Unit frequently starts and stops (short cycling) without reaching set temperature

Safety first: Turn off power before accessing sensors or coils.

• Check settings: Ensure the unit is not set to an extreme temperature and that the mode (Cool/Heat/Auto) is appropriate.
• Clean filters and coils: Dirty components can cause rapid temperature swings near sensors.
• Sensor placement: Verify that the room temperature sensor is in the airflow and not touching the coil or near a heat source.
• Room layout: Avoid placing heat sources (lamps, electronics) directly under the indoor unit.
• Technician evaluation: If short cycling persists, a technician should check refrigerant charge and confirm the unit is correctly sized and configured.
