Range Hood Repair

Wall, island, and insert range hood repair. Motor replacement, fan balancing, and LED lighting service.

Line illustration of a range hood

Wall, island, under-cabinet, and insert range hoods all share the same basic components: a motor, fan blade, light source, and a damper. Most failures are mechanical — a seized motor, a broken damper, a failed LED panel — and most are same-visit fixes. Ducted hoods sometimes need a check on the duct run if airflow has weakened gradually.

01 · How it works

How a range hood works

A range hood pulls air from above the stovetop, filters out grease through removable filters, and either vents the air outside (ducted) or recirculates it back into the kitchen via charcoal filters (ductless). A motorized damper closes when the hood is off to prevent backflow.

02 · Common problems

What we typically fix

  1. 01

    Fan won't turn on

    Could be a failed motor (most common in older hoods), a failed switch or control board, or a tripped breaker. We test each in sequence. Switch failures are the cheapest fix; motor replacements are routine but more involved.

  2. 02

    Lights out

    Range hood lights vary by model — incandescent, halogen, or LED. LEDs are integrated into the unit and don't replace as a bulb; the whole LED panel needs swapping. Halogen and incandescent bulbs are user-replaceable but the bulb often isn't the failure — it's the wiring connector or switch.

  3. 03

    Loud rattling

    Usually the fan blade has come loose on its shaft, the damper is flapping, or there's debris caught in the blower. Less commonly the motor bearings are wearing out. Diagnosis: turn off, look in with a flashlight, check what moves freely.

  4. 04

    Weak airflow

    Three common causes: grease-clogged filters (cleaning often fixes), a partially failed motor (running slower), or a duct restriction somewhere in the run. Cleaning filters first; if no change, motor or duct issue.

  5. 05

    Touch controls unresponsive

    Modern hoods use touch panels that can fail from steam exposure or wear. Sometimes a clean fixes it; sometimes the panel itself needs replacing.

  6. 06

    Damper or duct issues

    The damper is the flap that opens when the fan runs and closes when off. When it sticks closed, airflow drops dramatically. When it sticks open, you get drafts from outside when the hood is off. Both are routine fixes.

03 · Types

Types of range hoods we service

Different builds fail in different ways. Here's what we see most often across each type.

Under-cabinet

Mounted under an upper cabinet, above the stovetop. The most common configuration. Easiest to service since the hood is already mounted within reach.

Wall-mount (chimney)

Mounted directly to a wall above the stovetop with a visible chimney extending up to the ceiling. Looks more dramatic; common in modern kitchens. Service involves working at height.

Island

Mounted from the ceiling over an island stovetop. The duct runs up through the ceiling. Hardest to service — usually requires ladders and sometimes pulling the hood down for major work.

Insert / liner

The mechanical part of a hood installed inside a decorative custom hood enclosure (the wood or metal cabinet you see). Common in custom kitchens. Service requires removing the inner liner from the enclosure carefully.

Downdraft

Pop-up hood that rises from behind or beside the stovetop. Less common, more complex mechanism. Service involves both the airflow components and the lift mechanism.

04 · Warning signs

Signs your range hood needs repair

  • Smoke not clearing as fast as it used to
  • Burning smell from the motor
  • Fan speed not changing when you change the setting
  • Lights flickering or one element out
  • Cold air blowing in when the fan is off
05 · DIY

Try these before booking

Quick checks that resolve a meaningful share of range hood calls without a tech visit.

  1. 01

    Clean the grease filters

    Most filters are aluminium mesh and dishwasher-safe — pull them out, run a dishwasher cycle on hot. For heavily-clogged filters, soak in hot water with degreaser. Clean filters do more for airflow than any service we can perform.

  2. 02

    Check the charcoal filter (ductless only)

    If your hood is ductless, it has a charcoal filter that needs replacement every 6–12 months depending on use. They don't clean — they get replaced.

  3. 03

    Inspect the damper (where accessible)

    If you can see the damper from outside (some installations have it visible behind a louvered grille), check that it opens when the fan runs and closes when off.

  4. 04

    Check the breaker

    If everything's out (fan, lights), it's likely a tripped breaker. Range hoods are usually on a kitchen circuit that also runs other appliances.

06 · Parts

Parts we can replace

Parts we commonly replace during a range hood repair.

  • Blower motor

07 · Prep

Before our visit

What to do

  • Clean grease filters before our visit
  • Note whether the hood is ducted (vents outside) or ductless (recirculating)
  • Take a photo of any error code or behaviour the hood is showing
  • Have the model number ready (inside the hood near the filters)

Finding the model number

Model number is typically inside the hood — remove the grease filters and look at the back wall or the underside. A photo works.

10 · FAQ

Common questions

Specific to range hood repair.

How often should I clean the grease filters?
Every 1–2 months for daily-use kitchens; monthly if you cook with high-heat or oil frequently. Dishwasher-safe metal filters are easiest. Charcoal filters in ductless hoods don't clean — they replace every 6–12 months.
Can I convert my ductless hood to ducted?
Sometimes, if there's a path to vent through an exterior wall or ceiling. The work involves cutting a duct path, installing a wall vent, and possibly upgrading the hood (some ductless hoods don't have enough static pressure for a real duct run). We can scope the project.
Why does my hood need 'makeup air'?
Powerful hoods can pull more air out of the kitchen than the room can replace, creating negative pressure. In well-sealed homes this can cause backdrafting from gas appliances (water heater, furnace) — pulling combustion gases into the house. Modern building code may require a makeup-air system for high-CFM hoods. We can discuss your specific situation.
Why does cold air blow in when the hood is off?
Damper is stuck open or missing. The damper is a flap that closes when the fan stops. If you feel cold air coming through the hood, the damper has failed.
How long should a range hood last?
10–15 years typical. Motors are the most common life-ending failure; everything else (lights, switches, damper) is routine repair territory.
Do you service Wolf and other premium hoods?
Yes — the full premium lineup. Premium hood parts can be specialty-order; we'll quote in writing before any work.
What CFM should my hood be?
Rule of thumb: 100 CFM per linear foot of cooking surface. A 36-inch range needs at least 300 CFM; pro-style ranges often need 600+. Note: higher CFM may require makeup-air systems per building code.
Why is my hood louder on high than it used to be?
Most often grease-clogged filters making the motor work harder. Less commonly, motor bearings wearing out. Clean filters first.
11 · Reference

Worth knowing

How long range hoods last

10–15 years for mainstream hoods; premium hoods (Wolf, Best, Vent-A-Hood) often last 18+ years. Motors are the most common life-ending failure; LED panels, switches, and dampers are routine repair items.
