Midea aircon E5 error code is the indication of evaporator coil outlet temperature sensor problem. It is either open or short circuited which is causing the unit to stop functioning. If you are using a Midea AC in Singapore, E5 can be a common error code that can flash on the aircon display. Let’s discover the reasons for E5 code on a Midea AC, how to solve it and what are the preventive measure you can take to stop it coming in the future.
What Does E5 Mean in Midea Aircon?
For most Midea split and inverter systems, E5 signals a problem with a temperature sensor on the coil (evaporator outlet or indoor pipe).
This could mean the sensor is open-circuited or short-circuited. This problem will make the unit stop working as it can’t get accurate temperature readings.
Why You See E5 Error Code?
The common reasons for E5:
- Sensor wire is loose, damaged, or poorly connected.
- The sensor itself is faulty.
- In rare cases, the main control board (PCB) has issues .
How to Fix E5 Error Code
If you see E5 error on your Midea AC, follow below steps to solve it:
Power reset
Switch off at the breaker, wait 60 seconds, then restore power. If E5 returns, look further.
Open the indoor unit
Check the sensor wiring for disconnections or corrosion.
Test the sensor
Use a multimeter to check resistance of the sensor. If it’s incorrect or infinite, replace the sensor.
Inspect the PCB
If wiring and sensor are fine but the error stays, the PCB may be failing. Call a technician to repair the PCB.
Call a technician
If you are living in Singapore, hire a BCA‑licensed aircon service provider who is familiar with Midea systems.
Notes For Midea Users in Singapore Having E5 Error
Below are a few key note that the users in Singapore can follow:
- High humidity and round-the-clock use may damage the sensors faster.
- Booking a twice-yearly service is a good preventive measure that you can take.
- If you need a repair, the cost can be:
- Sensor replacement/labour: S$80–120
- PCB repair/replacement: S$200–350
- If you have a Midea service plan or warranty, parts and labour may be covered .
Can You Continue Using It?
No. If you are seeing an E5 code on your Midea aircon, it may not function properly. In most cases, the aircon will freeze up. Otherwise, it may not cool efficiently. In case of this issue, do not continue using the system. Turn off it and follow the fixes I have discussed.
FAQ
Is E5 ever about refrigerant or low gas?
No. That’s not how Midea uses E5. It refers to sensor faults, not refrigerant issues.
Could it be the outdoor sensor?
No. E5 points to indoor coil or pipe sensor problems, not outdoor temperature sensors.
How often should sensors be replaced?
Replace only when tests show out‑of‑range resistance. If you service your unit regularly, sensors will last for years.
Which technician should I call in Singapore?
Look for BCA-registered aircon servicing companies experienced with Midea aircon.
Summary
- E5 means the indoor coil temperature sensor has malfunctioned.
- Fixes include wiring checks, sensor testing, and PCB inspection.
- In Singapore, repair costs are modest and local technicians know how to handle this.
