What is the problem that the air conditioner always jumps automatically?

There are many reasons for this, but the possible cause is the phenomenon of the compressor protection device 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 exclusions of high pressure, high pressure, and overheating: 1. Refrigerant.

Plethora. Reduce the refrigeration dose appropriately. 2. Poor heat dissipation. Check the condenser pipe for dirt and dirt and clean the condenser.

3. The pipeline system is blocked. Refer to the pressure gauge.

Judgment, exclusion, and re-systematic processing. 4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned.

5. 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 electrical problem is:

1. Control circuit board failure. 2. The temperature sensor is overloaded and the information is wrong. 3. The power supply wiring is loose and the contact is poor.

4. The starting capacitor or compressor starting coil is burned out. There are many reasons, and it is recommended to find a professional maintenance personnel to check it.

The air switch is a little smaller, or the air conditioner has an instantaneous overload impact switch.

The air conditioner always jumps automatically, which should be due to a problem with the heat dissipation function of the external fan, which causes the temperature of the radiator to be too high during the air conditioner's operation for a period of time, resulting in protection.

Carefully inspect the air conditioner's dedicated wiring and the socket for poor contact.

Causes and solutions for the automatic switching of the air conditioner without stopping:

1. Whether there are reflective objects on the opposite side of the indoor unit of the air conditioner, such as mirrors or TVs.

2. Whether the remote control is in good condition, (whether the keys are sticky, clean) and other remote controls should not be placed with the indoor unit of the air conditioner.

If so, it is the manual switch of the air conditioner that hits the automatic and adjusts to the operation.

It is the heat dissipation network of the external unit that is dirty and cannot dissipate heat well, resulting in the self-protection of the compressor and the shutdown. It is a problem with the fan motor or capacitor of the external unit, check the fan and heat dissipation network of the external unit. It may be that the voltage is unstable or the temperature sensor is deteriorating, check the voltage or the sensor.

1. The temperature controller of the indoor unit is damaged

When the temperature controller of the indoor unit of the air conditioner is damaged, the various modes of the air conditioner will not be able to be used normally, resulting in the phenomenon of mode failure and automatic mode jumping. In this case, unload the shell panel of the indoor unit, and remove the 3-4 cm copper sleeve on the copper pipe plate, and replace the tube temperature sensor head with a new one.

2. Heat dissipation failure of outdoor unit:

If the heat dissipation of the outdoor unit of the air conditioner is abnormal, it will cause the operation of the entire air conditioner to be abnormal, and various modes cannot be used normally, and the phenomenon of mode jump will occur. In view of this situation, it is recommended to turn off the air conditioner in time and contact the after-sales maintenance personnel for maintenance.

3. Damage to the outdoor capacitor

If the starting capacitor of the indoor unit is damaged, the fan will stop rotating, resulting in a chaotic air conditioner mode conversion due to the high temperature. In this case, it is recommended to contact the after-sales maintenance personnel directly to replace the starting capacitor of the air conditioning fan.

4. The key of the remote control is faulty

If the buttons of the remote control of the air conditioner are sticky or malfunctioning, it will also cause the air conditioner to have the problem of mode jumping. It is recommended to check the keys of the remote control in time to see if there is any adhesion or other buttons that are concave and cannot pop out.

It is likely that the voltage of the air conditioner is unstable, or the power supply of the air conditioner is faulty, or the motherboard of the remote control may be short-circuited.

First of all, if the air conditioner is automatically turned on and off frequently, check whether it is set to turn on and off at a regular time. If it is set, it is normal for the air conditioner to automatically turn on, so it will not have much impact.

Secondly, there may be electromagnetic interference in the frequent automatic switching of the air conditioner, check whether there are household appliances near the air conditioner, and whether there is electromagnetic interference! In this case, you need to turn off the electrical appliances near the air conditioner, and then whether the air conditioner will still turn on automatically. This situation also has a relatively large impact on the air conditioner.

Finally, see if there is a problem with the air conditioner circuit board. Check whether the circuit board of the air conditioner is wet; Inspect the parts on the air conditioner's circuit board for damage. If it is really damaged, it will affect the comparison, and it is estimated that it will be repaired.

1. Causes and solutions for the air conditioner to trip after a few minutes of turning on:

1. To ensure that the voltage is normal, replace it with a new leakage switch, if it is not successful, it is the place where the air conditioner has a short circuit, and it should be carefully checked.

2. First check whether the leakage protector is normal, and then check whether the air conditioner is leaking.

3. The four-way valve blows air, causing a short circuit in high and low voltage, and the current rises sharply, and it will also trip.

4. The condenser fin of the air conditioner is too dirty, resulting in high heat load, clean it.

5. During the peak hours of electricity consumption, the general voltage is low, and the current of the air conditioner press is large, so add an AC voltage regulator with high power and higher power.

2. Check whether the starting capacitor of the compressor is invalid.

1. When using air conditioners in daily life, if they are not used properly, they will not only be uncomfortable, but also cause air conditioning diseases. So when using an air conditioner, you should pay attention to the following:

2. Inverter air conditioners have many functions and outstanding performance, but they do not mean omnipotent, and inverter products are relatively more functional or intelligent functions. However, when using it on a daily basis, it is also necessary to operate it according to the daily usage habits of the air conditioner.

3. When purchasing air conditioners, they must be purchased according to the actual area to avoid overloading the air conditioner to run, which not only has a bad temperature control effect, but also consumes more electricity when the air conditioner is running.

4. The outdoor unit of the inverter air conditioner has a microcomputer control board to air the operation of the inverter compressor, so the circuit board is easy to be damaged in a high temperature and humid environment, so the outdoor unit should be installed in a dry and ventilated place to avoid sun exposure and rain as much as possible.

5. Avoid switching the air conditioner back and forth when the inverter air conditioner is used, because the inverter air conditioner will intelligently adjust the operation of the compressor after it is turned on, and when the room temperature reaches the set temperature, the air conditioner will run at low frequency and save energy.

6. When the room temperature changes, the air conditioner will refrigerate and heat according to its own temperature control induction, if the user turns on and off the air conditioner too frequently in use, then the use of inverter products is undoubtedly no different from the fixed frequency air conditioner.

Check whether the external unit is leaking or short circuit, generally the internal unit has normal air output, and check the external machine circuit when the external unit triggers the start tripping.

The fuse in the special circuit of the air conditioner is blown out, or the power switch is in poor contact, or the power supply is out of phase. At present, many families only use one power supply, which will cause abnormal power supply due to the abnormal operation of other electrical appliances.

The power supply used by the air conditioner is too low, and when the voltage is less than 10% of the single-phase normal voltage of 220V, that is, 198V or below, the refrigeration compressor in the air conditioner is difficult to start.

If the knob on the temperature controller is not dialed to the appropriate position, if it is dialed to a higher position, when the power is connected, the temperature in the air conditioning room has not reached the upper limit of the set temperature, and the compressor cannot start running.

High pressure relay action, such as the condensing pressure is too high, so that the high pressure relay acts, stopping the operation of the compressor.

Low-pressure relay action, such as insufficient refrigerant in the refrigeration system, resulting in the compressor suction pressure is too low, so that the low-pressure relay action stops the operation of the compressor.

When the current of the compressor and fan motor is too large, the power supply will be cut off by the overload protection relay.

Air conditioner trip solution.

Check the cause of the fuse blowing inside and outside the air conditioner, and take measures to prevent it from blowing again, which should be adjusted and repaired in time. It is recommended that households with air conditioners should set up a special power supply to basically prevent the air conditioner from tripping.

If the local power supply voltage is often in a low state, it should be used with reliable power supply regulation, and at the same time, it is recommended that families with more household appliances use a special power supply.

Adjust the knob on the temperature controller to the desired position, that is, adjust it according to the temperature required by the air-conditioned room.

Check the cause of the high condensation pressure and rule it out so that the condensation pressure returns to normal pressure.

Check the cause of insufficient refrigerant in the refrigeration system and rule it out so that the suction pressure is restored to normal pressure.

Check the cause of overload of the compressor motor and fan motor and rule it out. In the case of heat production, the heat pump-assisted electric air conditioner uses both electric heating and heat pump-assisted heating. The heating efficiency is high, and the power consumption is between the heat pump type and the electric heating type.

The disadvantage of heat pump hot and cold air conditioner is that the machine failure caused by the failure of the four-way solenoid directional valve used is that the four-way electromagnetic directional valve of famous brand products has good working reliability.

If the air conditioner is turned on and does not train the limbs to jump out of a minute, if it is said that the air conditioner will automatically jump off in less than a minute after the air conditioner is turned on, then there may be compressor damage, compressor damage or short circuit, but the case of short circuit is relatively large, because of the place of the compressor.

The temperature of the air conditioner compressor is too high, causing the system to automatically protect. Check to see if the radiator is too dirty or the fan won't spin.

The air conditioner jumped from Zheng Chazhi in less than a minute after it was turned on, it is likely that there is a problem with the air conditioner, or there is a problem with the air conditioning line, and the voltage has no way to drive the air conditioner. Celebrants.

When the air conditioner is turned on, it takes less than a minute. First of all, know the operation of the air conditioner, if the automatic jump then I don't know what kind of jump it is, you can continue to ask me, what kind of jump you are, it may be that the air conditioner automatically shuts down and jumps to the past, and then does not run, does not refrigerate, it may be that the air conditioner will start a forced shutdown in less than a minute, and then the suspicion can still be displayed, if these are not. Then it may be that the air conditioner is running alone, if these are not, then it may be the tripping phenomenon caused by the leakage of the spine grounding wire when the air conditioner is running alone, and it may be that you have those leakage protectors connected to the total distribution box, many of them are if the leakage is serious, he will trip, right?

The automatic tripping of the air conditioner may be due to the lack of square wires, or the power strip of the air conditioner is burned.

The problem of setting, many inverter air conditioners will jump automatically, you can set it up according to the manual.
