Refrigerator display shows E0 and cooling performance is reduced or intermittent.

Safety first: Unplug the refrigerator before removing any panels or touching wiring. Use a non-contact voltage tester if available.

Step-by-step:

• 1. Power reset: Unplug the unit for 5–10 minutes. Plug back in and see if E0 clears. Many Avanti control boards will clear transient faults after a hard reset.
• 2. Check outlet and voltage: Confirm the outlet is delivering a stable 110–120V AC using a multimeter. Avoid extension cords or power strips.
• 3. Inspect control panel connections: Remove the front control panel (usually held by clips or small screws). Check that all ribbon cables and harness plugs are fully seated and not corroded or burnt.
• 4. Look for moisture: If condensation has entered the control area, dry it gently with a cloth and allow the unit to sit unplugged for 30–60 minutes before reassembly.
• 5. If E0 returns: The main control board may be failing. At this point, replacement of the electronic control board is recommended. Photograph all wire positions before removal.

When to stop: If you see burnt components, melted plastic, or smell burning, do not power the unit again. Contact a qualified technician.
