Wolf Hood Speed Control and Control Board
Its job
- Sets the blower speed and switches the lights between high and low, from controls recessed under the front edge of a Wolf pro hood.
- Hands over to the heat sentry when the exhaust runs hot — the blower starts or goes to high, then drops back once it cools.
- On a downdraft, splits the job in two: a remote-mounted control module sends commands by cable to the main board in the unit.
Signs it is going
- Goes dead after a power cut or a rough restoration, with the breaker fine and nothing answering.
- Sticks on one speed, or will not reach off, even after the cooktop below has gone cold.
- Takes on moisture from cleaner sprayed straight at it; Wolf says to spray the cloth and never soak the controls.
- Gets run through an extra wall-mounted speed control, which Wolf says its pro hoods must never be paired with.
Our order of work
- Prove the supply first — breaker, connection and what actually reaches the hood — before any control is blamed.
- Rule out the heat sentry, the bulbs and the knob itself, then test the speed control and the electronics behind it.
- On a downdraft, check the cable between the control module and the unit before condemning either end.
- Put the price in writing from the band on this page before ordering, and fit factory-approved parts only.
The board, or what the board is obeying?
A hood that starts unasked is often the heat sentry at work, and one that will not stop may simply still be hot.
Why a Wolf hood won’t turn off sorts those out before anyone opens the hood.
That is why the board comes last in our order. It is the costliest guess, so supply, settings and the simpler parts around it are cleared first.
After a windstorm
Out here, power coming back unevenly after a storm on the overhead lines is a common trigger.
When the feeder goes down explains what a restoration does to electronics, and the breaker habit that spares most of them.
How it is priced
The control board is the one hood part with a set band in our pricing, shown on this page. A wiring or supply fault found instead is quoted after the diagnosis.
Two-Minute Check
Run it in order. Nothing here needs a panel off, a ladder or a wire touched.
- If nothing responds, find the hood's breaker and reset it once; if it trips again, leave it off.
- After an outage, leave the hood off at its breaker until the supply has stayed steady, then switch back on and try the controls.
- If the blower started by itself, turn every burner off and give it time — the heat sentry lets go as the exhaust cools.
- Clean the panel by spraying a cloth rather than the controls, and leave the hood off for a while if anything got wet.
