E1 – High Pressure Protection
Usually caused by poor outdoor airflow, dirty condenser coils, or refrigerant issues. Turn off the unit if the code persists and arrange for inspection.
E2 – Anti-Freeze Protection
Often related to dirty filters or restricted airflow. Cleaning the filters may resolve the problem.
E3 – Low Pressure Protection
Typically indicates refrigerant leakage or low gas pressure. A pressure test is recommended before any gas top-up.
E4 – Temperature Sensor Error
The indoor temperature sensor may be faulty or disconnected. Sensor replacement is usually a straightforward repair.
E5 – Overcurrent Protection
Can result from unstable power supply, compressor problems, or electrical faults. Avoid repeated restarts until diagnosed.
E6 – Communication Error
One of the most common Midea faults. It usually indicates communication failure between indoor and outdoor units caused by loose wiring, faulty PCBs, or power issues.
E8 – Power Protection Fault
Common in commercial and cassette systems. Electrical checks are required to identify wiring or phase-related issues.
Advanced Error Codes
F0 – Refrigerant Leakage
Low refrigerant levels are detected by the system. Leak detection and proper repair are required before recharging.
F1 / F2 / F3 / F6 – Sensor Faults
These codes indicate problems with indoor or outdoor temperature sensors. Most sensor replacements are completed during a single service visit.
F4 – EEPROM Error
The outdoor unit’s memory configuration has been corrupted. PCB repair or replacement may be necessary.
F5 – Outdoor Fan Motor Fault
The outdoor fan is unable to operate normally due to motor or control board issues.
P0 – IPM Malfunction
A fault has been detected within the inverter power module. Professional diagnosis is recommended immediately.
P1 – Voltage Protection
Power supply fluctuations may trigger this error. Electrical inspection may be required if the problem occurs repeatedly.
P2 – Water Drainage Issue
Usually caused by blocked drainage pipes or clogged drain pans. Regular servicing often prevents this problem.
P4 – Inverter Module Protection
Poor ventilation or inverter overheating can trigger this code. Avoid operating the system continuously until inspected.
H6 – Indoor Fan Motor Fault
The indoor fan motor is unable to rotate correctly and may require repair or replacement.
What Should You Do?
- Turn off the aircon if high-severity codes repeatedly appear.
- Clean the air filters for airflow-related issues.
- Perform a power reset by switching off the unit for five minutes.
- Take a photo of the displayed error code before requesting service.
- Avoid repeatedly restarting the system when refrigerant or inverter faults are suspected.
Frequently Asked Questions
Can I reset a Midea error code myself?
Some temporary communication errors may clear after a power reset. Persistent codes usually indicate underlying faults that require repair.
Which Midea error code is most common?
E6 communication errors, E1 pressure faults, and P2 drainage issues are among the most frequently reported problems.
Will using the aircon damage it further?
High-severity faults such as E1, E3, F0, P0, or P4 may cause additional damage if ignored. Switching off the unit is recommended until proper diagnosis is completed.
How long do repairs usually take?
Minor sensor and drainage repairs can often be completed within an hour, while PCB, fan motor, or compressor repairs may take longer depending on parts availability.
