Midea Air Conditioner EH 00 Error Code
Indoor board memory (EEPROM) fault on Midea air conditioners.
MideaAll Midea air conditioner codes
The indoor control board couldn't read the settings stored on its memory chip (EEPROM). A one-off glitch after a power interruption can clear with a reset, but if it keeps happening the board likely needs service or replacement.
Compatible models
Mini-split models that use Midea's four-character codes. No model list is published for EH 00; your owner's manual will confirm it.
Also shown as
E0 on older displays. EH 0A is a closely related indoor EEPROM parameter error, and EC 51 is the same kind of fault on the outdoor unit's board.

How to fix Midea EH 00
Cut power for 5 minutes
HVACDirect suggests 2 to 5 minutes off at the breaker for this one. A single bad memory read sometimes clears that way.
Note when it comes back
If EH 00 returns the moment the unit powers up, the board is the likely problem. Pass that on along with the model number.
When to call a technician
If EH 00 (or EC 51) shows again after a reset, the board needs to be checked or replaced by a technician.
