Outdoor EEPROM Error
What it means
This code appears on Midea split air conditioners with the classic code set when the outdoor board cannot read operating data from its EEPROM memory chip, so the outdoor unit will not run. The meaning may differ on some Midea series, so check the unit manual; it can also mean something else on other brands.
Models covered: Midea residential split air conditioners with the classic display codes (E0–EC, F1–F4, P0–P4); newer Midea series use different codes (EH, EL, PC) and some models differ.
Symptoms3
- The outdoor unit does not run while the indoor fan runs with no cooling.
- The code sometimes appears after a power cut or fluctuation.
- Changing settings on the remote does not clear it.
Possible causes4
- Temporary memory fault after a power cut or voltage surge.
- Failed memory chip on the outdoor board.
- Moisture or conductive dust on the outdoor board.
- General outdoor board failure.
How to diagnose4
- Switch off at the breaker for several minutes, then restart.
- Check the supply is stable, especially if the code follows power cuts.
- After confirming the board is discharged, the technician inspects the outdoor board for moisture or burning.
- If the code stays, the technician replaces the outdoor board with one matched to the model number.
How to fix4
- Restart after a few minutes with the power off.
- Clean and dry the outdoor board and close the electrical box cover properly.
- Replace the outdoor board with a matching part at a service center.
- Fit a voltage protector to prevent repeats, then confirm the outdoor unit runs without the code.

Frequently asked questions
What is the difference between E0 and F4?
E0 concerns the indoor board memory, while F4 concerns the outdoor board memory, so the place to check and the replacement part differ.
Do I need a genuine board?
It must match the model number and capacity, because the memory data sets how the compressor is driven.
