What we do
Ten repairs we take on. Every range hood repair we offer has its own page: the part the technician actually replaces, how the job compares with its neighbors on the list, and when an aging hood is no longer worth the part.

In the order it gets done: the cheapest cause first, and the expensive answer at the bottom where it usually belongs.
A visit that runs the hood through every speed and light, tests the draw at the filters and follows the air outside until one part is named.
Testing and renewing the fan that moves a hood's air, in the canopy, the duct or on the roof: its capacitor, bearings, wheel or the motor itself.
Repairing the part the cook touches: rocker switches, push keys or a glass touch strip, and the harness that carries their signal to the blower.
Testing and replacing the board behind a keypad or touch strip: the relays for each speed and the lights, the timers and the power supply.
Bringing back the lamps over the burners: halogen and LED lamps, their sockets and covers, and the transformer or driver that powers them.
Cleaning or replacing what catches grease and odor: mesh and baffle filters, charcoal pads on recirculating hoods, and the grease channel.
Getting the air out of the house: the backdraft damper, the duct and its joints, the wall or roof cap, and make-up air in a tight house.
Finding what makes a hood roar, rattle or shake, from a grease-heavy wheel or loose screws to a flapping damper, and quieting it at the source.
Repairing the pop-up vent that rises behind the burners: its lift motor and gears, the limit switches, the blower below and its controls.
Testing the sensor that starts the fan by itself when the burners get hot, so the hood starts when it should and stops when the heat is gone.
Before you bookBands rather than prices, because nobody can quote a figure before the range hood has been looked at — and the diagnostic visit that decides it, set against the repair.
10 repairsCheapest firstDiagnostic visit Read the cost guideSet the repair against what a new range hood would really take to put up, not just its price on a shelf. A chimney hood needs its brackets, duct collar and tile cut to line up again; an island model comes down from the ceiling frame with two people; an insert has to fit the opening a cabinetmaker built around it. Filters, lamps, switches, dampers, capacitors and heat sensors are small next to that, and even a blower or a board is usually the better choice on those three. A basic recirculating under-cabinet hood is the exception: it is quick to swap, so on an older one with a failed motor the technician shows you both numbers side by side.
| Repair | Relative cost | Notes |
|---|---|---|
| Blower motor, run capacitor, bearings or blower wheel | moderate to highest | A capacitor or a degreased wheel sits near the bottom of this band. A complete motor, a twin-blower assembly or a fan that lives in the attic or on the roof climbs to the top, with the reach adding labor of its own. |
| Rocker or slide switch, key panel, touch strip or wall keypad | low to moderate | A mechanical switch block on a basic hood is a small part. A glass touch strip, a membrane panel for a pro-style canopy or a remote keypad with its cable run through the cabinet moves one step up. |
| Control board with its relays and power supply | moderate | The board is the dearest electronic part in most hoods, and one for an imported or premium liner can take time to arrive. Clearing the grease or heat that cooked the old one is part of the same job. |
| Lamps, sockets, lens covers or the LED driver | low | Lamps and lenses are inexpensive. A scorched socket set, a low-voltage transformer or an LED driver hidden above the filters costs more, mostly in the time it takes to reach and test them. |
| Mesh or baffle filters, charcoal pads and the grease channel | lowest | Cleaning and refitting the filters with a new set of charcoal pads is the smallest job on this page. Replacement baffles for a wide pro-style canopy, or grease that has already reached the hood body, add to it. |
| Backdraft damper, duct joints or the outside cap flap | low to moderate | Freeing or replacing a damper at the top of the canopy is a small part and a short visit. Resealing joints above a ceiling, replacing a jammed wall or roof cap, or rerouting a choked run is quoted on its own once it has been seen. |
| Rattles, hum and vibration: wheel balance, mounts, gaskets and screws | low to moderate | Tightening loose panels, reseating filters and adding gaskets costs little beyond the visit. A new motor mount, a replacement wheel or bearings moves it up, and a mounting that has worked loose from the wall or ceiling is priced on sight. |
| Downdraft lift motor, drive gears, limit switches or its blower | moderate | A limit switch or a cleaned track is modest. A lift motor, a drive screw assembly or the blower under the counter costs more, and the cabinet below has to be emptied to reach them. |
| Heat sensor or thermostat disc and its lead | low | The sensor is a small part fitted from the underside of the canopy. When the board that reads it has also failed, the job joins the control board row instead. |
Most people arrive knowing the symptom, not the repair. These are the jobs each one usually turns out to be, cheapest first — and every one of them starts with the range hood diagnostic visit.
