Midea Air Conditioner EH 03 Error Code

Indoor fan speed out of range on Midea air conditioners.

EH 03

Moderate DIY

The board told the indoor blower to run at a set speed and the fan didn't get there. Blocked vents can slow it down. If the airflow path is clear, the fan motor itself is the usual suspect.

Compatible models

Wall-mounted Midea mini-splits with the four-character display, as listed on Midea's own code sheets. Check the code table in your manual.

Also shown as

Shown as E3 on older Midea mini-splits. EH 02 is a related zero-crossing signal fault, which Midea says doesn't apply to units with a DC indoor fan motor.

Safety first: unplug the air conditioner (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Midea EH 03

Clean the filters
Switch the unit off, lift the front panel, and slide out the mesh filters. Rinse them in lukewarm water, let them dry fully, and put them back.
Clear the vents
Move curtains or furniture away from the intake grille and louvers, and take anything stored on top of the indoor unit off it.
Run it on high fan
Once it's back on, run the unit on high fan for a few minutes and listen. Grinding, squealing or a fan that never speeds up points to the motor.

When to call a technician

If you hear grinding or squealing from the indoor unit, or EH 03 comes back with clean filters, call a technician to check the fan motor and blower wheel.
