Wolf Hood Blower Motor
Its job
- Spins the blower wheel that pulls smoke up through the baffle filters and pushes it out past the damper into the duct.
- Runs at the speed the control asks for, and is sped up automatically by the heat sentry when the exhaust gets hot.
- Lives in the hood itself, in the duct run or outside at the roof or wall — Wolf offers internal, in-line and remote blowers.
Signs it is going
- Hums without turning, or turns slowly and weakly however high the control is set.
- Stops mid-cook and starts again once cool — the built-in thermal overload shutting down a motor that is running hot.
- Grinds or whines as its bearings wear; dust from building work drawn into the blower speeds that along.
Our order of work
- Prove the supply and the speed control first, so a good motor is never swapped for a bad switch.
- Check the wheel, the bearings and the mounting, and whether the motor spins freely by hand with the power isolated.
- Quote the motor in writing before ordering it, then fit a factory-approved replacement and run every speed.
Motor, or everything around it?
Plenty of calls that begin with “the motor has gone” end somewhere else: filters loaded with grease, a damper stuck half-shut, a speed control that no longer passes full power. The motor takes the blame because it is the part that hums.
A motor that really has failed usually says so in one of the three ways listed above — and the overload one is the easiest to miss, because the hood looks fine again an hour later.
In-line and remote blowers
When the blower sits in the duct run or out on the roof, the motor is out of sight but not out of reach. We listen at the hood, check what reaches the blower electrically, and only then go to the unit itself. Nothing on this page asks you to go looking for it.
Before anything is ordered
The right replacement depends on the exact hood and blower, so the rating plate comes first — on a current Wolf pro hood it sits inside the hood shell, and the use and care guide shows the spot for other models. Read it to us on the phone and the likely part is pinned down before the visit.
Two-Minute Check
Run it in order. Nothing here needs a panel off, a ladder or a wire touched.
- Check the breaker that feeds the hood and reset it once if it has tripped — if it trips again, leave it off.
- Wash and refit the baffle filters before judging the motor, and never run the blower with them out.
- Try each speed in turn and note which ones start the blower, which only hum and which do nothing at all.
- If it cut out mid-cook, leave it off until the hood is cool, then try once more — a restart means the overload tripped.
