Hood Control Board
| What it is | The circuit board that reads the buttons and passes power out to the blower and the lamps. |
|---|---|
| Where it sits | In the canopy behind the controls, on standoffs |
| How it fails | No response to any button, or lights and blower stuck together |
| Checked with | Supply voltage in, switched voltage out, one circuit at a time |
| Price | Quoted after the $89 visit |
The board behind the controls
It is the one component in a hood that touches everything else. Lighting, blower speed, the automatic response to heat, the signal sent to a blower that is not in the kitchen: all of it departs from the same board. That is why a single board fault can present as four unrelated complaints, and why it is the last conclusion reached rather than the first one guessed.
Dead to every button
A hood doing nothing at all is checked at the breaker first, because a tripped circuit and a dead board are indistinguishable from below. Past that, the two pictures are a board with no supply arriving and a board whose supply no longer switches. Lamps lighting while the blower ignores every press points the other way: the board is alive, and one output is not.
Voltage in, voltage out, one circuit at a time
The board is read, not swapped. Supply at its input terminals first, then each output taken in turn while the matching button is held. An output that stays dead behind a good command has condemned itself; an output that comes up correctly moves the fault further along, to the motor, the lamps or the wiring between. No band is published for a hood board here, for the same reason none is published for a hood blower: the bands on this site were written for cooking appliances, and a figure borrowed from one of them would be a guess wearing a number.
What putting it right costs
This one has no published band. Wolf Repair Los Angeles puts a figure on it after the diagnosis, as one number covering the part and the labour, and nothing is ordered until you have agreed it — (310) 626-4008.
A flat $89 buys the call-out and a full diagnosis, and that $89 is deducted from the repair once you have approved it.
Follow-ups
Is a hood control board worth replacing, or is the hood finished?
The canopy, the ducting and the blower are the costly half of any hood, and a board fault leaves all three untouched. Where a board is still made for the model, replacing it is the cheaper road by a wide margin. Availability gets checked and the figure quoted before you are asked to decide.
The lights and the blower stopped on the same evening. Is that the board?
Frequently it is, because both leave that one board — but a supply problem ahead of it looks the same from underneath. Wolf Repair Los Angeles reads the incoming side first, since ruling out a shared failure upstream costs nothing and saves a part. The number is (310) 626-4008.
