Unit turns on and off frequently (short cycling), running only for a few minutes at a time.

Safety: Unplug the unit before moving sensors or cleaning.

• Check room size: Confirm the BTU rating is appropriate for the room. An oversized unit will reach setpoint quickly and cycle often.
• Clean filter and coils: Ensure unrestricted airflow to prevent evaporator icing and protective shutdowns.
• Sensor placement: Locate the room thermistor behind the front grille. If it is directly in the cold air stream, reposition it slightly away so it senses room air, not discharge air.
• Adjust setpoint: Set the temperature a bit higher to reduce cycling.
• Sensor/control issues: If cycling remains extreme, the thermistor or control board may be faulty and should be tested and replaced as needed.
