The Midea codes on this page, grouped by failure type.
Temperature Sensor — Midea
These codes indicate a sensor that’s no longer returning a consistent value. The fault almost always comes from the sensor itself or its connector, rarely from the unit.
Code E4Medium severityair-to-air
Indoor room temperature sensor fault

Fan — Midea
The fan moves heat in or out of the unit. If it’s blocked or failing, pressure rises and triggers a shutdown.
Code E3Medium severityair-to-air
Indoor fan speed out of range
Possible causes
- Faulty fan motor
- Fan blade blocked by a foreign object
- Faulty hall speed sensor
- Very dirty filters restricting airflow
What you can check

Compressor — Midea
The compressor is the central and most expensive part. These codes protect the unit by shutting it down before damage occurs: never force repeated restarts.
Code P4Critical severityair-to-air
Compressor malfunction (drive)
Possible causes
- Compressor seized or struggling
- Faulty inverter module
- Unbalanced pressures at startup
What you can check
- Cut power for 1 hour, then attempt a single restart
Affected models: Blanc, Xtreme Save, All Easy Pro, Breezeless

General fault — Midea
These codes don’t point to a specific part: the unit is signaling that an internal safety feature has been triggered.
Code E2Medium severityair-to-air
Zero-crossing detection fault
Possible causes
- Faulty indoor PCB board
- Unstable power supply
- Disturbed mains waveform
What you can check
- Check the supply voltage
