How to fix Gree E8
Clean the indoor filters
Turn the unit off, remove the filters, wash them, and let them dry before reinstalling.
Unblock the indoor unit
Move curtains, shelves, or anything sitting within a few inches of the intake on top or the outlet at the bottom.
Run it on high fan
Then run the unit on high fan for a while and check that air comes out strongly across the whole outlet.
When to call a technician
If E8 keeps coming back with clean filters and open airflow, a technician should check the indoor fan motor and the refrigerant system.
