How to repair the Midea air conditioner E52 failure

E52 outdoor coil T3 temperature sensor malfunction.

Causes and solutions for the error of the temperature sensor of the outdoor coil of the air conditioner:

1. Room temperature sensor: mainly detect the indoor temperature, when the indoor temperature reaches the set requirements, control the operation of the internal and external machines, stop the external machine during refrigeration, continue to run the internal machine, and stop after the internal machine blows the residual heat during heating.

2. Indoor tube temperature sensor: It mainly detects the coil temperature of the indoor evaporator, and plays the role of anti-cold wind, anti-overheating protection and automatic temperature control during heating.

3. Outdoor defrosting temperature sensor: mainly detect the temperature of the outdoor condenser coil, when the temperature of the outdoor coil is lower than 6 degrees Celsius for 2 minutes, the internal unit turns to the defrosting state, and when the resistance of the outdoor coil sensor is large, the indoor unit can not work normally.

Maintenance method: 1) The remote control is set incorrectly;

2) The filter screen is not cleaned in time;

3) There are items in the air inlet and outlet of the air conditioner that affect the heating effect, and the refrigeration effect is poor due to the heat source in the room or the large number of people in the room;

4) Poor insulation effect of the room;

5) The indoor power supply voltage is too low, resulting in low air conditioning efficiency;

6) The ambient temperature is too high or too low, resulting in poor effect.

If the above problems are still not solved, please choose professional service personnel to come to the door for testing and processing.

Midea air conditioner E52, what is the situation.

E52 outdoor coil T3 temperature sensor malfunction.

Different styles of Midea air conditioners have different meanings for E5 failures. For inverter air conditioners, the E5 fault of Midea's inverter hang-up refers to the failure of the outdoor temperature sensor or the failure of the outdoor E-side parameters, and the E5 fault of the Midea inverter cabinet refers to the communication failure between the indoor motherboard and the display board.

The failure of Midea inverter cabinet E5 is mainly caused by incorrect connection of indoor and outdoor connection lines, indoor and outdoor communication circuit failures, outdoor electronic control failures, and no power supply.

During the maintenance period, first put the air conditioner power supply, check whether the power supply is electronically controlled outdoors (there is a power indicator electronic control), then check whether the power supply is connected well in the outdoors, then test whether the communication circuit is normal on the indoor and outdoor circuit boards, and finally check whether there is an electronic control power supply in the outdoors.

E5 Midea Inverter Failed Hanger and Inverter Detector need to check for specific errors**: E50 Outdoor E-Square Fault, E52 Outdoor T3 Sensor Fault, E53 Outdoor T4 Sensor Fault, E54 Outdoor TP Sensor Fault, E55 Outdoor Sensor Fault.

During maintenance, if the inverter air conditioner detector shows E50, the outdoor electronic control can be directly replaced for troubleshooting; If it shows that there are other E5 faults, the corresponding sensor can be replaced directly.

Hello dear!

In addition to the following, the following is the <>< of information I found for you to expand related to the combat band

Check the communication line: Connect the communication line between the indoor unit port and the outdoor unit port to see if there is any loose or damaged place, and need to reinsert or replace the damaged Qi Feng parts. Restart the air conditioner:

Try turning off the power on your air conditioner and wait for a while before turning it back on. After rebooting, observe whether there is still an E52 fault on the control panel. Homing Control Board:

If the above two steps do not solve the problem, you can try to open the indoor unit housing of the air conditioner and check whether the control board is completely homed to ensure that the connection is stable and reliable. Contact after-sales service: If the above methods still can't solve the problem, you can contact the after-sales service center of Midea Air Conditioner to seek professional technical support and help.

They can provide you with more specific troubleshooting methods, or arrange for after-sales service personnel to visit your site for inspection and repair. In conclusion, the E52 fault** is usually related to the communication line of the air conditioner, and you can try the above few steps to resolve the issue. If you are unsure of how to proceed or need more in-depth repairs, it is advisable to consult a professional technician for help.

1.First of all, it is necessary to see whether the rental group setting mode on the remote control is correct. In the summer, it should be on refrigeration, and in winter, it should be on heating (snowflake pattern represents refrigeration, sun pattern represents heating, triangle pattern represents automatic, water drop pattern represents dehumidification, fan pattern represents air supply only) If the mode is set correctly, and the air conditioner still can't come, that's for other reasons.

2.The power supply voltage is unstable, and it often fails to reach the normal voltage, especially during the peak of electricity consumption. 3.

Insert the power supply plug of the indoor fan coil into the main board of the indoor unit, and use the AC voltage block of the multimeter to measure the lead voltage of the common end C and the running winding R of the fan in the room. 4.If the knob on the temperature controller is not dialed to the appropriate position, if it is dialed to a higher position, when the power is connected, the temperature in the air-conditioned room has not reached the upper limit of the set temperature (the temperature at the starting point is out of order), and the compressor cannot start running.

5.If the compressor running current is too large, it means that the fault is in the main circuit; If the compressor running current is normal, it means that the fault is in the control circuit. 6.

For the failure of the compressor not to run, you can also forcibly press the contactor to observe whether the compressor can be refrigerated normally. 7.The air conditioner will be short of fluoride after being used for a long time, and the refrigeration effect will be very poor, so it is necessary to add fluoride in time.

8.It can be caused by a lack of fluoride. If the nut at the copper pipe horn is not tightened during the installation of the air conditioner, or the machine has been moved, it may be a lack of fluorine9

Low-pressure relay action, such as insufficient refrigerant in the refrigeration system, resulting in the suction pressure of the compressor is too low, so that the low-pressure relay action stops the operation of the compressor. 10.Regularly maintain and clean the internal and external units of the air conditioner, especially the air conditioner that has not worked for a long time, and must be cleaned first when it is turned on for the first time.
