Why your Greenheck commercial kitchen hood is making loud noise
Catching making loud noise early on a Greenheck commercial kitchen hood is usually straightforward: grinding, buzzing, or rattling — usually a worn fan or drive motor, failing bearings, or a loose part vibrating against the housing. Nine times out of ten it comes down to debris caught in the blower housing.
Most likely causes
- Debris caught in the blower housing
- A loose or unbalanced fan wheel
- A failing blower motor or fan wheel
- Worn motor bearings
Known Greenheck commercial kitchen hood weak points
- grease accumulation in baffle filters, plenum and grease-duct
- upblast exhaust fan belt slippage, bearing wear and motor burnout
- insufficient make-up air causing negative pressure and backdraft
- control/DCKV sensor faults and fan-speed lockout
Quick check — and when it's not DIY
Start here — it costs nothing and rules out the easy cause: run it briefly to hear whether the noise is load-related or constant. Also, confirm the commercial kitchen hood is level and that nothing loose — coins, small items — is rattling inside or underneath it. Once you've ruled that out, a constant grinding or squealing noise usually means a bearing or motor is already failing, and continuing to run it can cause it to seize completely.
