What should I do if there is an E4 in the new air conditioner?

As soon as the air conditioner is turned on, there will be an e4 failure**, and 1 accessory will be repaired without changing.

Air conditioning failure wheel to do ** e4 may be the air conditioner condenser is dirty, indicating that the resistance of the air conditioning compressor and its current is abnormal, the treatment needs to replace the refrigeration oil or directly replace the compressor, clean the system, replace the refrigeration oil, replace the filter capillary refrigerant, etc., clean the fins with a special fin cleaning wax and balance lotion, replace the capacitor, fan capacitor, fan blade, etc. Solution: Replace the refrigeration oil or directly replace the compressor, clean the nuclear system, replace the refrigeration oil, replace the filter capillary and change the refrigerant, etc., clean the fins with a special fin cleaning agent, replace the capacitors, fan capacitors, fan blades, etc.

How to see the problem from the air conditioner failure**: The temperature of the E1 exhaust pipe is too high. E2 compressor overcurrent.

The E3 power supply is in the wrong phase. The E4 system pressure is too high. The E5 system pressure is too low.

E6 anti-freeze protection. F1 Refrigerated Evaporator Sensor Short Circuit or Open Circuit. F2 Ambient Temperature Sensor Short Circuit or Open Circuit.

F3 Cold Storage Space Sensor is short-circuited or open-circuited. The F4 cryo temperature sensor is short-circuited or open-circuited. F5 minus 7 degree temperature sensor short circuit or open circuit.

Hello dear! We'll be happy to answer for you. What is the filial piety fault of Xinke air conditioner E4?

Answer: Hello dear, the air conditioner displays E4, which means that the compressor exhaust temperature sensor is faulty, and the possible reasons are as follows: 1. The exhaust stuffy code temperature sensor is faulty.

2. Lack of fluorine in the system (the pressure required for heating in winter, if the refrigerant is insufficient, the compressor will work aggravated, and the tube temperature will be overheated, thus showing E4). 3. If the system is dirty or the heat dissipation is not good, it is recommended to clean the filter screen of the internal machine and the condenser of the external machine.

Fault **e4: Low voltage overcurrent protection.

Reasons for the occurrence and how to fix it:

1. The power supply voltage is lower than that of 187V. At present, air conditioners are designed with wide power supply, but if it is lower than this number, the air conditioner cannot be started.

2. For the protection caused by the inner filter screen and the condenser of the external machine being too dirty, it is recommended that Yinweihe clean it first.

3. If the control board is faulty, replace the control board Check whether the voltage is normal first, if it is unstable, it is recommended to install a voltage regulator.

The main reason for Xinke air conditioner E4 is that the Yuchunliang filter of the evaporator is blocked, resulting in poor evaporation effect, as long as the filter screen of the evaporator is cleaned and cleaned, the specific operation steps are as follows:

1. Turn on the air conditioner panel.

2. Pull and hold the air conditioner filter.

3. Remove the air conditioner filter.

4. Clean the air conditioner filter.

5. Replace the air conditioner filter.

Precautions: 1. Handle with care during operation and do not damage the filter.

2. Do not clean the position inside the filter, if it is too dirty, you need to ask a professional to do it.

There are several possibilities: either the refrigeration night is not enough, or the wiring between the internal machine and the external unit is not normal, or the temperature sensor in the internal machine, in general, the possibility of the sensor is relatively large, and it is necessary to adopt it.

There are 2 faults.

1. Check whether the condenser heat dissipation network is very dirty, the heat dissipation effect is poor, and it needs to be cleaned.

2. The capillary tube or filter drier is clogged and needs to be repaired and replaced. After these two problems are eliminated, there is basically no problem.

2. Do not clean the inside of the filter, if it is too dirty, you need to ask a professional.

The fixed-speed hang-up display E4 means: four current protection, and the frequency conversion hang-up display E4 means: the temperature fuse is disconnected protection or the communication between the main control and the display is faulty. If the cabinet shows E4, it means that the T4 sensor is faulty.

Solution: 1. Low voltage.

2. Long-term low-load operation, resulting in poor cooling of the press.

3. Refrigerant leakage leads to poor cooling of the unit.

4. The unit lacks oil.

5. Temperature switch problem.

6. Thermal fuse break protection.

7. It is recommended to check whether the plug-in is loose and whether the circuit board is soldered.

8. If all of the above are normal, the computer board is broken.

1. Check whether the condenser heat dissipation network is very dirty, the heat dissipation effect is poor, and it needs to be cleaned.

2. The capillary tube or filter drier is clogged and needs to be repaired and replaced. After these two problems are eliminated, there is basically no problem.

Summary. Hello, Xinke air conditioner shows that the E4 is the compressor current is too large. Check whether the condenser heat dissipation net is dirty, the heat dissipation effect is poor, and it needs to be cleaned.

If the compressor does not start, then check whether the wiring of the compressor has been burned out. Pay attention to whether your external unit is in a ventilated place, once the external unit overheats, the compressor will actively shut down for protection.

Check whether the condenser heat dissipation net is dirty, the heat dissipation effect is poor, and it needs to be cleaned. If the compressor does not start, then check whether the wiring of the compressor is a shed and whether it has been burned out.

I hope mine is helpful to you.
