The Midea aircon E5 error code typically indicates that an open or short circuit is detected in the outdoor temperature sensor or thermistor, more specifically the evaporator coil middle temperature sensor (often denoted as T2 in the official Midea aircon manual) which reads the air side heat exchanger refrigerant outlet temperature. The fault may be in the outdoor thermistor itself, the outdoor PCB terminal and the associated wiring, or your aircon is low on refrigerant gas and needs prompt servicing to maintain the unit’s chosen cooling capacity.
Troubleshooting to clear a Midea aircon E5 error code involves a thorough inspection of the outdoor sub-unit, including checking for the tell-tale ether-like smell of coolant gas leaks that might be behind the low levels of refrigerant gas. The latter odor, if present, should be your cue to call in a service technician.
Switch off the air conditioning unit, unplug it from the power source, and try as much as you are able to access the internal parts of the outdoor unit. Clean any dirt that you see, and carefully check for damage, especially on the outdoor thermistor–which is a black wire with a copper sensor head. Check for loose wiring or severed connections to the PCB mainboard. If all seems clear, plug the AC back in, turn it on, and check if the E5 error code is still displaying. If the error fails to clear after doing these troubleshooting steps, then seek professional help.
RA malfunctioning outdoor thermistor might indeed be the cause of the Midea aircon E5 error display after all. Silverback Aircon, which has a well-maintained collection of refurbished Midea aircon spare parts, can simply put in a working thermistor replacement for the electrically damaged or shorted part.
And, should the damage extend from the wiring connecting the sensor to the outdoor PCB terminal to the mainboard itself, then an outdoor PCB replacement might also be needed to get your Midea aircon to work properly again. Silverback Aircon replaces the full circuit box containing all the outdoor PCBs, in case one of them is found to be damaged. If the model of your Midea condenser unit is M30A21CDN1QC4, then it has three PCBs–the control board, power board, and noise filter. For the Midea condenser unit model MS9A109CRDN1QC4, there are only two outdoor PCBs–control board and power board. To fully clear the E5 error that might be caused by a malfunctioning PCB, Silverback Aircon will install the circuit box containing the set of PCBs matching the specific model of your condenser unit.
The following table itemizes the Midea aircon E5 error-relevant parts and their corresponding pricing.
If the E5 error code is found to be caused by low refrigerant gas levels, Silverback Aircon can also readily provide the solution. Gas top up servicing is just one of the many offerings in Silverback Aircon’s comprehensive aircon servicing options. The table below shows the price ranges for refilling different types of refrigerant gases.
