Symptom
DCS hood not clearing smoke
DCS range hood not clearing the kitchen. Before anything is opened there is a question that resolves a surprising share of these calls: where is the air actually going. Air that leaves the building behaves nothing like air that is filtered and handed back, and a large share of these calls turn out to be the second kind of hood doing precisely what it was fitted to do. On a hood that genuinely vents outside, the suspects are filters nobody has washed, ducting flattened by whoever worked in the ceiling, a wall cap whose flap has stopped lifting, or a wheel turning at a fraction of the speed it should.

Three ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The filters are loaded
A griddle and burners of this output render more fat than a domestic hob ever will, and once the baffles are saturated they choke the airflow and hold fuel directly above open flame. Nothing else on this page costs so little to correct.

The duct is blocked or damaged
Flexible ducting squashed flat during someone else's work, a seam that let go years ago and now vents into a void, a cap corroded shut. No motor ever made overcomes any of them.

The blower has lost its speed
Fat caked on the wheel, a bearing on its way out, or a speed control that has settled on its lowest step. The hood makes the right noise and shifts almost nothing.

01
Is it ducted or recirculating?
Look for a duct leaving the top or the back. Nothing leaving means nothing leaves, and repairs will not alter that.
-
02
Can you see light through the filters?
Toward daylight. If they are opaque, run them through a dishwasher and retest before anybody is called out — free, and often the end of it.
-
03
Does the exterior flap open with the fan on?
Thirty seconds outdoors. A flap that has been painted over or colonized halts the whole system and is completely hidden from indoors.

About DCS hood not clearing smoke
What to do in the next ten minutes
Pull the baffles and hold one toward a window. Light through it means air through it; no light means no air, and they will go in a dishwasher. With them out, run the fan and put a palm up inside the canopy to feel what suction is actually there. Last, walk outside while it runs and watch the exterior flap — it should be standing open.
A great many of these are working correctly
Filtering hoods take grease and odor out of what passes through them and return the rest to the kitchen. Heat and steam stay where they were. That is the specification, not a defect, and we would far rather settle it in a phone call than charge somebody to hear it in their own kitchen. If the equipment is genuinely mismatched to how the family cooks, the honest conversation is about ductwork, not about parts.
Most of the machine is hidden in the structure
Once air leaves the canopy it travels through somebody's construction, and that is where the majority of genuine failures live. We have found runs flattened between joists, sections lying disconnected in a soffit, and exterior terminations rusted solid. A perfectly healthy motor at one end of that proves nothing at all, which is why the route gets traced rather than the fan tested.

Before you book
Questions about DCS hood not clearing smoke
How often should the filters be washed?
Far more frequently than they are. With burners of this output and a griddle in the mix, once a month is a reasonable rhythm, and a dishwasher does the work. What convinces people is not the advice but the airflow the first time they do it.
Could a filtering hood be re-plumbed to vent outside?
Occasionally, and the answer is written in the structure overhead. A straightforward path to an outside wall or up through a roof makes it worth quoting; a canopy buried beneath two storeys of house generally does not. We can tell you which you have in one visit.
