Soleus Air AC turns on and off frequently (short cycling), running only a few minutes at a time.

Safety: Turn off and unplug before moving sensors or opening panels.

• Clean filter and coils: Ensure airflow is not restricted. Clean filters and coils as described in other entries.
• Check sensor placement: Locate the room thermistor behind the front grille. If it is directly in the cold air stream, reposition it slightly so it senses average room air, not just outlet air.
• Verify room size: Compare the BTU rating of your Soleus Air unit to the room size. If the unit is significantly oversized, it may naturally short cycle; consider using a lower fan speed or dehumidify mode.
• Control board: If cycling is extremely rapid (seconds to a minute) and not related to temperature, the control board relay may be faulty and require replacement.
