Midea air conditioner common fault codes need to be distinguished according to different models. When there is an air-conditioning fault code, you can go to the air-conditioning fault code network to inquire, down to the air-conditioning brand and model. The following is a complete list of common fault codes of Midea air conditioner for reference only.
1, R 1/R/S3/S2/S 1 cabinet
P3 high and low voltage protection
(2)E 1T 1 sensor failure.
(3)P4 indoor evaporator protects compressor (high temperature or low temperature)
(4)E2T2 sensor failure
(5)P5 outdoor condenser high temperature protection shuts down the compressor.
(6)E3T3 sensor failure
(7) When the outdoor exhaust temperature of (7)P7 is too high, turn off the compressor (used for frequency converter).
(8)E4T4 sensor failure (for frequency converter)
2. Total health Q 1 cabinet machine
P3 high and low voltage protection
(2)E 1T 1 sensor failure.
(3)P4 indoor evaporator protects compressor (high temperature or low temperature)
(4)E2T2 sensor failure
(5)P5 outdoor condenser high temperature protection shut down the compressor.
(6)E3T3 sensor failure
(7) When the outdoor exhaust temperature of (7)P7 is too high, turn off the compressor (used for frequency converter).
(8)E4T4 sensor failure (for frequency converter)
(9)P8 compressor top temperature protection (frequency converter)
(10)E5 network communication failed (none)
(1 1)P9 Protect against frost or cold wind, and turn off the fan.
(12)E6 outdoor fault
(13)E7 humidifier failure (none)
(14)E8 electrostatic precipitator failure (none)
(15)E9 automatic door failure
3. All-healthy Q 1 type hanging up
Error reading EEPROM parameters when E 1 is powered on.
(2) 2) Errors in E2 Zero Crossing Detection
(3)E3 fan speed is out of control
(4)E4 current protection
(5)E5 indoor room temperature sensor is open or short-circuited
Second, what is wrong with Midea's air conditioner pr?
1, many friends found that Midea's air conditioner was broken and the word pr appeared on the display. In fact, this shows pa instead of pr. Many people misread it and can't find the fault.
2. Generally speaking, Midea Air Conditioning pa means that the air conditioning cabinet door is not in place, so it will jump out of the fault prompt. There are two specific solutions:
Restart the machine, all the magnets on the right side are attracted, and the door will close.
(2) It still doesn't work, that is, the door switch is broken, so call for after-sales repair.
3. In another case, Midea's air conditioner pr is actually displayed as p 12. P 12 is generally caused by too much refrigerant or poor heat dissipation of condenser. If it was good before, it was still the motherboard. The fan parameters of the condenser are not adjusted correctly and do not match the working load of the compressor. It is recommended to ask a professional to repair it.
Third, Midea's air conditioner displays 60 and E alternately.
Midea air conditioner will inevitably break down during use. At this time, the fault code will pop up on the screen, such as 60 and E alternately displayed. What's going on here? Midea's air conditioner shows that alternating 60 and E is an abnormal signal of outdoor unit. The following detection steps are required:
Check whether the compressor winding resistance and running current are normal.
(2) Check whether the high and low pressure are normal when the unit is running.
(3) Check (whether the pipe temperature sensor is normal) whether the line is in good contact with the plug-in on the circuit board, whether the pipe temperature sensor is firmly fixed, whether the evaporation of the indoor unit is good, especially whether the pipe temperature detected by the pipe temperature sensor reaches the cooling or heating temperature.
(4) Check whether the condenser surface is too dirty, and if it is too dirty, clean it.
(5) Check whether the capacitors of outdoor motors and fans are damaged. If damaged, please replace it.
(6) If the above is normal, replace the electric control board.
