Safety: Disconnect power before opening any control housings. Avoid touching live circuits.

Steps:

Power reset: Unplug the freezer for at least 10 minutes to allow capacitors to discharge. Plug back in and observe if E6 clears.
Inspect for moisture: Check around the control panel and main board for signs of condensation or water damage. Dry the area thoroughly and correct any source of leaks (e.g., door gasket issues causing condensation).
Check wiring harnesses: Ensure all connectors to the control board are fully seated and free of corrosion or burn marks.
Surge protection: If the error followed a storm or power event, the board may be damaged. Consider using a surge protector for future protection.
Replace control board: If E6 persists after reset and inspection, replace the main control board with the correct Avanti part number for your model.

Warning: Do not attempt to repair the PCB at component level unless you are trained in electronics; replacement is the standard remedy.

E6 error on Avanti freezer; unit may not respond to keypad inputs or may lock up.
