What to check

  • Set the remote to Cool and choose a temperature below the room temperature. Check whether other heads on the same outdoor unit are set to a conflicting mode.
  • Check accessible indoor filters and follow the owner’s manual for cleaning. Look for leaves or other obstructions around the outdoor unit from ground level.
  • Photograph the model label and record any error code before changing settings. Note whether one room or every room is affected.

When to stop

Turn the system off if you see indoor water near wiring, smell burning or notice repeated breaker trips. Leave covers, wiring and refrigerant connections to a technician.
