What s going on when the air conditioner is plugged in and trips right away?

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 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 position, such as dialing to a higher position, when the power supply is connected, the temperature in the air conditioning room has not reached the upper limit of the set temperature, and the compressor can not start running.

4. High-pressure relay action, such as the condensation pressure is too high, so that the high-pressure relay action stops 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.

If the air conditioner is plugged in and then the air conditioner trips when it is turned on, it must be a short circuit in the air conditioner and needs to be checked; If the air conditioner is plugged in and does not turn on, it will trip, which is another reason.

The air conditioner tripped when it was plugged in, and I thought it was a short circuit in the air conditioner, but it turned out to be this problem.

There is a short circuit in the air conditioner or the insurance capacity of your home is not enough.

The voltage is unstable. Can't afford it.

This needs to be checked from two aspects, one is the electrical circuit, and the other is the air conditioner itself. The reason from the circuit is generally because there is no difference in the color of the wire at the terminals of the socket board. If it is a problem with the air conditioner, it is generally a short circuit or leakage of the wires inside the power plug, or the electrical components in the air conditioner.

Check the reason why the air conditioner trips when plugged in:1. Check whether the neutral wire, ground wire, and live wire on the terminals of the air conditioner socket board are reversed.

Generally, the blue wire is the neutral wire, which is connected to the left side of the terminal of the socket board, and the yellow-green wire is the ground wire, which is connected above the terminal of the socket board. The circuit routing rule for the socket board is "fire ground". We can also use the on/off of the multimeter to determine the ground wire and neutral wire, correctly connect the terminals of the socket board, and complete the circuit wiring.

2.Troubleshoot the power cord of the air conditioner. Use a multimeter to detect whether the power cord is short-circuited, and then use a shake meter to shake the insulation resistance value of the power cord.

If it is greater than megaohm, there is no leakage. 3.Troubleshoot the internal electrical parts of the air conditioner.

If the above two steps have been checked and there is no problem, then there may be a problem with the inside of the air conditioner. You need to find a relevant professional or maintenance master to solve problems for us.

Turn on the air conditioner to trip, indicating that the current is too large, causing the leakage switch to automatically protect, it may be that the air conditioner has a short circuit, mainly measure the input line resistance of the air conditioner, to see if it is a direct short circuit, if it is normal, and then test the motor and compressor of the outdoor unit, you can also use the elimination method, that is, disconnect the outdoor unit or compressor and then open it to see if it trips, and look at the electric switch power supply part of the computer board There is also a possibility that your leakage switch has a problem, The current that it can withstand is lower than the current when the air conditioner is turned on.

The capacity of the electric shock protector is too low to cause the deformation of the tripping mechanism, and there is no fault at ordinary times, and when the air conditioner is turned on, it will trip over capacity. The main repair is to replace the electric shock protector with a larger capacity.

The power supply connection line of the internal and external units of the air conditioner mostly occurs in places where the power cord is lengthened, and it takes a long time and there are many mice.

Compressor and compressor capacitor, the capacitor is generally not easy to break, but after a long time, it may be possible, and the compressor is also very likely.

Self wiring, socket problems, less, but not impossible.

Check the power supply line of the air conditioner, the line is aging, and there may be a local short circuit. Simple test, disconnect the empty output, connect the temporary line directly with air conditioning, if you do not jump, you can confirm that there is a problem with the original line. If you jump, try another one, if you don't jump, it means that there is a problem with the one that jumps, if you jump both, change the empty test.

You can also use the shake meter to check the original old line.

Did you jump like this before?

The main reason is that 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.

It means that the air conditioner is broken and has to be repaired, and I am really looking forward to it.

If the leakage protection trips, it means that the internal circuit of the air conditioner has touched the shell.

If it is a short-circuit protection trip, it means that there is a short-circuit in the internal circuit of the air conditioner.

In either case, an experienced professional should be asked to inspect and repair it.

In both cases, the trip is caused, and the zero wire of the 16A socket is reversed with the ground wire. Or the air switch load current is low.

This may be a fault, a short circuit or a leakage, but in any case, you have to ask someone to repair and test.

If the line fails, it may be that the square number of the line is not large enough to trip the protection.

There may be a problem with the wiring of the air conditioner, and there may be a short circuit.

That is, the quota current of the empty opening is not large enough.

If it is a line or overload, you should find a professional electrician to repair it at home, and do not look for it yourself.

Say you have a problem with your air conditioner, so find someone to fix it.

The reason may be that the wattage of the power supply used by the air conditioner is too low, which is lower than the normal household voltage, so the compressor with the air conditioner cannot be moved, resulting in the whole air conditioner cannot start.

The reason may be that the current passed by the compressor and other destruction devices in the air-conditioning equipment is too huge in an instant, and the overload protection inside the air-conditioning takes effect, and the relay of the air-conditioner is started to protect the behavior, so the power supply is cut off, and the internal equipment of the air-conditioner should be protected in the process of use;

The reason may be that the line used by the air conditioner at home is aging, so the high-power electrical appliance of the air conditioner will trip as soon as Yu Feng starts it, and the solution is to update the line.
