Possible Causes
Stuck air damper between zones, Failed mixing fan motor, Obstructed airflow by bottles or shelves, Faulty damper control on main board
How to Fix / Troubleshooting
Safety: Unplug the unit before accessing internal airflow components.
- Check loading: Ensure bottles are not blocking vents between zones or against the rear wall.
- Locate damper/mixing fan: On some Summit dual‑zone models, a damper or small fan moves cold air between zones. It is usually behind an interior panel between the compartments.
- Inspect for obstruction: Remove the panel and check for ice, debris, or misaligned foam blocking the damper or fan.
- Test fan/damper: Spin the fan by hand; it should move freely. If seized, replace the inter‑zone fan motor. If a motorized damper does not move when commanded, replace the air damper assembly.
- Control board: If hardware is good but F3 persists, the dual‑zone control board may be at fault.
