In a kitchen that cooks properly they want washing monthly, and a saturated filter moves air and removes nothing. Then hold a sheet of paper at the intake with the blower running: if it does not hold, the air is not going anywhere and the problem is downstream of the filter. ### Five things, and three are not the machine A downdraft has to move air sideways and down and then along a duct that runs under a floor or through the back of a cabinet. The filter, the damper, the duct, the blower and the control can each stop it, in roughly that order of likelihood — and the first three are cheap or free. That is why this page starts at a filter and why the visit does too. ### The idea this maker invented JennAir built the first self-ventilating cooktop in 1961 and the first downdraft range in 1965: ventilation pulled down through the cooking surface rather than up into a hood, which is what made an island cooktop in an open-plan kitchen possible. There are still downdraft cooktops, a downdraft range and downdraft ventilation units in the current line, and there is a very large installed base in South Florida from every decade in between. ### The retractable ones give warning A downdraft that rises out of the counter adds a motor, a drive and position switches inside the countertop. Because it is mechanical, it usually gets slower, noisier or stops short before it stops altogether — which is a good moment to call, because reaching that mechanism is the expensive half of the job and it does not get cheaper by waiting. A saturated grease filter The free half of this, and the answer more often than any part. A damper that has stuck It has to open when the blower starts. After a few humid years it sometimes does not. The duct run Under a floor or through the back of a cabinet — crushed, disconnected, or terminating somewhere nobody has looked at since the kitchen was built. The blower, wherever it lives In the unit, in the cabinet, or remote at the end of the run. A remote blower that has stopped produces a downdraft that hums and does nothing. The lift mechanism On a retractable unit: a motor, a drive and position switches inside the countertop. Mechanical before it is electronic. Wash the filter It lifts out by hand, goes through a dishwasher or a sink of hot water, and must be dry before it goes back. The paper test at the intake With the blower on. If paper does not hold against it, the air is not moving through and the filter is not the answer. Listen for where the noise is A blower in the unit sounds different from one at the end of a duct. It is genuinely useful for finding it. Watch the lift, if you have one Slower, noisier or stopping short is a warning rather than a failure, and it is a good moment to call. Then book it Model number, whether the blower runs, and whether you know where it is. That last one is a real question and most people do not. And most of it is not the appliance What it usually means Running but no longer clearing the cooktop Not rising out of the counter Noisier than it used to be The fastest diagnosis is the code Take the grease filter out and look at it — really look, not glance.

Then the blower is turning and the air is not going anywhere. In order: the grease filter, the damper that has to open when the blower starts, and the duct run itself. We check the path before quoting the appliance, because three of the five causes are not in it. ### Where is my blower? A real question, and often not obvious. It may be in the downdraft unit, in the cabinet below, or remote — at the end of the duct run, sometimes in a crawl space or on an exterior wall. Finding it is part of the visit and it is what moves the figure. ### How often should the filter be washed? Monthly is not excessive for a kitchen in daily use, and it is the single most effective thing an owner can do for a downdraft. It lifts out by hand and it must go back dry. ### Mine is from the nineties. Still worth repairing? Usually, and it is worth asking rather than assuming. The electrical and mechanical parts for these are commonly available; what is scarce is cosmetic and model-specific — some cartridges, trim and control panels. We tell you which side of that line your repair sits on before anything is ordered, and we say plainly when a machine is not worth the part. --- **[Read full article: The downdraft has stopped pulling](https://jennairmiami.support/symptoms/downdraft-not-pulling-air/)**
