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

Steps:

• 1. Clean filters and coils: Ensure good airflow to prevent rapid temperature swings at the sensor.
• 2. Check set temperature and mode: Avoid setting the temperature extremely low/high; use moderate settings.
• 3. Inspect room sensor location: For ducted Panasonic units with remote sensors, ensure the sensor is not near supply vents or heat sources.

If short cycling persists and the unit is significantly oversized, there is no simple fix; consult an HVAC professional about zoning or capacity adjustment options.
