What is the problem with the subsoiling fixed speed air conditioner showing E6?

1. Frequency conversion cabinet machine.

1. E1 represents that the current in the press is too large, and the temperature sensing package is open.

2. E2 stands for the anti-freezing protection of the internal temperature tube.

3. E3 represents the inner sensor short open circuit.

4. E4 stands for evaporator tube short circuit.

5. E5 communication fails, n and l cannot be reversed.

2. Ordinary cabinet machine.

1. E1 indicates the high voltage protection of the press.

2. E2 indicates internal freeze protection.

3. E3 means low voltage protection of the press.

4. E4 means exhaust temperature protection.

5. E5 means over- and under-voltage protection and low-voltage protection.

3. Common faults**.

E1: Compressor High Pressure Protection.

1. There is an obstacle in front of the condenser.

2. Start refrigeration when the outdoor ambient temperature is higher than 43 degrees.

3. The control loop is abnormal.

4. The pressure of the high-pressure pipe is over-pressed, and the high-pressure switch is activated.

E2: Compressor low pressure protection.

1. Insufficient refrigerant.

2. The expansion valve is half-blocked, and the solenoid valve is faulty.

3. The filter is half blocked.

E3: Evaporator anti-freeze protection.

1. The indoor fan does not rotate or the tuyere is blocked.

2. The indoor environment temperature is lower than 18 degrees.

3. The plug of the air conditioner temperature sensor tube is broken.

4. The air conditioning control circuit is abnormal.

5. The plug of the temperature sensor tube is not plugged in properly.

E4: Compressor exhaust pipe temperature is too high protection.

1. Aging of compressor.

2. The system is blocked.

3. The heat dissipation of the external unit is not good.

E5: Overcurrent protection.

1. Air conditioner display E6: communication failure.

2. Communication troubleshooting methods:

1. Check whether the display board connection line group is broken or damaged, and check whether the plug connector of the display board connection line group is good, if there is a problem, replace or adjust it accordingly;

2. Check whether there are obvious welding quality problems in the welding of the circuit components at the bottom of the electronic control motherboard or display board, and replace them accordingly if they exist;

3. Use a cabinet indoor display board that can work normally to replace the original faulty cabinet indoor display board, if the air conditioner is still faulty, it is judged that the main board of the air conditioner is faulty; If the air conditioner failure disappears, it means that the display board of the air conditioner unit is faulty;

4. Use a cabinet indoor motherboard that can work normally to replace the original faulty cabinet indoor motherboard; If the air conditioner fault disappears, it is judged that there is a fault in the main board of the air conditioner; If the communication between the motherboard and the display board is still faulty in the air conditioner, it can be judged that the air conditioner display board is faulty.

Summary. Treatment method: First, first clean the filter screen of the air conditioner unit with water and clean the fin evaporator of the air conditioner unit with a mild air conditioner cleaning agent. Second, after cleaning, install the filter, wait for ten minutes, and then turn on the air conditioner, if it still shows e6, then find the manufacturer and after-sales during the warranty period, if it exceeds the warranty period to find a professional air conditioning master for maintenance (for example, in Shaoxing Yuecheng District, Keqiao District, you can generally consider going to Shaoxing e online to find their ** record professional air conditioning maintenance master), report for repair or after the warranty period to find the master to repair, tell him, your air conditioning brand, and tell him that the air conditioner shows E6.

Air conditioner fault E6 generally means that the main board control system of the indoor unit cannot detect the rotation of the indoor unit's fan. The fault analysis is mainly as follows: First, the capacitance of the internal fan is broken.

Second, the motor of the internal Chunshen fan is broken. Third, the motherboard of the internal machine or a part of the motherboard is broken (most likely the thyristor of the main curved board of the internal machine is broken).

Treatment method: First, first clean the filter screen of the air conditioner unit with water and clean the fin evaporator of the air conditioner unit with a mild air conditioner cleaning agent. Second, after cleaning, install the filter, wait for ten minutes, and then turn on the air conditioner, if it still shows e6, then during the warranty period to find the manufacturer and after-sales, if the warranty period exceeds the warranty period to find a professional air front which master to repair (for example, in Shaoxing Yuecheng District, Keqiao District, you can generally consider going to Shaoxing e online to find their ** record professional air conditioning maintenance master), report for repair or after the warranty period to find the master to repair, tell him, your air conditioning brand, and tell him that the air conditioner shows e6. If your air conditioner is owned by the landlord of the chain, please contact the landlord first, and ask the master to repair it under the witness of the landlord, because if the maintenance is beyond the warranty, it will cost a certain amount of money.

Summary. Dear, hello I am very happy to answer your questions,, How to solve the E6 problem of Panasonic air conditioner, A: Cause of E6 failure of Panasonic air conditioner:

Failure of indoor unit or outdoor unit. Fault phenomenon: prompt E6 fault**, the air conditioner does not work, does not start, etc.

Workaround:1There is less refrigerant, and the internal machine freezes.

2.The pipe resistance increases during refrigeration. 3.

The filter is too swollen, including the inner fan blades as well as the evaporative gas. 4.The speed of the internal fan is too slow.

Panasonic Air Conditioner is an air conditioning brand owned by Panasonic Electric Industry Co., Ltd., and its founder is Mr. Konosuke Konosuke Matsushita, who is known as the "God of Management". Since its establishment in 1957, Panasonic Air Conditioner has become a well-known and reputable air conditioning brand in the world. Up to now, Panasonic Air Conditioner has three production bases around the world:

Kusatsu Panasonic Air Conditioner Business Headquarters in Japan, Panasonic Air Conditioner Ashiyuan Device in Malaysia and Panasonic Air Conditioner in Guangzhou.

The failure of the Panasonic air conditioner E6 usually refers to the failure of the outdoor source resistant machine. E6 failure** can be caused by a variety of causes, including but not limited to the following: Refrigerant leakage:

Refrigerant leaks can cause abnormal system pressures and trigger E6 failures**. Outdoor Fan Failure: Outdoor Fan Failure may cause the outdoor unit to fail to function normally, triggering an E6 fault**.

Electronic Expansion Valve Failure: A failure of the Electronic Expansion Valve may result in abnormal refrigerant flow, triggering an E6 failure**. Board Failure:

The circuit board may cause the outdoor unit to not work properly, triggering an E6 fault**. If your Panasonic aircon shows an E6 fault**, it is recommended that you contact a professional aircon repairer for inspection and repair. They can determine the specific cause of the failure by checking the fault** and the corresponding fault phenomenon, and carry out the corresponding repairs and replacement parts.

1) If the communication fails, check whether the black connection cable with the outdoor unit is loose;

2) Check whether the display board connection line group is broken or damaged, and check whether the plug joint of the display board connection line group is good;

3) Check whether there are obvious welding quality problems in the welding of low circuit components of the electronic control motherboard or display board;

4) E6 means that the air conditioner is too dirty;

5) Crash; 6) The signal line of the internal and external machine is broken or leakage;

7) The circuit board is broken.

Second, Panasonic air conditioning failure**.
