Flat $129 diagnostic, written estimate. Source: https://jaxwolfco.com/repairs/ventilation-hood/ Updated: 2026-08-15 What owners describe: - Hood runs but barely pulls smoke off the cooktop - Blower has become loud or vibrates at high speed - Fan turns on by itself or will not turn off - Halogen or LED lights have stopped working - Controls respond to some buttons and not others - Downdraft rises partway and stops - Rattling from the duct when the blower starts - Grease dripping from the underside of the hood Ventilation is the part of a high-output kitchen that gets specified last and thought about least, and it is the appliance most likely to be genuinely undersized rather than broken. Before we replace a blower we work out whether the hood ever moved enough air for the cooking surface underneath it, because a hood that has always struggled is a different conversation from one that used to work and now does not. ## "It runs but it does not pull" Start with the filters. Baffle filters are dishwasher-safe and most owners run them far less often than they should. A baffle pack loaded with cooled grease loses a large fraction of its open area, and the blower — which is a fixed speed device — simply moves less air through it. If the hood was quiet and strong two years ago and is quiet and weak now, filters are the first and cheapest thing to rule out. Next is the duct. A run that is too long, has too many elbows, or steps down to a smaller diameter somewhere in the attic will throttle any blower. The most common single fault we find is a wall cap whose damper has stuck partly closed, usually with grease or with a wasp nest. That is a five-minute find from outside the house and it is worth doing before anyone opens the hood. Then there is make-up air. A powerful hood in a tight house cannot exhaust what it cannot replace. If your extraction is noticeably better with a window open, the hood is fine and the house is the constraint. That is a real and common finding in newer construction around Bartram Park and the Baymeadows corridor, where envelopes are much tighter than in the older parts of the city. ## Noise and vibration A blower that has become loud has usually become unbalanced. Grease builds up on the wheel unevenly, and beyond a certain deposit the assembly runs out of balance and works its bearings. Cleaning the wheel restores quiet operation more often than replacing the motor does — though once a bearing is audibly dry, cleaning will not save it. Rattle that starts and stops with the blower, but sounds like it comes from the wall or the ceiling, is nearly always the duct or the damper rather than the appliance. ## Downdrafts A downdraft that rises partway and stops is a mechanism problem: the lift screw or the belt drive is binding, usually because something has been spilled into the slot and dried there. Forcing it makes the motor work against the obstruction and can strip the drive. The same is true for a downdraft that rises and immediately retracts — that is the controller seeing an over-current and protecting itself, which is a symptom of drag, not of a bad motor. ## Lights and controls Hood lighting sits in the hottest, greasiest part of the kitchen, and lamp holders corrode. When a single light fails, the socket is as likely as the lamp. When all of them fail together, look at the transformer or driver. Controls on a hood are simple, and simple failures are usually connectors. The loom runs from the control panel through the chimney to the blower, and it gets pulled every time somebody removes the flue cover to clean. ## Salt air, if you are near the water Stainless steel is not stain-proof, and hoods take the worst of it: heat, moisture and, on the east side of the county, salt carried inland on the wind. Rust blooms on a hood surface are almost always contamination sitting on the passive layer rather than the steel itself failing. Wash with warm water and detergent, dry along the grain, and do it more often the closer you are to the Intracoastal. ## Ventilation and the cooking surface If your rangetop burners are healthy and your kitchen still fills with smoke, we look at both appliances together on one visit. The two are a system, and diagnosing either in isolation gives you half an answer. ## What the visit looks like Flat $129 diagnostic, credited toward the repair, written estimate before any part is ordered, genuine OEM parts. Blower assemblies are matched to the hood housing and to the duct diameter it was built for, so we want the model and serial before we quote one. --- Kindling Range Service is an independent appliance repair company.
