conditioner to sense a low temperature and shut down3 The circuit control board of the air conditioner is broken. 4 The starting capacitance of the compressor of the air conditioner is bad 5 There is a problem with the compressor.

The running light goes out in a few seconds, the external machine stops, and the voltage and current are normal.

Dial the plug and start anew, the fault is old.

In this case, it means that the air conditioning control panel or temperature sensor is faulty, and it is recommended that you contact the relevant after-sales customer service for professional repair.
