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 row starts at $165 and reaches a long way up. ### The idea this maker invented JennAir built the first self-ventilating cooktop in 1961 and the first downdraft range in 1965, and there are still downdraft cooktops, a downdraft range and downdraft ventilation units in the current line. There is a very large installed base in South Florida from every decade in between, including the cartridge cooktops where a grill or griddle module lifts out. Those are usually still repairable; electrical and mechanical parts are commonly available and some cosmetic parts are not, and availability is confirmed before an order rather than after. ### What this page absorbs The vent side of an over-the-range microwave, from $135 — the cheapest visit on this site. On those units a dead microwave is a dead hood, and the reverse is not true: a fan that has stopped while the microwave heats perfectly is a hood repair on its own. What moves this figure Researched market range: blower motor $250–$550; capacitor $120–$250; filter service at the low end Filter, damper and duct come before the blower — three of five are outside the machine Absorbs the microwave-hood vent work, from $135 Where the blower actually is In the unit, in the cabinet below, or remote at the end of the duct run — sometimes in a crawl space or on an exterior wall. It is not visible from the kitchen and it is what moves this figure most. Whether it is the appliance at all A saturated grease filter, a stuck damper or a crushed duct are the first three suspects and the cheapest. A real share of these calls end at a filter. Retractable or not A downdraft that rises out of the counter adds a motor, a drive and position switches inside the countertop, and reaching that mechanism is the top of this band. Ducted or recirculating On a microwave-hood, the question almost nobody can answer. A recirculating unit with a saturated charcoal filter moves air and removes nothing, which is exactly the complaint people call about.

The blower is turning and the air is not going anywhere. Filter, damper, duct — in that order, and three of the five causes are outside the machine. We check the path before quoting the appliance. ### How much is a downdraft blower? It depends more on where it is than on what it is. In the unit is the middle of this band; remote at the end of a duct run in a crawl space is the top. Finding it is part of the diagnostic. ### My downdraft will not rise. That is the lift mechanism — a motor, a drive and position switches inside the counter — and it is the top of this band because reaching it is the job. It usually gives warning first by getting slower or noisier, which is a good moment to call. ### Mine is from the nineties. Worth repairing? Usually, and worth asking rather than assuming. Electrical and mechanical parts for these are commonly available; some cartridges, trim and control panels are not. We tell you which side of that line you are on before anything is ordered. --- **[Read full article: Downdraft and venting repair cost](https://jennairmiami.support/repair-cost/downdraft-vent-and-lift-repair/)**
