A blower spins thousands of times a minute, and any imbalance or looseness turns that spin into shaking. The parts that rattle are often small: a filter that sits loose in its track, a baffle knocking on its neighbor, the chimney cover's upper and lower sections touching, a light lens with a broken clip, a damper flap chattering in the duct, a screw that backed out of the canopy. The shaking itself usually starts at the blower: a wheel with a lopsided crust of grease, a bent or missing blade, a motor whose rubber mounts hardened and cracked. Shaking matters beyond the noise because it slowly works everything loose, including the screws and brackets that hold the hood to the wall, the ceiling or the cabinet. That is why a hood that shakes more each month deserves a look before it starts pulling away, and why a hood that has begun to move should be treated as urgent on its own page. Tightening the upper chimney cover or reaching into the blower housing from a ladder is not something to try; the parts are reached with the power off, from the right position. The 6 causes, cheapest first Answer these first 01 Does the rattle start at once with the fan, or only on the top speed? 02 Does the rattle go away once a loose filter or light lens is pressed back into place with the hood off? 03 Does the whole canopy or the cabinet above shake, or only one part buzz? 04 Is there a ticking in the duct above, like a flap chattering? 05 Has the hood moved at all, with a gap at the wall, the ceiling or the cabinet? ## Check these before you book. Range hood rattling: 5 checks, and none of them costs anything. 01 With the hood off, press each filter firmly into its track until it seats flat and latches. 02 Run the fan on each speed and note where the rattle comes from and on which setting. 03 Look for a gap between the hood and the wall, the ceiling or the cabinet above; if there is one, stop cooking under it and see the page on a hood pulling away. ### Also worth checking - Do not climb up to the chimney cover or open the blower housing to find the sound. - Book a visit with the model number from behind the filters and a short phone clip of the rattle. ### How soon does it need a visit? A rattle on its own can wait for a visit, but switch to a lower speed that stays quiet in the meantime. Any sign the hood itself is moving on the wall, the ceiling or the cabinet changes that: no cooking under it and nobody under it until it is secured. ## The causes, cheapest first. 6 things range hood rattles or shakes while it runs turns out to be, from loose or poorly seated filters to worn motor mounts. [The cost guide](https://rangehooderepair.center/cost/) 1. 01 no repair ### Loose or poorly seated filters Baffle and mesh filters that sit loose in their tracks buzz against each other and the canopy. Seating each one firmly, or a new latch, stops it. [Fixed by range hood filter and baffle service](https://rangehooderepair.center/services/range-hood-filter-and-baffle-service/) 2. 02 low ### Chimney cover sections touching The upper and lower sections of a telescoping chimney cover can touch or sit loose on their bracket, and the blower's vibration turns that into a buzz. They are reset and fixed apart on a visit.

[Fixed by range hood damper and duct repair](https://rangehooderepair.center/services/range-hood-damper-and-duct-repair/) 4. 04 low to moderate ### Mounting screws working loose Screws into the wall, the cabinet floor or the ceiling frame can back out under years of vibration. They are refixed, and if the hood has started to move, the mounting is rebuilt. [Book a diagnostic visit](https://rangehooderepair.center/services/diagnostic-visit/) 5. 05 moderate ### A blower wheel out of balance Grease caked unevenly on the wheel, or a bent blade, makes it wobble at speed. Cleaning or a new wheel usually brings the hood back to a steady hum. [Fixed by range hood noise and vibration repair](https://rangehooderepair.center/services/range-hood-noise-and-vibration-repair/) 6. 06 moderate ### Worn motor mounts The rubber isolators that cushion the motor harden and crack with heat. Without them, the motor's vibration goes straight into the canopy and the cabinet.

Why? Clean filters often go back in more squarely, and a filter that was loose in its track was the source. If it returns, check the latches. ### Is some vibration normal on the top speed? A slight hum through the canopy is normal on high. Visible shaking, a cabinet door that buzzes or a rattle that gets worse over time is not. ### Can vibration loosen the whole hood? Over years, yes. A blower out of balance works the mounting screws loose, which is why a hood that shakes more each season deserves a check before it moves. ### Why does the rattle come from the ceiling, not the hood? The duct or the damper above the ceiling can chatter in the airflow, and a duct strapped loosely to a joist can drum. Those are traced from below or from the attic by a technician. --- **[Read on the site: Range Hood Rattles or Shakes While It Runs: Causes and Fixes](https://rangehooderepair.center/problems/range-hood-rattling-or-vibrating/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
