Unit frequently turns on and off (short cycling) without reaching set temperature.

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

Steps:

• Check sensor location: Ensure the room sensor is not directly in the cold air stream from the outlet. On some Blaupunkt models, repositioning the sensor slightly away from the outlet can help.
• Improve airflow: Remove obstructions around the indoor unit so air mixes well with room air.
• Clean filters: Dirty filters can cause uneven cooling and rapid cycling.
• Capacity check: If the unit is significantly oversized, consider adjusting setpoint and fan speed to reduce cycling, or consult an HVAC professional about zoning or resizing.
