What happens when the air conditioner trips as soon as it is turned on?

The reason why the air conditioner at home trips as soon as it is turned on: it may be a problem with the main engine of the air conditioner, as soon as it runs to refrigeration, it will be short-circuited inside, generating high-voltage current, resulting in tripping.

Prolonged use makes the air conditioner trip at high temperatures. Check whether the neutral wire and grounding wire are reversed or accidentally touched when replacing the compressor; Check again that the model of the compressor is the same as before.

Solution: Check the grounding wire and the neutral wire, and connect the ground wire with the neutral wire; Replace the capacitors of the compressor; Use a coarse-pointed, dedicated air-conditioning cable; Replace the leakage switch. 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.

The best thing to do is to let a professional maintenance person take care of it.

Before the air conditioner is turned on, we must do a comprehensive "diagnosis", check whether the air conditioning equipment has "faults", according to the results of the inventory, under the guidance of professional and technical personnel, do a good job of maintenance and cleaning, the maintenance and cleaning should be in place, including the shell, body, and filter of the outdoor unit and the indoor unit, and then start the trial operation to observe the refrigeration speed and effect.

After the air conditioner is turned on, the maintenance times during the air conditioner start-up process are determined by many factors such as environmental conditions, climatic conditions, number of hours of start-up, surrounding dust, air cleanliness, and whether the room is clean.

The environmental conditions are not good, the weather is hot, the air conditioner is outdated, the air conditioner is turned on for a long time, and the number of maintenance during the air conditioner start-up process increases, usually once every month and a half.

Analysis of the reasons why the air conditioner trips as soon as it is turned on:

1. The fuse in the special circuit of the air conditioner is blown out, or the contact of the power switch is poor, or the power supply is out of phase. At present, many users use a power supply in combination, and the power supply is abnormal 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 (220V), that is, 198V or below, it is difficult to start the refrigeration compressor in the air conditioner.

3. The knob on the temperature controller is not dialed to the appropriate 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 (the temperature at the starting point), and the compressor cannot start running.

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.

5. 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 and stop 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.

Check method for tripping when the air conditioner is turned 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. 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 we have encountered. There is also capacitor leakage, which will also occur in protectors.

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

5. During peak hours, the general voltage is low, the current of the air conditioning compressor is large, and an AC voltage regulator with high power is added. Of course, tripping may also be related to the irregular starting sequence of the air conditioner.

The air switch and the starting current of the machine are not matched.

If the switch is not enough, there is also a possibility of power tripping.

The machine is not grounded, or the air conditioning machine leaks, short circuits, etc.

The voltage is not enough, there may be too many electrical appliances in the circuit, so that the resistance is too large, and the current flowing is less, you can see if the plug of the air conditioner is on the same socket with other electrical appliances.

If the total power in the circuit is too large, you can replace the appropriate fuse, or turn off some other electrical equipment with higher power.

The reasons and solutions for frequent tripping of household electricity are as follows:

1.Because household appliances are heavily loaded, exceeding the rated load is an overload protection trip.

2.Because some electrical appliances have grounding phenomena, they trip due to leakage protection. You can gradually plug in or open the electrical appliances, when opening a certain electrical appliance tripping, you must first check whether there is a suspicion of leakage, or high-power electrical appliances, the load has accumulated to exceed the rated load.

3.Check whether there is leakage can turn off or unplug other electrical appliances, turn on this one separately, if it is turned on normally, it means that it does not leak, if it will also trip, it means that the problem is on this equipment.

4.If there is no leakage equipment, it is a load problem, you can first see how big your air opening is (also pay attention to the allowable load of the meter), and then convert the total power of the electrical appliances you turn on in use, (refrigerator and air conditioner to compressor start whether the power is calculated), if it is indeed overload, it is impossible to adjust and avoid the problem of meter expansion and air replacement should be considered.

5.Finally, if none of the above problems are the above, then change to a new empty open with the same capacity to see if it is caused by empty opening failure or allergies.

Precautions. If you don't understand, you can also ask the electrician of the community property company for help, or you can find a qualified electrician and other professionals in the society to solve it, which is safer.

The air conditioner trips as soon as it is turned on, and there are several reasons: excluding the air conditioner, 1. The quality of the air switch is too poor. 2. During the peak period of re-consumption, the power supply voltage is low, the starting current of the air conditioner is large, and it takes a long time to start, and the switch is tripped

What happens when the air conditioner trips after a while? The guy taught you a few tricks, and after reading it, you are also a master.

Tripping is a self-protection mechanism for household appliances, and always tripping means that your air conditioner is out of order. The reasons why the air conditioner trips as soon as it is turned on are as follows: there is a short circuit inside the air conditioner, and the electric switch jumps quickly after it is turned on to play a protective role.

The current of the air conditioner is greater than the rated current of the electric switch, so after turning on the air conditioner, the electric switch quickly trips and plays a protective role. When the power switch fails, resulting in the power switch not reaching the rated current of the power switch, the power switch will trip. Workaround:

Replace the power switch. If it still trips, it is an air conditioner failure. You need to contact the after-sales service of the air conditioner for repair.

No matter what electrical appliances are, if there is a trip, there are many reasons, but look at your trip caused by leakage, find a multimeter to measure the resistance to the ground should be greater than 0 5m ohms, if a few thousand ohms below to see if there is water in that place, measure whether the shell of the outer machine is charged, the insulation is not good or the cable has a touch of the casing, and the door-to-door fee for repairing the air conditioner is also 50. Let's find someone to repair it as soon as possible.

Poor contact. Some air conditioners are installed on the wall, while others are pressed on the ground, and if the air conditioner is installed on the wall, it will require a long wire. At this time, if the length of the wire is not enough, it will affect the fit between the plug and the socket.

If the plug and socket are not together, the air conditioner will always trip.

If it is an air conditioner placed on the ground, pay attention to whether there are children at home, if the child accidentally kicks the air conditioner wire while walking or running. At this time, the air conditioner will also trip suddenly, which will also affect the safety of the child.

Could the main cause be a problem with the current? There may be a cause of electricity leakage behind the air conditioner. Or the current passing through the air conditioner is greater than the air conditioner itself.

So when the air conditioner can't withstand the current. The air conditioner is more likely to trip. What happens when the air conditioner trips?

How can I prevent my air conditioner from tripping all the time? To ensure the size of the current. Also pay attention to the plug and socket, be sure to connect together.

Common reasons why an aircon trips::

1. If the air conditioner trips as soon as it is turned on: there is leakage in the line behind the air conditioner switch or a short circuit in the circuit board;

2. If it trips after turning on the machine for a while, it may be that the varistor on the circuit board is broken or the cross-current fan motor is faulty.
