Maytag Oven Error Code F-12

The F-12 error code on a Maytag induction range indicates an under-current condition detected in one of the induction cooktop coils. This is classified as a Type 1 failure, meaning only a single burner zone is affected rather than the entire cooktop. The induction system relies on precise current flow through the coil to generate the oscillating magnetic field that heats compatible cookware. When the Induction Power Control module detects that the current through a coil circuit has dropped below the expected threshold, it triggers F-12 to protect the system and alert the user.

The Induction Power Control (IPC) board is the central component involved in this fault. It monitors current through the coil connections labeled T2A-T2B and T3A-T3B, which correspond to specific burner zones on the cooktop. A loose, corroded, or disconnected terminal at these connection points is the most straightforward cause of the under-current reading, which is why the first diagnostic step is to disconnect power and inspect those terminals directly. Beyond connection issues, a damaged coil winding or a failing IPC board can also produce this fault code.

Because induction coils operate at high frequencies and interact directly with the IPC's power electronics, even minor wiring faults at the coil connection points can cause significant current drops. Technicians should check for physical damage to the wiring harness between the IPC and the affected coil, verify that all terminals are fully seated and free of corrosion, and test the coil for continuity before condemning the IPC board itself.
