Safety first: Disconnect power before handling the control board.

CF indicates a configuration or memory error in the main control board.

Step 1 – Power reset: Unplug the wine cooler for at least 10 minutes to allow capacitors to discharge. Plug it back in and see if CF clears.
Step 2 – Check for recent power events: If CF appeared after a power outage or surge, consider using a surge protector once the unit is repaired.
Step 3 – Inspect control board: Remove the rear access panel and locate the main control board. Look for obvious damage such as burnt components or corrosion.
Step 4 – Reprogramming (technician): Some Café boards can be reconfigured or updated using service tools. This typically requires a factory-trained technician.
Step 5 – Replace main control board: If CF persists and reprogramming is not possible, replace the Café-compatible main control board. Transfer any configuration jumpers or plugs as directed by the installation instructions.

After replacement, verify that all functions (cooling, lights, fans) operate normally.

Wine cooler displays CF and may not respond to temperature changes; some functions may be disabled.
