DHI421
Dacor Discovery DHI421 Hood Repair
Most common issues on this model
- Auto-off timer that shuts the blower early or not at all
- Filter-clean reminder behavior
- Metal grease filters and the carbon filter option
- Chimney and ceiling mount
The DHI421 is a 42-inch island-mount range hood from Dacor’s Discovery line, and the width comes straight from the model number. It is electric and has metal grease filters. Island mounting means the hood hangs from the ceiling over a cooktop in the middle of the room.
Two timers make this hood different. The blower turns itself off after 4 hours, and the hood reminds you to clean the filters after 30 hours of use. When owners say the hood stopped on its own, we ask how long it had been running. A reminder that never clears or never comes is a control issue. We also check the filters, which may be used with a carbon filter in this hood family.
We confirm the model from the data label before ordering parts. Pricing is given in writing first, and we back repairs with a 30-day warranty.

Why did my hood shut off while I was cooking?
This hood turns the blower off by itself after 4 hours. If it stops sooner, the timer or control may be failing, and we test them.
How does the filter reminder work?
It reminds you to clean the filters after 30 hours of use. If it stays on after cleaning, the reminder may need resetting, or the control may not be clearing it.
Do I need a carbon filter?
The Discovery family uses metal grease filters, and a carbon filter is also used with it. Which you have depends on how the hood is vented, so we check what is installed.
