Maytag Oven Error Code F-40

F-40 indicates a failure in the Induction Power System (IPS), which controls the induction cooktop burners. The fault can be Type 1 or Type 2, pointing to different conditions within the induction power circuitry. It involves the Induction Power Control board and its communication with the User Interface board. The cooktop burners will typically be non-functional while this code is active.

Unplugging the oven or disconnecting it from the circuit breaker for several minutes can clear the error if it was triggered by a transient power event. However, if there is an underlying hardware fault, such as a damaged cable or a failed IPC board, the code will return after power is restored. A reset is a useful first step but is not a permanent fix if a component has actually failed.

Repair costs depend on which component is at fault. If the issue is simply a loose or damaged cable, cost may be limited to a service call fee, typically in the range of $75 to $150. If the Induction Power Control board requires replacement, parts alone can range from $150 to $400 or more, with total repair costs including labor potentially reaching $250 to $600 depending on your area and service provider.

Some causes of F-40 are DIY-accessible, such as reseating a loose cable between the User Interface and the Induction Power Control board. Start by unplugging the range, then inspect that cable for damage and ensure it is firmly connected at both ends. If the cable is intact and the code returns after restoring power, the IPC or UI board likely needs replacement, which involves working near high-voltage components and is better suited to a qualified technician.

You should not attempt to use the induction cooktop while the F-40 code is active, as the Induction Power System has detected a fault condition. Continuing to operate the range with a known IPS fault could pose a risk of electrical damage to connected components. The oven baking and broiling functions may still operate depending on the specific fault, but the cooktop should be considered out of service until the error is resolved.
