Why does the air conditioner stop after a few minutes of starting, and then it doesn t start

This phenomenon can be divided into two situations, one is normal downtime and the other is abnormal downtime.

1. Normal shutdown.

When the air conditioner reaches the set temperature, it will shut down, and then start when the room temperature rises, and then stop when it reaches the set temperature.

2. Abnormal shutdown generally refers to the existence of problems with the air conditioner, and the basic problems are as follows:

1. Lack of fluorine or too much fluorine, lack of refrigerant in air conditioning will lead to compressor thermal protection.

2. The power supply voltage is insufficient, and the mains power supply is unstable.

3. The starting capacitor of the compressor is bad, and the sensing probe of the internal machine is bad.

4. The radiator of the external unit is dirty or has poor heat dissipation.

Practical common sense in the use of air conditioners.

1. Pay attention to line safety: it should have a suitable power capacity and a reliable dedicated line connection, and have a reliable grounding wire.

2. Pay attention to carefully adjust the room temperature: the room temperature is set high during refrigeration1, and the room temperature is set low during heating2, which can save more than 10%, and the human body can hardly perceive the difference in temperature.

3. Clean the filter regularly: dust will clog the filter mesh and reduce the effect of cooling and heating, so it should be cleaned once every half a month. Minimize the number of doors and windows, and use thick, light-transmitting curtains to reduce heat exchange between inside and outside the room, which is conducive to saving electricity.

4. Do not block the air outlet of the outdoor unit: otherwise it will also reduce the effect of cooling and heating and waste electricity.

5. Choose the appropriate air outlet angle: the cold airflow is heavier than the air and is easy to sink, while the warm airflow is the opposite. Therefore, the air outlet is upward during refrigeration and downward during heating, and the temperature regulation efficiency is greatly improved.

6. Control the state setting during start-up and use: when start-up, set high cold and high heat to achieve the control purpose as soon as possible; When the temperature is suitable, change the medium and low wind to reduce energy consumption and noise.

Why does the air conditioner stop after a few minutes of starting, and then it doesn't start Suggestion:

1. Check whether the temperature sensing head of the outdoor unit is short-circuited or open-circuited, if it is short-circuited or open-circuited, please replace it.

2. Check whether the indoor temperature sensor head is short-circuited or open-circuited, if it is open-circuited or short-circuited, please replace it.

3. Check whether the outdoor compressor lacks refrigerant, if it is a lack of refrigerant, the compressor will heat up after operation, resulting in self-protection of the compressor.

4. Check whether the external cooling fan is rotating, if it does not rotate or is very slow, please change the starting capacitor of the fan, if it does not rotate, the fan is broken.

I hope the above 4 points can solve the problem for you.

Summary. Dear Hello <>

There are many reasons why an air conditioner can shut down less than a minute after it is turned on. Here are some of the reasons that cause downtime after your aircon is turned on:1

Power supply problems of the air conditioner: The power supply is unstable, and overpower or underpower will cause the air conditioner to shut down after it is started. 2.

Failure of the outdoor unit of the air conditioner: The failure of the outdoor unit of the air conditioner will also cause the air conditioner to shut down after it is started. It's a fan motor problem, a faulty compressor, etc.

3.Fluorine leakage from the connecting pipes of the internal and external units: Fluorine leakage from the connecting pipelines will cause the compressor to operate abnormally, which will lead to the shutdown of the machine after starting.

4.Internal Faults: Faults inside the air conditioner, such as damaged circuit boards, problems with sensors, etc., can also cause the machine to shut down after starting.

5.Poor cleaning: Cleaning problems such as dust, foreign body intrusion, and clogged filters can also cause automatic shutdown protection after the air conditioner is started.

The air conditioner started and stopped in less than a minute.

Dear Hello <>

There are many reasons why an air conditioner can shut down less than a minute after it is turned on. Here are some of the reasons that cause downtime after your aircon is turned on:1

Power supply problems of the air conditioner: The power supply is unstable, and the overpower or underpower will cause the air conditioner to shut down after starting. 2.

Failure of the outdoor unit of the air conditioner: The failure of the outdoor unit of the air conditioner will also cause the air conditioner to shut down after it is started. It is the problem of the source limb of the fan motor, the failure of the compression rock weighing machine, etc.

3.Fluorine leakage from the connecting pipes of the internal and external units: Fluorine leakage from the connecting pipelines will cause the compressor to operate abnormally, which will lead to the shutdown of the machine after starting.

4.Internal Faults: Faults inside the air conditioner, such as damaged circuit boards, problems with sensors, etc., can also cause the machine to shut down after starting.

5.Poor cleaning: Cleaning problems such as dust, foreign body intrusion, and clogged filters can also cause automatic shutdown protection after the air conditioner is started.

You can check if there is a problem with the above aspects first.

1. I accidentally touched the button of the air conditioner.

Remote control for air conditioning.

There are a lot of buttons on it, so let's first check whether the timer switch option on the remote control of the air conditioner is on, and if so, turn it to off. Or see if the remote control is in sleep mode, it will automatically shut down when the temperature reaches the adjusted temperature, and you can convert this mode to normal mode.

2. There is a problem with the temperature controller.

It may be that the temperature controller of the indoor unit is damaged. Open the shell of the indoor unit, there is a 3 4 cm long copper sleeve on the copper pipe coil inside, and the tube temperature sensor head is stuck inside.

3. There is a voltage problem.

Air conditioners are equipped with automatic over- and under-voltage protection functions, so when the grid voltage is unstable beyond the allowable range, it will automatically shut down. If the grid is constantly like this, air conditioning cannot be used. You can only find the power supply department to solve it.

4. Electromagnetic interference.

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.

The problems of the air conditioner stopping after starting it may be: the air conditioning system is faulty, overload protection is triggered, the voltage is unstable, the outdoor unit of the air conditioner is blocked, and the air conditioner filter is blocked.

1. The air-conditioning system is faulty.

The most common reason why the air conditioner stops after it starts is that the air conditioning system is malfunctioning. It could be due to damaged sensors inside the air conditioner, malfunctioning compressors, burned out circuit boards, etc. At this time, it is recommended to contact professional air conditioning maintenance personnel for maintenance and maintenance in time.

2. Overload protection triggering.

The air conditioner stops shortly after it is started, and it may also be caused by an overload protection trigger. When the air conditioner runs for too long or the load is too large, the overload protection mechanism will be activated, so that the air conditioner will automatically stop running. At this point, you just need to wait for a while for the air conditioner to cool down and then you can restart.

3. The voltage is unstable.

If the voltage in your home is unstable, it is also possible that the air conditioner will stop shortly after it is turned on. If the voltage is unstable, the internal circuit board of the air conditioner will burn out, so that the air conditioner cannot operate normally. In this case, it is recommended to use a voltage regulator to stabilize the voltage, or contact the power company for inspection and repair.

4. The outdoor unit of the air conditioner is blocked.

The blockage of the outdoor unit of the air conditioner is also one of the reasons why the air conditioner stops shortly after it is turned on. If the outdoor unit is clogged and the air cannot circulate, the internal pressure of the air conditioner will be too high, so that the air conditioner will automatically stop running. At this time, you only need to clean up the debris on the outdoor unit and let the air flow be balanced.

5. The air conditioner filter is blocked.

Clogged air conditioner filters are also one of the reasons why the air conditioner stops shortly after it is turned on. If the air conditioner filter is clogged and the air cannot circulate smoothly, the pressure inside the air conditioner will be too high, which will cause the air conditioner to stop running automatically. At this point, you only need to clean the air conditioner filter.

Bad pressure protection or compressor starting capacitance.

Why does the air conditioner stop after a few minutes of starting, and then it doesn't start

Hello dear, I will answer for you this time, please be patient. Cong does <><

1.The power supply voltage is unstable, or the compressor thermal protection shutdown is caused by the poor temperature exchange of the air conditioner. 2.

For example, the filter screen of the indoor unit is too dirty, the fan speed is too slow, the lead-shaped aluminum foil heat sink of the outdoor unit fin is too dirty, the fan speed is too slow, or the blades are broken and deformed. In addition, this situation will also occur when the outdoor unit is exposed to the sun for a long time, which affects ventilation and heat dissipation.
