GE air conditioner frequently turns on and off (short cycling)

Safety: Unplug before moving sensors or opening panels.

Steps:

• Check sensor placement: Ensure the room temperature sensor is in the return air path, not directly in the cold air stream. If it is, reposition slightly away from the discharge.
• Clean filter and coils: Restricted airflow can cause rapid temperature swings near the sensor. Clean as needed.
• Verify mode and setpoint: Avoid setting the temperature extremely low; moderate settings reduce cycling.
• Board/thermostat: If cycling is extreme and not related to room size or sensor placement, the control board or thermostat may be faulty and require replacement.
