The sensor on the cold coil inside the portable is giving a bad reading. Without it the unit can't tell when the coil is about to ice up, so it stops.

Also shown as

How to fix Midea E2
Let the coil thaw
If the unit was running hard in a humid room, unplug it and leave it off for an hour so any frost on the coil can melt.
Restart with a clean filter
Rinse the filter, let it dry, refit it, and start the unit again.
When to call a technician
A code that keeps coming back needs a sensor replacement by Midea service.
