What is the disease of Midea inverter air conditioner display E1?

1. There is a problem with the compressor. I believe everyone understands a little bit here, because our compressor is the head of the air conditioner. It can be said that the compressor does not move, and the air conditioner naturally does not move.

So the appearance of E1 may also be due to a problem with the compressor of the air conditioner. If there is a problem with the compressor, we have to find a professional to deal with it. 2. The current and voltage are too high, and if our current and voltage are too high at this time, our air conditioner will feel uncomfortable, just like when we are sick.

If the temperature of the person becomes high, we will naturally feel uncomfortable. Our air conditioning was the same. If the current and voltage are too high, E1 will appear at this time, and our air conditioner may burn out and be damaged.

Therefore, it is not recommended to make our air conditioner current and voltage too high. 3. There may be a short circuit inside. When the E1 comes into our air conditioners, we need to think about it.

Why? The air conditioner has a short circuit, which means that there may be a problem with the internal wires of our air conditioner at this time. At this time, Bian Xiao suggested that if you encounter this kind of short circuit problem, you can find a professional to deal with it, because the air conditioner is not better than other electrical appliances.

If it is a short circuit in other electrical appliances, it is relatively easy to deal with. 4. The compressor temperature is too high. At this time, it is not that the compressor is broken, but that its temperature is too high.

This can happen if the temperature is too high. Therefore, when the air conditioner appears E1, you must remember to look at the compressor.

Midea air conditioner E1 is a fault signal, E1: compressor high pressure protection.

If the compressor current is too large, the compressor is overheated, the exhaust temperature is high, and the module is protected, the overload protector should be checked for disconnection and whether the compressor temperature bag is short-circuited.

Midea's E1 troubleshooting method first determines whether the air conditioner fails after running for a period of time or fails when it is turned on, so as to distinguish whether it is a system fault or a circuit fault.

E1 is the high-pressure protection of the compressor, first to determine whether the fault occurs after start-up** or the fault occurs after a period of operation**, if it is a fault when it is turned on**, first open the internal machine, unplug the plug-in key on the OVC, and connect the OVC with the ground wire with another wire, if the failure continues**, it will be displayed as a defective inner plate; If the ** display does not appear, check whether the connection between the OVC and the high-voltage switch is in good contact! If the contact is good, check whether the high-voltage switch itself is on (within normal pressure, the switch is on), if it is not on, the high-voltage switch is damaged, and it needs to be treated!

Or try replacing the power cords for indoor and outdoor connections.

Questions. The internal machine works for a while to show E1, the external machine has not worked, the four cores of the internal and external machines have been replaced, or so, may I ask the master what is going on.

The 220 has entered the outer board.

Solution to the communication failure of the indoor unit and the outdoor unit: 1. Check whether the sensor body line group is broken or broken; Replace if any; 2. Check whether the wiring between the sensor body and the electronic control board is firm and reliable, and adjust it if there is a problem; 3. Use a multimeter to detect the resistance value of the sensor, if the resistance value is 0 or infinity, it means that the sensor is faulty; Otherwise, it can be judged as an indoor motherboard fault.

Communication failure pro.

Questions. The sensor has also been checked, and now only the inner and outer boards are suspected, but it is impossible to determine which board is broken.

In general, it is the inner board pro.

Questions. Okay, thanks, I'll go buy an inner board and try it. You're welcome dear.

The electrical appliance appears E1, E2, F2, E6, U4, etc.**display: this is a fault**, indicating that the electrical appliance is faulty and cannot work normally. Since the faults of each appliance are different, you can take a look at the manual first.

There is generally a fault ** table in it to see if there is such a fault and the corresponding fault prompt. If you can't find it, or there is no manual, you can contact the after-sales service. If the warranty period has passed, or you have no professional maintenance knowledge and do not have the same accessories, you can ask an electrical repair shop to check and repair.

FYI.

Check whether the phase sequence of the outdoor unit is reversed. Generally, there are many problems with newly installed machines.

Turn on the internal unit, unplug the plug button on the OVC, and connect the OVC with the ground wire with another wire, and the solution can be solved.

Check whether the high-voltage switch itself is on (within normal pressure, the switch is on), if not, the high-voltage switch is damaged and needs to be repaired.

Ten years of inverter air conditioner, about ten minutes after turning on the E1 alarm, the fan of the external unit does not turn. It is not good to change the outer board, and it is good to measure the signal line (there are a total of 3 hail lines between the inner and outer machines, 2 are the power supply vertical ridges, and the other is the signal line on the inner board that is n), and the signal line air conditioner is good. Don't take a detour.

The causes of Midea air conditioner E1 failure mainly include abnormal ventilation system, dirty heat exchanger, excessive refrigerant, abnormal pressure detection circuit or abnormal compressor.

Midea's inverter air conditioner shows that the most common problem of E1 is that the communication between the indoor unit and the outdoor unit is not synchronized. Therefore, if the air conditioner runs abnormally for a period of time, it is a general fault, and if there is a system failure or a circuit failure, it means that the Midea inverter air conditioner shows the air conditioning fault **e1, the compressor current of the air conditioner is too large, the compressor is overheated, the exhaust temperature is high, and the module is protected, and the overload protection should be checked.

Common faults of Midea's air conditioners:

1. The air deflector strip of the air conditioner cannot be closed (false fault, this phenomenon is normal), and the Midea air conditioner has an anti-drying function that can be automatically shut down after 10 minutes.

2. The air conditioner shows "full of dust" (error failure, the machine is normal), when the air conditioner runs for 200 hours, the system will remind the user to clean the filter. After cleaning, press the digital display key for 3 seconds to disappear.

3. When the air conditioner is automatically switched on, when the power is turned on, the air conditioner will automatically switch on, and the emergency switch over 90 can be removed.

Compressor problems, if the compressor is stuck, not getting enough refrigeration oil, or the compressor working coil structure is aging, it will cause the compression to not work properly and E1 will occur. If the refrigeration oil is missing, the refrigeration oil can be added, and if the compressor is damaged, it is recommended to replace it with a new one.

If it is because the refrigeration tissue is blocked by dirt. Check whether the branch pipe is blocked, causing the locking pressure to be too high, and the compressor exhaust temperature rises to overheat protection and stops. Treatment: Clean the system, unclog or replace the filter capillary.

If the fins of the outdoor unit of the air conditioner are blocked by stolen objects and cannot operate normally, the heat of the outdoor unit cannot be discharged, resulting in the high-pressure exhaust temperature and protection of the outdoor unit. Solution: To clean the fins of the outdoor unit, it is recommended to use a special fin cleaning agent.

Precautions for the use of inverter air conditioners.

When the inverter air conditioner is in use, avoid turning the air conditioner back and forth. We all know that the inverter air conditioner will intelligently adjust the operation of the compressor after it is turned on, when the room temperature reaches the set temperature, the air conditioner will run at low frequency and save energy, and when the room temperature changes, the air conditioner will refrigerate the heat according to the temperature control induction. If the user turns on and off the air conditioner too frequently in use, then the use of inverter products is undoubtedly no different from the fixed frequency air conditioner.

The outdoor unit of the inverter air conditioner has a microcomputer control board to air the operation of the inverter compressor, so the circuit board is easy to be damaged in a high temperature and humid environment, so the outdoor unit should be installed in a dry and ventilated place to avoid sun exposure and rain as much as possible.

The E1 machine does not rotate when it appears, and it depends on how the master checks and repairs it.

E1 is a communication failure, check the temperature sensing head of the internal and external machine, there is no problem to directly replace the power supply and signal connection line of the internal and external machine, because the quality of the line of the United States is really not very good, there is no short circuit and no open circuit measured by the multimeter, that is, it will be short-circuited after power-on, and it will be normal if it is not energized. I am doing Midea after-sales, and my experience is that there is a leakage and open circuit in the connection line of the internal and external machine, and if the power supply is short-circuited, the fuse will be burned.

It depends on whether your air conditioner hangs up or cabinets.

If the on-hook display shows e1, it means that the indoor and outdoor communication is faulty.

If the cabinet displays E1, it means that the T1 sensor is faulty.

The external unit display light is solid or flashing.

1: Check whether the 2 optocouplers of the external unit are damaged - replace.

2: Check whether the 2 optocouplers of the internal urgency are damaged - replace.

3: Check the signal line, whether the zero line of the live wire is connected incorrectly - re-connect the external unit and the display light is not on

1: Check whether the outdoor power wiring is AC220V, if it is to replace the outer board.

2: Check whether the outdoor power wiring is AC220V, if not, check whether the host electrical is engaged. If it is suction then please check the connecting cable and replace the inner plate if it is not suction kei.

If it still doesn't work.

It is recommended to find a maintenance master.

Hello, I hope to help you When using the air conditioner, when the air conditioner has some faults, the display screen of the air conditioner will show the corresponding fault**, after the failure, we need to detect all aspects of the air conditioner, and eliminate the problems related to the air conditioner before we can find out the direct cause of the failure**, so what is the fault of the Midea inverter air conditioner E1? Midea inverter air conditioner E1 failure** indicates a communication failure. The main reasons for this failure are as follows, it may be that the signal of the air conditioner or the power supply cable is loose or damaged, and the connection cable can be reconnected or replaced with a new one; It is also possible that the motherboard of the air conditioner is faulty, you can use a tool to measure the AC voltage output of the air conditioner, if it does not reach 220V, you can repair the motherboard. Thank you.

The E1 of Midea's air conditioner is a communication failure of the internal unit, which may be due to an open circuit in the connecting line, and the connecting line needs to be adjusted and replaced; It may be that the circuit board is damaged and needs to be replaced; Check the sensor and body cord set for broken skin or breakage, and replace it if so. It may also be that the condenser is too dirty, and you can clean the heat sink of the external unit.

The E1 machine does not rotate when it appears, and it depends on how the master checks and repairs it.

1. The failure of E1 in the frequency conversion of Midea air conditioner ** means that the communication failure between the indoor unit and the outdoor unit.

2. Indoor and outdoor communication troubleshooting methods:

1. Check whether the connecting line is lengthened or whether the connecting line is reliable or damaged, and adjust it accordingly if there is a problem;

2. Check whether there is a 220V AC voltage output in the indoor current loop circuit, if not, it can be directly judged as an indoor electronic control fault;

3. Measure the DC voltage between the position of the terminal block S and N, if the measured voltage has no jump or the jump voltage amplitude is small, it means that it is an indoor electronic control fault; If the measured voltage jump amplitude is large, it means that the outdoor electronic control fault of the air conditioner.
