What is the reason why the air conditioner jumps by itself, and the air conditioner automatically ju

If there is a problem with the temperature sensor or it is not set properly, the compressor overheating protection will cause the temperature to jump by itself.

1. Causes of compressor overheating.

1.It's that there is less freon, and the air conditioner can't cool it.

2.The continuous heat dissipation temperature of the outdoor unit is too high, and the heat dissipation of the heat dissipation part is not good, resulting in the excessive load of the outdoor unit of the air conditioner.

3.The supply voltage is too low. Check the voltage. The voltage is too low for the air conditioner to run.

4.The outdoor unit is too dirty. Observe whether the fins of the outdoor unit are too dirty, and clean them to observe the effect. The external unit is too dirty, which affects the heat dissipation of the air conditioner, resulting in overheating of the compressor and an increase in the working current.

Compressor and ancillary circuit faults, most of which are compressor capacitor faults. Rarely, it will be a compressor failure. (Because "the maximum time can be used for four hours") Second, the method of setting the temperature There are two temperatures displayed on the air conditioner, one is the indoor temperature; One is the outdoor temperature, and these two temperature transmission sensors are installed on the air inlet side of the internal and external units respectively.

Only one temperature is displayed on the display window, and you need to switch it yourself. Older air conditioners only have one temperature display, which is usually the room temperature. The temperature you set is only displayed when it is set, and it automatically switches to the room temperature when it is running.

So when you set it to 17 degrees, put down the remote control, and the indoor unit will display the indoor or outdoor temperature in a while. 3. Temperature sensor solutionThe sensor is generally installed on the return air outlet and heat sink.

You can check to see if the contact is not good, and if it doesn't work, send it for repair.

First, when the air conditioner is heating, your set temperature is higher than the indoor temperature, and the air conditioner starts to work. Coupled with factors such as heat loss and uneven air distribution, the indoor temperature is lower than the set temperature. That is what you said, the hot air is more than 20 degrees, and the indoor temperature is 20 degrees.

Second, when the air conditioner is refrigerated, the temperature is set at 30 degrees, if the indoor temperature is equal to or less than 30 degrees at this time, the air conditioner is not refrigerated, that is, the compressor does not go, but the indoor fan moves. If the indoor temperature is higher than 30 degrees, the air conditioner compressor will start to cool and maintain it at about 30 degrees. Therefore, as long as the air conditioner is in cooling mode, the indoor will definitely not be higher than 30 degrees, and there will be no hotter phenomenon.

Hope it helps!

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.

If the air conditioner is jumping on and off on its own, it could be one of the following reasons:

1.Faulty temperature sensor: The temperature sensor of the air conditioner may malfunction, causing the air conditioner to not read the room temperature correctly, resulting in the failure of the automatic power on and off function.

2.Power supply problems: There may be problems with the power supply line of the air conditioner, such as poor contact of the power line, loose power plug, etc., which causes the air conditioner to automatically turn on and off.

3.Control panel failure: The control panel of the air conditioner may malfunction, resulting in the air conditioner being unable to properly control the power on and off functions.

4.Remote control problem: There may be a problem with the remote control of the air conditioner, such as the remote control button is out of order, the remote control battery is low, etc., causing the air conditioner to automatically turn on and off.

Solve the Fangtan Bridge Method:

1.Check that the temperature sensor is working properly and replace it if there is a problem.

2.Check that the power lines are in good contact and that they need to be repaired or replaced if there are problems.

3.Check whether the control board is working properly, and replace it if there is a problem.

4.Check whether the remote control is working properly, if there is a problem, you need to replace the battery or replace the remote control.

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.

There can be several reasons why an air conditioner automatically trips:

1.Circuit failure: The air conditioning circuit is faulty, resulting in excessive current, and the protection circuit is automatically tripped.

2.Overload protection: During the use of air excitation leakage, if the load is too large, the current will exceed the rated current, and the protection circuit will be automatically tripped.

3.The temperature is too high: the air conditioner is used for too long and the temperature is too high, and the automatic trip protection circuit.

4.The power supply voltage is not stable or rotten: If the power supply voltage is unstable, it will cause the current of the air conditioner to fluctuate, and the protection circuit will be automatically tripped.

If the air conditioner frequently trips automatically, it is recommended to contact a professional maintenance personnel for inspection and repair.
