What is the reason for the appearance of the Midea air conditioner E6 and how to solve it

If the error **E6 air conditioner is faulty, it may indicate a problem with indoor and outdoor communication. The solutions to indoor and outdoor communication problems are as follows:1

First, check the voltage of the external device. 2.Check the voltage of the internal unit.

3.Check whether the communication signal lines between the internal and external units are in poor contact or open circuits. 4.

Reset the aircon thermostat. Turn off the air conditioner on the thermostat, find your circuit breaker box, reset the circuit breaker on the air conditioner unit, and wait 30 seconds. Turn on the aircon thermostat again.

Other common faults of air conditioner 1, circuit breaker or fuse failure When encountering an air conditioner failure, the first thing to check is the circuit breaker and fuse. If you need to replace the fuse or reset the circuit breaker, let the system cool down for 15 minutes first. 2.

Refrigerant leaks: If the refrigerant level is not suitable, the air conditioner may not be working properly. Since refrigerants are harmful to the environment, any leaks need to be repaired and refilled by a licensed technician. 3.

The freezer coil is cleaned regularly or the air filter is replaced to keep the piping system clean. A dirty air filter or a clogged ductwork can cause problems with air flow in the system, which can cause the coil to freeze. You can check for frost on or around the coil by visually inspecting the device.

<> Midea air conditioner E6 refers to the protection failure of the outdoor unit, that is, the system or hardware of the outdoor unit cannot work safely. It is recommended to check whether the wiring of the outdoor unit is normal, and check whether the wires and hardware are obviously damaged. After that, you can turn on the power supply to see if the speed of the outdoor unit is normal, if not, it is likely to be a power problem or poor heat dissipation.

This answer only applies to Midea's KFR-26GW BP2DN1Y-K(3).

1.The fault of E6 in the fixed frequency cabinet machine means that the electrostatic precipitator itself or the connection line is damaged, and whether there is too much dust on the surface;

2.In other commercial cabinet machines appear E6, so let this obstacle ** meaning that the communication signal between the indoor unit and the outdoor unit is abnormal, and the power supply can not be added to the outdoor slip or outdoor unit control motherboard, to check whether the connection line between the indoor unit and the outdoor unit is mismatched or poorly contacted, and pay attention to check whether the phase line and the neutral line of the air conditioner power supply line are reversed.

Midea air conditioner shows that E6 is abnormal electrostatic precipitator, to detect whether the electrostatic precipitator itself or the connection line is damaged, whether there is too much dust on the surface, you need to find the outdoor unit, and check whether the outdoor unit has obvious problemsRestart the air conditioner after adjusting the external factors of the outdoor unit to the best, and check whether the wiring of the outdoor unit is normal, and whether the wires and hardware are obviously damaged.

The air conditioner shows that the E6 is faulty** means different things on different models:

1. The fault of E6 in the fixed frequency cabinet machine means that the electrostatic precipitator itself or the connection line is damaged, and whether there is too much dust on the surface should be detected.

2. The fault of E6 in other commercial cabinets means that the communication signal between the indoor unit and the outdoor unit is abnormal, and the power supply cannot be added to the outdoor or outdoor unit control motherboard, so it is necessary to check whether the connection line between the indoor unit and the outdoor unit is mismatched or in poor contact, and pay attention to check whether the phase wire and the neutral line of the power supply line of the air conditioner are reversed.

Midea air conditioner common faults**:

E1 Indoor and outdoor unit communication failure.

There was an error in the E2 zero-crossing detection.

The speed of the E3 fan is out of control.

E4 Thermal Fuse Break Protection.

E5 Outdoor Temperature Sensor Failure.

E6 Faulty room temperature sensor.

P0 module protection.

P1 Voltage over or under protection.

p2 compressor top temperature.

The solution of Midea** air conditioner E6? 1.First of all, we should check whether the indoor temperature sensor has open circuits, short circuits and poor contact, and there should be thousands or tens of thousands of ohms of resistance and mitigation values.

If not, there must be a fault. Outdoor unit protection If it is a three-phase electric wrong phase, it will be no problem to adjust it, if not, it may be a serious lack of fluorine is the outdoor unit protection, generally check whether the system lacks refrigerant, external envy machine power supply, external machine motherboard, indicating that the indoor temperature sensor is open or short-circuited. Let's see if the indoor temperature sensor is not plugged in tightly, confirm that the simple oak is plugged in, and use a multimeter to measure the resistance value, which is generally about 10k, otherwise there is a problem.

Midea's air conditioner display**E6 means: the indoor evaporator temperature sensor is open or short. Midea air conditioner shows the meaning of the fault **:

1. E1: Error reading EEPROM parameters during power-on 2, E2: Error in zero-crossing detection 3, E3:

Fan speed runaway 4, E4: Quadruple current protection 5, E5: Indoor room temperature sensor open or short circuit 6, E6:

The room evaporator temperature sensor is on.

As follows:

1. All Health Q1 hang-up: Midea air conditioner failure**E6: Fixed-frequency side IOL, OL circuit, power supply phase sequence error.

2. Healthy and Calm Star T3 hang-up: Midea air conditioning failure **E6: outdoor failure.

3. R1 R S3 S2 S1 cabinet machine: Midea air conditioner failure **E6: outdoor protection.

4. Polaris S-type cabinet machine: Midea air conditioner failure**E6: indoor temperature sensor failure.

5. Zhixing R-type inverter cabinet: Midea air conditioner failure**E6: indoor temperature sensor failure.

Midea air conditioner common faults**:E1 Indoor and outdoor unit communication failure.

There was an error in the E2 zero-crossing detection.

The speed of the E3 fan is out of control.

E4 Thermal Fuse Break Protection.

E5 Outdoor Temperature Sensor Failure.

E6 Faulty room temperature sensor.

P0 module protection.

P1 Voltage over or under protection.

p2 compressor top temperature.

E6 error** usually indicates a communication failure of the outdoor unit. Possible causes include:

1.The communication line between the outdoor unit and the indoor Sakura machine is faulty.

2.The circuit board of the outdoor unit is faulty.

3.Outdoor alert first sensor malfunction.

Workaround:1Check whether the communication line between the outdoor unit and the indoor unit is properly connected.

2.If the communication line is normal, it may be a fault of the circuit board of the outdoor unit. It is recommended to contact a professional technician for repair or replacement.

3.If the sensor of the outdoor unit is faulty, the sensor needs to be replaced. It is recommended to contact a professional technician for repair or replacement.

It is caused by the opening of the high-pressure pressure protection of the external unit of the air conditioner. When this happens, it is good to clean the filter of the air conditioner, which is to disturb the air conditioner to better dissipate cold and heat dissipation, and avoid causing pressure on the external machine. Before cleaning the filter, unplug the socket to avoid electric shock.

Hello, what model do you have? It is recommended to unplug the power supply and re-power it to use, if it cannot be ruled out, it needs to be checked and processed after sale.
