Unit's fan runs continuously even when the set temperature is reached; compressor cycles normally.

Safety: No internal work is needed for basic checks; unplug before opening the unit.

Steps:

• Check fan setting: On the control panel or remote, set the fan mode to AUTO so it cycles with the compressor.
• Reset controls: Power cycle the unit to clear any temporary logic errors.
• Inspect relay (advanced): If the fan still runs constantly in AUTO mode, the fan relay on the control board may be stuck and the board may need replacement.
