Dometic ACC3100 display error indicator prep

Use the official Dometic ACC3100 display-error support page to capture which indicator appears before support.

Owner-safe checklist

• Record the ACC3100 model, exact indicator or button state, mode, app state, fan behavior, and when the error appeared.
• Save photos or screenshots of the display, app state, product label, and any visible error indicator.
• Use Dometic, a dealer, or qualified RV ventilation service for repeated errors, mounted parts, installed power, or control decisions.
