Midea E3: the indoor fan is not running at the speed it was told to

Midea's code reference gives E3 as indoor fan speed out of control. The indoor board commands a speed and compares it against the rotation the motor actually reports, and a mismatch beyond what it tolerates raises the code. It says the speed is wrong; it does not say whether the motor, the drive, or something physical caused it. Applies to: Midea residential split air conditioners covered by the Midea online troubleshooting code reference Midea manufactures for many brands as well as selling under its own name, and code sets differ between those programmes even where hardware is shared. This reading applies to Midea-branded residential split equipment covered by the Midea troubleshooting reference. Confirm against the manual issued with your unit. Owner-safe checks: Switch the unit off rather than leaving it attempting to start, since the refrigerant circuit should not run against a stationary indoor coil. | Clean or replace the indoor filters according to the manual, and confirm the outlet louvres are free to move. | Capture a description of any sound that preceded the fault, which setting produced it, and approximately what week it began. Qualified technician: Everything that would confirm this fault, from releasing a jammed wheel to putting a meter on the feedback line, happens with the indoor casing open and is therefore qualified work. | Do not reach through the outlet louvres to turn the fan wheel. The blades and the drive are not designed for that access and the assembly can start without warning.
