HRV46
Dacor HRV46 Heritage Vent Repair
Most common issues on this model
- Raised vent that stops partway
- Filters that are overdue for cleaning or replacement
- Weak airflow from the blower
- Switch or lift motor that does not respond
The Dacor HRV46 is a 46-inch electric raised downdraft vent from the Heritage line. It is installed behind or beside a Heritage range or cooktop and rises when you cook. Dacor lists the MRV3015-ERS, MRV36-ERS and MRV48-ERS vents in the same family.
Filters get most of our attention on this unit. The metal grease filters are meant to be cleaned about every 8 to 10 weeks, and the carbon filter is replaced somewhere between 3 and 12 months depending on how much you cook. When an owner reports weak airflow, an overdue filter is often the whole story, so we check it before looking at the blower or the lifting motor.
If the vent stops partway up or ignores the switch, we test the switch and the lift next. Several widths share this family, so the data label shows us exactly which vent is on your counter. Some parts are scarce, and we say so up front. A written price arrives before any work, and the workmanship is warranted for 30 days.

How often should I service the filters on a Heritage downdraft?
The metal grease filters are cleaned about every 8 to 10 weeks, and the carbon filter is replaced between 3 and 12 months. Heavy cooking shortens those intervals, and overdue filters are a common reason airflow feels weak.
Why would my HRV46 stop partway up?
We usually find a sticking lift mechanism or a switch that no longer sends a clean signal. We test both and look for grease in the track before telling you which part is needed.
What details help before you arrive?
Note whether the vent stops partway, stays down, or rises but moves little air, and when the filters were last washed. These details tell us whether to begin with the switch, the lift, or the filters.
