Hisense Air Conditioner 1 5 HP Inverter Air Conditioner Turns On for 30 Seconds, What is the reason

Compressor starting capacitance, whether the capacity is appropriate, whether the wiring is loose, or fails.

3. The overload protector jumps off when the machine stops, or the terminal of the overload protector is loosened 4. The temperature is set improperly, and it starts in 3 minutes, and when cooling, the indoor is lower than the setting or the indoor is higher than the setting when heating.

5. The temperature measuring sensor (air inlet) is broken or damaged 60 The compressor itself is faulty, biting the cylinder (mechanical lock), etc.

Hello, in this case, the preliminary judgment should be that the refrigeration system has a corresponding failure, resulting in overload of the compressor.

The inverter air conditioner is turned on for 30 seconds, the compressor is stopped, and the normal operation is of course normal, and there needs to be a process when it starts.

Only the compressor does not rotate, the most likely cause is the phenomenon of the compressor protection device tripping.

Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high.

Causes and elimination of high pressure and overheating:

1. Too much refrigerant. Reduce the refrigeration dose appropriately.

2. Poor heat dissipation. Check the condenser pipe for dirt and dirt and clean the condenser.

3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned.

5. Fluoride deficiency is also possible. When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

The former is a hardware equipment problem, please professional maintenance personnel to come to the door to test, starting capacitors, signal board communication, compressor motors, etc. may fail.

If it's occasional, that's normal. In the following cases, the outdoor fan will work and the compressor will not work

1. When the air conditioner is just started. In order to protect itself, the compressor has some detection actions before starting, and in order to prevent the starting torque from being too large due to the unbalanced high and low pressure after the last shutdown, the compressor will not directly follow the fan to open, but has a lag.

2. The indoor temperature reaches the set value. Everyone's understanding of inverter air conditioning is often that the speed of the compressor can be continuously adjusted according to the indoor load, that is, the compressor will always be in a state of continuous inverter. But in reality, the speed of the compressor cannot be reduced to too low, otherwise it will cause poor oil return and overheating of the compressor.

Usually this lower limit is set at about 30% of the maximum speed. When the compressor speed is reduced to a minimum and the indoor temperature is still dropping, the compressor can only be shut down, while the outdoor fan will continue to operate.

Hisense fixed-frequency air conditioner stopped after more than 10 minutes of starting, what is the reason pro,Hello! The first reason may be that the chain hand is turned on the automatic mode, when the set temperature is close to the room temperature, the machine will stop when the set temperature is reached. It creates the illusion of failure when it is turned on and stops, but there is no problem with the actual air conditioner.

The second is that the voltage is abnormal and unstable. Compressor overcurrent protection. It is recommended to try a different voltage stabilizing device.

The third suspect in front of the shed is that the temperature of the indoor coil is too high, resulting in a protective shutdown. When the indoor temperature is 26 degrees Celsius and the outdoor temperature is above 20 degrees, the air conditioner cannot heat normally, which is easy to cause protection. The fourth is that the failure of the indoor fan does not blow the wind and protects the shutdown.

If the outdoor fan fails, causing serious frosting, defrost is carried out, and the indoor air prevention function is entered. The fifth is that the starting capacitor of the compressor fails, and after a period of operation, the starting capacitor fails and short-circuits, causing the compressor to stop running. Hope it helps!

This is normal.

However, the indoor unit is not stopped. The so-called low-frequency operation means that when the load of the machine is not large, the unit will self-adjust and change the speed of the press, which is what we call low-frequency operation. However, this does not stop the operation of the gauge unit after the load is reached;

When refrigeration, when the indoor temperature is higher than the set temperature, it will start, at this time it is a low-frequency operation, but when the temperature difference is large, the frequency will rise, and when the temperature reaches the set temperature, it will start to reduce the frequency until the temperature is reached, then the external machine press will be stopped, but the internal machine will be running all the time.

In theory, the inverter air conditioner (laboratory) does not stop, but in our actual environment, due to the difference in set temperature, voltage, current, and ambient temperature, the external unit may be shut down.

My Hisense full DC inverter air conditioner is also like this(35GW 12FZBP-3),When the compressor lights go out at the set temperature, it stops running,But after I tested my air conditioner, the minimum current of the compressor when it reached the set temperature is,That is, about 460W,There has never been150W-400WThe minimum power,I feel that I was deceived by Hisense,Domestic goods can not be supported by expensive and cheap products,Alas。

The compressor does not stop running after the inverter air conditioner starts, but the compressor speed is fast during the period from starting to reaching the temperature you set, and after reaching the set temperature, the compressor runs at low frequency and the speed is slow.

Summary. 1.Pressure switch fault:

When the pressure of the air conditioning system is too high or too small, the pressure switch will automatically power off for protection, and the press will stop running. If the pressure switch fails, it can cause the press to stop running prematurely. 2.

Condenser failure: The condenser is the part of the high-temperature and high-pressure gas released by the compressor that becomes a high-pressure liquid after being cooled. If the condenser fails, it can cause the press to stop automatically after 15 minutes of heating.

3.System refrigerant: Insufficient refrigerant in the air conditioning system can cause the press to overheat, activating a protection mechanism to stop the press.

4.Faulty circuits: Faulty circuits can cause the aircon to not work properly or even damage the equipment.

If there is a problem with the air conditioning circuit, it may cause the compressor to automatically stop operating after a period of operation. 5.Other failures:

Other components in the air conditioning system, such as sensors, controllers, etc., can also cause the press to stop running prematurely.

Dear, I would like to disturb your <>

<> Hai Chongxin 3 hp inverter vertical crack annihilator air conditioner heating 15 minutes press stopped, may be caused by the following reasons:

1.Pressure switch failure: When the pressure of the air conditioning system is too large or too small, the pressure switch will automatically turn off the old alarm protection, and the press will stop running.

If the pressure switch fails, it can cause the press to stop running prematurely. 2.Condenser failure:

The condenser is the part of the high-temperature and high-pressure gas released by the compressor that is cooled and turned into a high-pressure booster liquid. If the condenser fails, it can cause the press to stop automatically after 15 minutes of heating. 3.

System refrigerant: Insufficient refrigerant in the air conditioning system can cause the press to overheat, activating a protection mechanism to stop the press. 4.

Faulty circuits: Faulty circuits can cause the aircon to not work properly or even damage the equipment. If there is a problem with the air conditioning circuit, it may cause the compressor to automatically stop operating after a period of operation.

5.Other faults: Other components in the air conditioning system, such as the amplifier sensor, controller, etc., can also cause the press to stop prematurely.

Hisense inverter air conditioning compressor does not start,Fan is running normally,What's going on。

Hisense inverter air conditioning compressor does not start,The fan is running normally,What's going onHello dear,<>1、Long-term operation under the lack of Freon。 System leakage is the root cause of refrigerant deficiency due to improper installation. The workaround is:

Replenish freon for air conditioners. 2. It is an electrical line fault. The workaround is:

Check and repair, the differential pressure relay is disconnected, the high voltage disconnect is disconnected, press the differential pressure relay reset button down and wait for the pressure change to close the contact or readjust the disconnection pressure. Precautions for maintenance of inverter air conditioner: 1. Wiring problems of DC inverter compressor:

The three ends of the compressor must be wired according to the wiring diagram according to the identification on the main board and gasket and compressor cover, and the wiring sequence shall not be reversed and the wiring shall not be loosened, otherwise unpredictable consequences will occur. 2. The high-voltage problem of DC inverter controller: the large-capacity aluminum electrolytic capacitor on the motherboard of the external unit and the devices connected in parallel with it (PFC, IPM, voltage divider resistor, etc.) are all devices with high voltage of more than 380 volts, and there is a high-voltage residual voltage after power-off, the residual voltage discharge time is long, it takes a few minutes or even ten minutes to discharge, and the human body cannot contact it before the discharge of these devices, otherwise it will endanger personal safety by electric shock.
