Whirlpool Cooktop Error Code F-40

F-40 indicates that the Induction Power System has detected a stuck or non-responsive cooling fan. Whirlpool induction cooktops use internal fans to cool the power electronics, and the cooktop will shut down if the fan on either the left or right side is not spinning. The side of the display showing the error indicates which fan is affected.

No. The cooktop displays F-40 and disables operation specifically to prevent the power electronics from overheating without adequate cooling. Attempting to bypass or ignore this fault could cause internal component damage or create a fire hazard. Do not use the cooktop until the fan issue is resolved.

Repair costs vary depending on the root cause. A replacement cooling fan motor typically runs in the range of $30 to $80 for parts, while a new IPS control board can cost considerably more. Adding professional labor, total repair costs can range from roughly $100 to $350 or more depending on which components need to be replaced and local service rates.

Some causes of F-40 can be addressed by a knowledgeable DIYer. After unplugging the cooktop, you can inspect the affected fan for obstructions and check that the wiring harness is securely connected. However, if the fan motor itself has failed or the control board needs replacement, those repairs require sourcing the correct parts and comfort working with appliance electronics.

A power reset by unplugging the unit or tripping the circuit breaker for a few minutes may temporarily clear the error code, but the fault will return if the underlying fan problem is not repaired. The F-40 code is triggered by a real hardware condition, so a reset alone is not a fix.
