Range Vent Hood Circuit Board & Timer Parts

Range Vent Hood Control Board and Timer Failures

A dead range vent hood usually traces back to the control board or timer assembly. When the buttons don't respond, the display goes blank, or the fan won't turn on at all — the circuit board is the first place to look. Unlike a simple switch failure, a bad control board means your speed controls, timer functions, and safety interlocks stop working. OEM replacement boards come programmed for your exact hood model and restore full functionality.

Control boards for range vent hoods are model-specific, especially on factory-certified brands like. Aftermarket generic boards rarely match the original's feature set or voltage requirements. Enter your model number to find the exact circuit board, timer assembly, or switch parts your hood needs.

• No response to button presses: Control board failure; display may be blank or dim
• Timer doesn't count down: Timer relay or board part failure
• Speed controls stuck on one setting: Board or relay malfunction
• Lights won't turn on (fan runs): Light relay failure within the board
• Fan won't turn on (lights work): Motor relay or fan contactor on board has failed

See Range Vent Hood Parts for motors, blowers, filters, and complete assemblies. Find your model number on the hood's nameplate or inside the ductwork to get the right board fast.

Range Vent Hood Control Board & Timer Questions

What does a range vent hood control board do?

The control board (also called a circuit board, timer board, or ERC — electronic range control) manages every electrical function of your hood: fan speed selection, timer countdown, light operation, and safety interlocks. When it fails, buttons stop responding, the display goes dark, or individual functions like the light or fan may work but not others. A bad board can't be repaired — it must be replaced with an OEM unit programmed for your hood model.

How do I know if my hood's control board is bad versus just a switch?

Test the simplest thing first: unplug the hood for 30 seconds and plug it back in. If the display lights up but buttons don't respond, or if only one function works (like fan but no light), the board is likely failed. If nothing happens at all — no display, no sound, no response — check the breaker and the outlet. A failed switch usually affects only one button; a failed board affects multiple functions or the entire unit.

Can I buy a range vent hood control board?

No — control boards are model-specific. Even within the same brand (, ), different hood models use different boards with different relay configurations, voltage ratings, and connector types. Ordering by your exact model number ensures the new board has the right button layout, timer functionality, and safety interlocks. A mismatched board won't fit or won't power the fan and light correctly.

Where do I find my range vent hood model number?

The model number is on a nameplate typically located inside the hood, under the filter or blower wheel, or on the back panel near the ductwork opening. It may also be on a sticker inside the cabinet above the range. Look for a label that starts with letters (like WPL, FFGC) followed by numbers. Enter this model number into Repair Clinic's lookup tool to find the correct control board, timer relay, and all compatible parts for your hood.

Where to Find Your Range Vent Hood Model Number

Check the underside of your range vent hood, behind the grease filters, or along the side or top of the cabinet for the manufacturer's model label. If you do not see it there, check the owner's manual or installation paperwork, which often lists the full model number. Look for the model number, not just the serial number, and copy it exactly, including letters, numbers, and any dashes. Enter that number in the search bar to filter the catalog to parts that fit your specific range vent hood. Since the model identifies the whole unit, it narrows every related parts category, not only the control parts. You order with confidence knowing the fit is right.
