May I ask if the new cabinet machine air conditioner will be shut down for ten minutes, and the word

This fault is compressor protection.

There are many reasons for compressor failure, and the following are some personal experiences that I hope will help the landlord.

There are probably several reasons for compressor protection:

1. Compressor overheating:

The compressor is cooled by refrigerant, which may be due to the small amount of refrigerant and poor cooling of the compressor.

It may be blocked, impurities or ice blockage, or leakage of refrigerant.

2. Compressor high-pressure protection:

High-pressure protection is poor condensation from the system point of view.

It may be that the heat exchanger is too dirty, the fan does not rotate, or the ventilation effect of the heat exchanger is too poor.

3. Compressor low pressure protection:

If the refrigerant is less, the specific suction volume of the compressor is small, and the exhaust return pressure will be low.

Poor indoor evaporation, liquid refrigerant can not evaporate completely, resulting in low pressure of the return liquid, this situation is uncommon.

4. Poor compressor lubrication (** air conditioning).

The oil return of the compressor is poor, and the possible reasons include the plugging of the oil hole on the compressor, the plugging of the oil return capillary and the plugging of the oil return hole of the low-pressure tank, etc., and the oil cannot return to the compressor.

In addition, due to poor indoor evaporation, the liquid refrigerant cannot evaporate completely, and the liquid refrigerant will dilute the refrigeration oil, resulting in poor lubrication of the compressor. (This fault will occur if the indoor unit and electronic expansion valve are bad and the power supply is not uniform).

In addition, it is also possible that the system pipeline is too long, the drop is too large, and the low load operation is often carried out, which will cause the compressor to start and stop frequently, and will also lead to poor oil return to the system.

5. Compressor liquid shock.

Poor indoor evaporation, liquid refrigerant can not evaporate completely, back to the compressor to crush the vortex plate.

Summary. There is a new branch air conditioner to protect the shutdown after ten minutes of shutdown, what is the reason for the pro!1. If there is too much refrigerant, the solution is to appropriately reduce the refrigeration dose2. Poor heat dissipation, the solution is to check whether the cooling fan is rotating, whether the condenser pipe has dirt, and clean the condenser3. The pipeline system is blocked, and the solution is to judge and eliminate it with reference to the pressure gauge, and re-treat it systematically4. The evaporator or filter screen is dusty and scaling, and the cause of the failure is because the airflow becomes smaller, and the system pressure and temperature are unstable, and the solution is to clean the evaporator or filter5. Lack of freon, the reason for the failure is that when the lack of freon, the exhaust temperature of the compressor will be overheated, so that the overheating load protection switch trips, and the solution is to find a merchant to add freon.

Hope it helps!

Hello, dear, thank you for your patience, the answer has been found for you, you check it, thank you!

Xinke air conditioning cabinet unit power on ID protection 3, the machine does not start! Ask for a high finger to teach! Thank!

1.The binary solution is heated and boiled by the heat source in the generator to produce refrigerant steam, which is condensed into a refrigerant liquid in the condenser. The liquid coolant is throttled through the U-tube into the evaporator, which is injected at low pressure.

The liquid coolant evaporates and absorbs the heat of the refrigerant, resulting in a cooling effect. The concentrated solution from the generator is cooled and depressurized by a heat exchanger and then flows by gravity into the absorption tower. It is mixed with the original solution of the absorption tower to become a concentrated solution of intermediate concentration.

The intermediate concentration solution is pumped in by the absorption tower and sprayed to absorb the refrigerant vapor coming out of the evaporator to form a dilute solution. The dilute solution is pumped from the generator to the generator, and then the refrigerant vapor is generated by the heat source to form a concentrated solution and enter the next cycle.

There is a Xinke air conditioner that is turned on for ten minutes to protect the shutdown What is the reason 1The temperature controller of the indoor unit may be damaged. Open the housing of the indoor unit, and there is a copper sleeve 3-4cm long on the copper tube coil, which is stuck in the tube temperature sensing head.

The outdoor unit is installed on the power grid, or there is a blockage around it, and the ventilation is poor, resulting in protection shutdown. The starting capacitor of the cooling fan of the outdoor unit is damaged, the fan is not running, and the temperature is too high, which cannot protect the machine. You can see it with the naked eye.

4.If the fan is not working, replace the fan starting capacitor. Most of the refrigeration is buried in economic leakage, the refrigeration capacity of the air conditioner is greatly reduced, and the machine is easy to overheat.

The noise of the air conditioner noise leaking from the refrigerator is easy to identify. Ask the repairman to add the refrigerator and check for leaks.

Xinke air conditioner KF-50LWH(F) protection 4 fault 10 minutes after turning on the air conditioner display screen protection 4 failure**, the air conditioner internal and external units shut down.

Fault**: E4 Fault Content: Refrigerant Leakage Protection Fault Cause:

1. Refrigerant leakage. 2. The refrigeration section is not filled with sufficient weighing agent. 3. The control circuit board is faulty, and the ignition hand control signal cannot be received and sent.

It is recommended to find a professional maintenance personnel to check it. Hope it can help you.

1. 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. Air conditioning repair shops have to buy it, a few yuan a piece.

2. The outdoor unit is installed in the grille, or there is a block around it, and the ventilation is poor, resulting in protection shutdown.

3. The starting capacitor of the cooling fan of the outdoor unit is damaged, the fan does not rotate, and the temperature is too high and the protection stops. It can be seen with the naked eye. When the fan does not rotate, replace the fan starting capacitor.

4. Most of the refrigeration leakage is lost, the refrigeration capacity of the air conditioner is greatly reduced, and the machine is easy to overheat. The air conditioner that leaks from the refrigeration economy is obviously much louder than before, and it is easy to identify. Let the master who repairs the air conditioner add the refrigeration and check for leaks.

Overvoltage protection. It is generally caused by the following reasons:

1. The temperature of the external unit of the air conditioner is too high, causing the air conditioner to enter the protection mode. Check the heat dissipation of the air conditioner and whether the exhaust vent is blocked. Avoid direct sunlight.

2. Thermistor failure, thermistor failure leads to temperature induction failure of the internal machine, and the external unit cannot work normally.

3. If the refrigerant is excessive or insufficient, it needs to be checked by a special master.

4. The current and voltage of the air conditioner are unstable.

There are three forms of air conditioning protection: overheating protection, overcooling protection, and overcurrent protection.

1. Overheating protection: the system runs for a long time after the lack of fluorine; The system has a blockage (ice blockage or dirty blockage) for a long time; The ambient temperature is too high; Compressor overheating protection Qi let the device break, overheating protection, as long as the temperature of the compressor is reduced, the wheel can be started, generally can be compressed watering to quickly cool, and then check the cause of its protection.

2. Subcooling protection: the ambient temperature is ultra-low (below minus 15 degrees).

3. Over-current protection: the starter is tolerant of failure; The system lacks and runs for a long time; The voltage is too low; The compressor itself is faulty.

There are three forms of air conditioning protection: overheating protection, overcooling protection, and overcurrent protection. 1. Overheat protection:

After the system is deficient in fluorine, it runs for a long time; The system has a blockage (ice blockage or dirty blockage) for a long time; The ambient temperature is too high; The overheating protection device of the compressor is broken, and the overheating protection can be started as long as the temperature of the compressor is reduced, and the compression can generally be watered to cool down quickly, and then the cause of its protection can be investigated. 2. Overcooling protection: the ambient temperature is ultra-low (below minus 15 degrees).

3. Over-current protection: the starter is tolerant of failure; The system lacks more guesses and runs for a long time; The voltage is too low; The compressor itself is faulty. 1. Anti-freezing protection.

Summary. Reasons: 1. The possibility of mice biting off the sensor wire is more than 60%, especially in public places such as restaurants.

2. The filter screen of the internal machine is dirty and blocked, and the possibility is more than half. 3. The reduction of the capacity of the internal fan leads to the low speed of the internal fan. 4. The back of the evaporator of the internal machine is too dirty, resulting in the evaporator not being ventilated.

5. The sensor resistance value drifts.
