What is the reason why the air conditioner compressor trips as soon as it starts

It may be due to a blown fuse in the special circuit of the air conditioner, or a poor contact of the power switch, or an out-of-phase power supply. It's all because there is only one power supply at home, which leads to abnormal power supply. Therefore, first of all, check whether the fuse of the air conditioning circuit has blown out due to long-term use, and replace it.

It may be that the power supply used in the air conditioner is too low, and the refrigeration compressor in the air conditioner is difficult to start. At this time, only one transformer needs to be installed for stable maintenance. It may be because the dial button on the thermostat is not in the right position, but is set to a higher position, and then the power is turned on.

If the temperature in the air-conditioned room does not reach the upper limit of the set temperature, the compressor will not start. Dial the button to the appropriate position and start the machine. It may be because of the action of the high-voltage relay, such as the high condensation pressure, which causes the high-voltage relay to act, and the compressor stops running, and it is necessary to ask professional maintenance personnel to come to check and repair.

It may also be that the low-pressure relay is acting, and the refrigerant in the refrigeration system is insufficient, resulting in the compressor suction pressure being too low, resulting in the low-pressure relay action and stopping the compressor operation. Please solve it after sale; There is also a possibility that when the current of the compressor and fan motor is too large, the overload protection relay acts to cut off the power supply, turn off the air conditioner in time, and use it reasonably to solve the problem.

The compressor trips as soon as it starts, and the internal unit runs normally when tested separately, then the fault can be judged to be in the outdoor unit. First of all, open the machine shell to check the resistance of the power line L and N to see if it is , if there is no short circuit in the two wires, and then see if there is a short circuit to the ground. After eliminating them one by one, check the starting capacitor of the compressor to see if the capacitor is broken down and short-circuited (the capacitor of the air conditioner is also a component that is often broken in the use of the air conditioner).

Reasons and maintenance methods for the air conditioner compressor to trip as soon as it starts:

1. The instantaneous starting current of the air-conditioning compressor is too large, causing the Midea air-conditioning compressor to trip as soon as it starts; Replace the high-power protection device.

2. Detect whether the capacitor of the air conditioning compressor has a breakdown short circuit; Timely repair or replacement.

3. It can detect whether there is a short circuit or a short circuit to the ground on the two wires.

4. Overheating and short circuit of the air conditioning compressor: it can detect whether the radiator of the outdoor unit of the Midea air conditioner is too dusty and whether the heat dissipation effect is good; Clean the radiators of Midea's air conditioners regularly.

5. Air conditioning compressor leakage; Detect whether the insulation layer of the compressor connection line is corroded in time and whether the compressor itself leaks; Check for exclusions.

6. Short circuit between the coils of the air conditioning compressor; Check for exclusions.

Generally, the problem of tripping the air conditioner when it is turned on is:

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 your 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, which I have encountered. And capacitors. This is also the case with leakage protectors.

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.

7. None of the above reasons are the above, the air conditioner trips as soon as it is turned on, and the compressor is broken.

When the air conditioner trips as soon as it is turned on, it means that it is caused by excessive current caused by the internal fault of the air conditioner, and the following are three reasons that may cause the air conditioner to trip when it is turned on, I hope it will help you. 1. If it trips in a few seconds as soon as the machine is turned on, it may be that the varistor on the circuit board is broken, the voltage is unstable and the varistor is bad, or the circuit board is short-circuited or the cross-current fan motor is faulty; 2. If you turn on other functions such as air supply and do not trip, it means that there is a problem with the fan or compressor of the outdoor unit; 3. Consider the air switch, because the carrying current will not reach the nominal value after the air switch is effective, please do not deal with it yourself, it is best to find a professional air conditioner maintenance personnel to deal with it.

Air conditioning compressor.

The reasons for tripping as soon as it starts are:

1. The fuse in the special circuit of the air conditioner.

It is burned out, or the contact of the power switch is poor, 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.

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

3. The knob on the temperature controller is not dialed to the appropriate speedy position, such as dialing to a higher position, when connected to the power supply, the temperature in the air-conditioned room has not reached the upper limit of the set temperature, and the compressor cannot start running.

4. The action of the high-pressure relay, such as the condensation pressure is too high, makes the high-pressure relay act and stops the operation of the fluttering compressor.

5. Low-pressure relay action, such as refrigerant in refrigeration system.

Insufficient, resulting in the compressor suction pressure is too low, so that the low-pressure relay acts, stopping the operation of the compressor.

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

1. The instantaneous starting current of the air-conditioning compressor is too large, which makes the overload protection relay act and cut off the power supply, resulting in the air-conditioning compressor tripping as soon as it starts.

Maintenance method: The high-power protection device needs to be replaced. Check the cause of overload of the compressor motor and fan motor and rule it out.

2. The button on the temperature controller is not dialed to the appropriate position, such as dialing to a higher position, when the power supply is connected, the temperature in the air-conditioned room has not reached the upper limit of the set temperature (the temperature at the starting point), and the compressor cannot start running.

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

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

Maintenance method: Check the cause of insufficient refrigerant in the refrigeration system, and eliminate it to restore the suction pressure to normal pressure.

4. High pressure relay action, such as the condensation pressure is too high, so that the high pressure relay action and stop the operation of the compressor.

Maintenance method: Check the cause of the high condensation pressure, and eliminate it, so that the condensation pressure can be restored to normal pressure.

5. The air conditioning compressor is overheated and short-circuited.

Maintenance method: detect whether the capacitor of the air conditioning compressor has a breakdown short circuit, and repair or replace it in time. The short circuit between the coils of the air conditioner compressor can detect whether there is a short circuit or short circuit to the ground between the two wires, and can detect whether the radiator of the outdoor unit of the air conditioner is too dusty, whether the heat dissipation effect is good, and clean the air conditioner radiator regularly.

For example, there will be a short circuit between the internal coils of the compressor or a line collision, as well as internal mechanical failures (parts are stuck, lack of lubrication, and excessive wear of parts can cause excessive current tripping).

There are several scenarios in which a compressor failure causes tripping:

1. The instantaneous starting current of the air-conditioning compressor is too large, which will cause the air-conditioning compressor to trip when it starts, and the high-power protection device needs to be replaced.

2. The capacitor of the air conditioner compressor is broken down and short-circuited, which will cause the circuit breaker to trip and need to be repaired or replaced in time.

3. The phenomenon of short circuit or short circuit to ground in the wiring of the air conditioner compressor will cause the circuit breaker to trip and need to be rewired.

4. A short circuit between the coils of the air conditioner compressor will cause tripping, and the coil needs to be repaired or replaced.

A broken air conditioner compressor may cause tripping, but it is not necessarily a trip of the first liquid.

The air conditioning compressor is one of the most important components in the air conditioner, which is responsible for compressing the refrigerant into high temperature and high pressure gas and transmitting it to the evaporator to release the cold air. If the compressor is damaged or malfunctioning, it may not function properly, causing problems such as loss of cooling capacity or abnormal noise in the air conditioning system.

The air conditioner compressor may trip if it is broken. The air conditioning compressor is one of the core components of the air conditioner, which is responsible for compressing the refrigerant and lifting the refrigerant flow. The air conditioner compressor needs to consume a high amount of power when it works, so in the case of an overload or failure of the air conditioner compressor, it will lead to excessive current, which in turn will lead to trip protection.

In the case of overload or failure of the air conditioning compressor, the air conditioner will work abnormally, which may be manifested as poor refrigeration effect, failure of air conditioning function, refrigerant leakage and other phenomena. If it is not repaired or replaced in time, the overload or failure of the air conditioning compressor will also cause further damage to other components, which will increase the difficulty and cost of maintenance.

Therefore, if the above situation occurs, it is recommended to contact the air conditioning maintenance personnel in time for maintenance and inspection to ensure the normal operation of the air conditioning equipment.

Yes, when an aircon compressor is broken or malfunctioning, it can cause the circuit to overload and cause tripping. The compressor is a key component in the air conditioning system and is responsible for compressing the refrigerant to produce cold air. If the compressor is damaged or malfunctions, it may cause an abnormal increase in current, exceeding the load capacity of the circuit, thus triggering a trip protection mechanism.

A broken air conditioner compressor will not directly cause tripping, but if the compressor failure causes the current to be too high, the liquid blob may cause the fuse or protector to trip. In addition, if the air conditioner compressor fails due to abnormal system pressure, the pressure protector may be tripped if the pressure shield fails. Therefore, if the air conditioner fails, it is recommended to contact professional technicians for overhaul and repair in time.

A broken air conditioner compressor may cause a short circuit or overcurrent in the air conditioner, which can lead to tripping. However, it is not necessarily tripped, and the specific problem needs to be further checked and confirmed.

When an air conditioner compressor encounters a fault, such as a short or open circuit due to valves, capacitors, coils, etc., it consumes more power to operate properly and causes the circuit to be overloaded. This may trigger a fuse, leakage protector or circuit breaker, causing a tripping phenomenon. However, in some cases, due to the protective measures that exist in the design of the air conditioner itself, even if there is some kind of fault inside the compressor, the power supply** will not be interrupted and the potato will not be tripped.

In addition, there are other reasons that may lead to the phenomenon of tripping and annihilation, such as excessive temperature difference between indoor and outdoor, unstable power supply voltage, etc. Therefore, if you suspect that the compressor of the air conditioner is faulty, causing the tripping phenomenon, it is recommended to seek professional repair services to avoid safety accidents or damage to Huaihong equipment.

It may be that the air conditioner compressor cannot carry the instantaneous current that passes through the air conditioner when it starts. First of all, check whether the power protection switch of the air conditioner is not enough, if this is the case, you need to replace a more powerful air protection switch to solve this phenomenon. Other cases:

1. Check whether the power supply in the special power socket for air conditioners is out of phase. If so, just reconnect the line according to the standards and requirements. 2. When using the air conditioner, the voltage of the power grid is too low, resulting in the situation that the computer detects that the voltage is too low when the air conditioner starts, resulting in the air conditioner compressor triggering the overvoltage protection mechanism, and it will trip directly and cannot start the air conditioner normally.

In this case, it is necessary to wait for the voltage to stabilize before using the air conditioner. 3. If the high and low pressure relay of the air conditioner acts, if the condensing pressure is too high or the suction pressure of the compressor is too low, this situation will occur, which will cut off the power supply and stop the operation of the compressor. At this time, it is necessary to check the internal wiring or components of the air conditioner to see if the specific damage is made, and repair and change it accordingly.
