Indoor unit frequently turns on and off (short cycling)

Safety: Turn off power before moving sensors or opening covers.

• 1. Check airflow: Ensure that the indoor unit intake and outlet are not blocked by curtains or furniture.
• 2. Verify setpoint: Avoid setting the temperature extremely low/high; use moderate settings.
• 3. Inspect room sensor: If the room sensor is external or on a wired controller, ensure it is not near heat sources or in direct sunlight.
• 4. Clean filters: Dirty filters can cause uneven temperature sensing.
• 5. If short cycling continues: A technician should check sensor calibration and system sizing.
