# Your Dacor Hood Switching Itself On Is Probably Correct

The first time it happens in an empty kitchen it is unnerving. It is also, nine times out of ten, the hood being sensible.

## Dacor hood turns on by itself: what the feature is for

A hood sits directly above the hottest thing in the kitchen, with cabinetry around it and a duct above. Left unventilated through a long high-heat session, that space gets hot enough to matter — not dramatically, but enough to age the joinery and the appliance's own wiring.

Starting the fan automatically is cheap insurance, which is why the behavior appears in the manual rather than in a code table.

## When it is working

A long roast. A hard sear on a professional rangetop with six burners. A pan boiled dry. In each case heat under the canopy crosses the threshold, the hood starts, and it stops again once the temperature falls.

If the range was in use and the hood stopped on its own afterwards, nothing needs doing.

## When it is a problem

With a cold range and nothing cooking. That points at the sensor, and in a working kitchen the usual reason is grease: a fouled sensor reads warmer than the air around it, crosses the threshold earlier and earlier, and eventually triggers with the hob switched off.

A proper clean of the canopy and the sensor often ends it outright, which makes this one of the cheaper problems on the list.

## The other problem: it will not stop

A hood that refuses the off command is not an overheat response. That is the control panel — and on the glass touch panels the keys nearest the heat fail first — or a remote or wall control sending on its own.

Both are ordinary repairs, and both are worth distinguishing from the protection behavior before anybody is called.

## Why there is no code for any of this

The control panel on these hoods is a set of buttons with no display, so there is nothing to show a code on. The manufacturer's own manual troubleshoots the hood as problem, cause and solution in plain English — including "Fan comes on by itself", which is listed as normal behavior.

Several appliance sites publish code tables for Dacor hoods anyway. They are contradicted by the document that came with the appliance, and this site does not repeat them.

## The clean that usually ends it

Grease on the sensor is the ordinary explanation for a hood that has recently developed this habit, and it responds to a proper clean rather than a part. That means the canopy interior, the sensor itself and the area around it — not just the filters, which is as far as most cleaning gets.

It is worth combining with a filter and blower service, because the same grease that fooled the sensor has been collecting on the wheel. A hood that starts by itself and is also louder than it used to be is telling you about one problem twice.
