Dometic ACC3100 outside filter blocked prep

Use the official Dometic ACC3100 outside-filter blocked support page to document the warning before support.

Owner-safe checklist

• Record the ACC3100 model, exact outside-filter warning, airflow symptom, weather, display state, and recent maintenance history.
• Save photos of the visible display, product label, and any owner-visible filter-condition evidence from normal safe access.
• Use Dometic, a dealer, or qualified RV ventilation service for mounted parts, sealing, installed power, or repeated blocked-filter warnings.
