Haier air conditioner stopped directly after turning on, why did Haier air conditioner stop after a

1. In most cases, the air conditioning system stops working intermittently due to poor heat dissipation. Clean and inspect the heat sink.

2. There may be a problem with the temperature sensor, there is a temperature sensor inside the air conditioner evaporation box, when the sensor detects that the temperature of the evaporation box is too low, the work of the air conditioning compressor is terminated, so check whether the temperature is damaged.

3. Commonly known as ice blockage, that is, there is water in the air conditioning system, and the water freezes and blocks the pipeline after a while for air conditioning refrigeration, at this time it is not refrigerated, and when it stops for a while, the temperature rises, and the ice melts and starts to refrigerate, so it is refrigerated, so intermittent refrigeration. At this time, it is time to change the air conditioner dryer.

Common causes and maintenance methods for automatic shutdown of air conditioners:

1. Check whether the timer switch option on the remote control of the air conditioner is on;

2. Or see if the remote control is in sleep mode, the air conditioner will automatically shut down when the temperature reaches the adjusted temperature, and convert this mode to normal mode;

3. If the air conditioner is used over age, there will be a lot of failures;

4. Check whether the air conditioning circuit board is damp;

5. Detect whether the parts on the circuit board of the air conditioner are damaged;

6. Check whether the heat dissipation network of the external machine is dirty and cannot dissipate heat well, resulting in the compressor self-protection skipping shutdown;

7. Check the system for low pressure protection for fluorine deficiency or overheating of the compressor temperature.

When using the air conditioner, it is unlikely that the air conditioner will automatically turn on and off, and the reason for the failure of the air conditioner is because the air conditioner circuit board is damaged or the air conditioner is automatically turned on or off when it is aging.

Summary. The Haier air conditioner is turned on and stopped, which may be because the indoor temperature reaches the set temperature and the automatic mode is turned on, it may be the compressor overcurrent protection, or the indoor fan may be faulty.

The Haier air conditioner is turned on and stopped, which may be because the indoor temperature reaches the set temperature and the automatic mode is turned on, it may be the compressor overcurrent protection, or the indoor fan may be faulty.

1. The automatic mode may be turned on, when the set temperature is close to the room temperature, it will stop when the set temperature is reached. It creates the illusion of failure when it is turned on and stops, but there is no problem with the actual air conditioner. 2. The voltage is abnormal and unstable.

Compressor overcurrent protection. It is recommended to try a different voltage stabilizing device. 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.

5. Damage to the thermostat: The thermostat of the indoor unit of the air conditioner is damaged, resulting in the inability to detect the indoor temperature, open the shell of the indoor unit, and there is a 3-4 cm copper sleeve on the copper pipe coil, which is stuck in the tube temperature sensing head. Replace the damaged thermostat.

6. Electromagnetic interference: check whether there are high-power electrical appliances near the indoor unit of the air conditioner, whether there is electromagnetic interference, in this case, you need to turn off the electrical appliances near the air conditioner, or move the high-power electrical appliances to the position, and then observe whether the air conditioner will automatically shut down.

Haier air conditioners always shut down automatically for the following three reasons: insufficient power supply voltage of the air conditioner, failure of the main control board of the air conditioner, and problems with the capacitance of the external machine.

1. Caused by the power supply voltage of the air conditioner: It may be caused by the overall voltage of the room during a peak period of use, or the voltage itself is unstable, which causes some household appliances to trip and cause this phenomenon. Therefore, it is recommended to stagger the peak period of electricity consumption, or wait until the peak period of electricity consumption has passed, and then check whether the air conditioner can be used normally.

2. The main control board of the air conditioner is faulty: this fault is generally that the air conditioner has been used for a period of time, and the air conditioner is often used in an environment where the voltage is unstable, and the voltage will cause the circuit board to age or even be damaged. Therefore, it is recommended to find Haier maintenance personnel to repair the main control board of Haier's internal machine.

3. There is a problem with the capacitance of the air conditioner outside: the air conditioner is overheated and enters the protection state, which requires a comfortable environment for the air conditioner. If the air conditioner is too dirty or exposed to sunlight, it is recommended to clean and maintain the air conditioner regularly to ensure your health and the normal use of the air conditioner.

Hello dear, there may be the following reasons for the automatic shutdown of Haier air conditioner: 1. When the remote control is in sleep mode, it will automatically shut down when the temperature reaches the adjusted temperature. So first set the remote control to normal mode; Or the timer switch option is on, or if so, turn it off.

2. The emergency switch of the air conditioner is not reset. It may be that there is a problem with the emergency switch (manual switch) of the air conditioner, and you need to unplug the power supply and pick back and forth. 3. Caused by poor contact between the bolt of the air conditioning line and the socket.

You can try to unplug the air conditioner switch and plug it into another latch to see if there will be an automatic shutdown. 4. The automatic shutdown of the air conditioner may also be caused by the grid voltage. Air conditioners are equipped with automatic over- and under-voltage protection functions, so when the grid voltage is unstable beyond the allowable range, it will automatically shut down.

If the grid is constantly like this, air conditioning cannot be used. In addition, the voltage regulator itself also has its own adaptation range, and when the power grid fluctuates too much, it cannot be adjusted, resulting in the automatic shutdown of the air conditioner. 5. It may be that the temperature controller of the indoor unit is damaged.

Open the shell of the indoor unit, there is a 3 4 cm long copper sleeve on the copper pipe coil inside, and the tube temperature sensing head is stuck inside. 6. The outdoor unit is installed in the grille, or there is a block around it, and the ventilation is poor, resulting in protection shutdown. 7. The starting capacitor of the cooling fan of the outdoor unit is damaged, the fan does not rotate, and the temperature is too high and the protection stops.

It can be seen with the naked eye. When the fan does not rotate, replace the fan starting capacitor. 8. It may be the reason why most of the refrigeration economy leaks out, the refrigeration capacity of the air conditioner is greatly reduced, and the machine is easy to overheat.

The air conditioner that leaks from the refrigeration economy is obviously much louder than before, and it is easy to identify. Let the master who repairs the air conditioner add the refrigeration and check for leaks.

Summary. Qinqin is happy to answer for you: Haier air conditioner stopped after a while when it was started, for the following reasons:

1.Power problem: When the power supply of the air conditioner is unstable, the machine will shut down soon after starting.

Check that the power plug and cord are not damaged or loose. 2.Overload Protection:

The protection device inside the air conditioner will automatically cut off the power supply when the voltage is too high or too low, and the current is too high. When the air conditioner is turned on and running for a period of time, overload protection is triggered, causing the machine to shut down. You need to wait for a while and try again.

3.Outdoor unit failure: When the outdoor unit of the air conditioner fails, it will cause the entire air conditioning system to fail to operate normally.

Kiss is very happy to answer for you: Haier air conditioner stopped after a while, for the following reasons: 1

Outdoor unit failure: When the outdoor unit of the air conditioner fails, it will cause the entire Shanpin air conditioning system to fail to operate normally.

The expansion that you have been given to you is: Haier air conditioner Kai Sleepy He maintenance process, as follows: 1

Unplug the power supply between the plug and socket of the air conditioner to avoid the risk of electric shock and leakage when maintaining the air conditioner. 2.Remove the shell of the air conditioner, the cabinet and hanging air conditioners are opened at both ends of the air conditioner, pay attention, do not stare too hard, too big is easy to damage the shell of the air conditioner.

3.Wash the dirt and build-up in the drained part of the ruler carefully. The drainage part is prone to dirt deposits, so it must be thoroughly disinfected regularly to ensure smooth drainage and prevent fine reproduction.

Hello dear, I'm glad to answer for you. There may be several reasons why Haier's air conditioner stops after starting for a while:1

Clogged filter: The air conditioner filter is not cleaned, resulting in poor air circulation, which makes the machine work for a period of time and then stops for protection. 2.

Problems with the pipes or wires between the inside and outside of the unit: A faulty pipe or wire between the inside and outside of the air conditioner will cause the machine to be turned on for a period of time and then automatically protect the shutdown to avoid further damage to the equipment. 3.

Compressor failure: The internal failure of the air conditioner compressor will also cause the machine to stop automatically after a period of time. It is recommended that you first check whether the air conditioner filter is cleaned, and then check whether the pipes and wires are faulty if the filter is normal, if you do not find the problem, you need to contact a professional maintenance personnel to check whether the compressor is faulty.

The Haier air conditioner stopped after a while, which may be caused by the following reasons:

Cleaning problems: Dust or dirt accumulates inside the air conditioner, resulting in poor air circulation, which causes the air conditioner to overheat and shut down. It is advisable to clean the air conditioner filter and interior regularly.

Power supply problem: The power cord of the air conditioner is loose or the power socket is unstable, causing the air conditioner to shut down. It is recommended to check that the power cord and outlet are in good working order.

Fault problem: The air conditioner has a fault, such as circuit board failure, compressor failure, etc., resulting in the air conditioner shutdown. It is recommended to contact a professional maintenance personnel for inspection and repair.

Temperature setting problem: The temperature setting of the air conditioner is too low, causing the air conditioner to shut down automatically after reaching the set temperature. It is recommended to set the temperature within the appropriate range.

Environmental problems: The ambient temperature of the air conditioner is too high or too low, resulting in the overheating or overcooling of the air conditioner and the shutdown. It is recommended to use the air conditioner at a suitable ambient temperature.

If none of the above methods can solve the problem, it is recommended to contact a professional maintenance personnel for inspection and repair.

There are many reasons for downtime, but the possible cause is the phenomenon of the compressor protection device tripping. Compressor overload protection will trip to indicate that the high pressure of the system is too high or the overheating current is too high before the trace.

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, the evaporator or the strainer is fouled, and dust and scale.

Clean the evaporator or strainer.

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. Qinzhou shouted.

The electrical problem is:

Control board failure.

The temperature sensor is overloaded and the information is incorrect.

The power wiring is loose and the contact is poor. 4. The starting capacitor or compressor starting coil is burned out.

The information is insufficient, it can only be analyzed in this way, and there are many other possibilities, it is recommended to find a professional maintenance personnel to check it.
