Weak cooling
What you see
Weak cooling during normal use. Record when it started, whether it is intermittent, and any display message.
Likely causes
Airflow, drainage, controls and refrigerant conditions need assessment. A temperature difference or ice patch alone cannot establish the cause.
Safe to try
Check the remote mode and settings, room openings and user-cleanable filters according to the manual. Do not climb to an outdoor unit or spray electrical components.
