Overview
The DA 398-5 is a wall-mounted chimney range hood with a canopy 29 7/16 inches wide and an internal blower listed at up to 625 CFM. It offers four fan levels, and its intensive setting can step back to level three after ten minutes. The lights switch on and off by their own control, so a dark hood with a running fan is a separate fault from a dead fan. This Miele hood can also recirculate air with an optional conversion kit. Across the metro areas we cover, describe whether the airflow or the light has failed, and give the full number from the rating label along with any indicator pattern you see.
The recirculation option is what sets this hood apart from a vent-only model: it needs an optional conversion kit and a charcoal filter, and that filter must be replaced at least every six months or sooner if odors come through. The intensive setting drops to level three after ten minutes so the blower does not stay at full power. Owners who skip the charcoal schedule notice odor returning before any mechanical part fails.
