Induction cooktop displays F61, one or more zones inoperative.

Safety first: Disconnect power. Induction circuits carry dangerous voltages.

• Check cookware and usage: Ensure you are using induction-compatible cookware and not running empty pans at high power, which can stress the module.
• Inspect wiring: Access the underside of the cooktop and inspect wiring from the affected zone coil to the power module. Look for loose connectors or burnt terminals.
• Test coil continuity: With power off, measure resistance of the induction coil. An open reading indicates a failed coil.
• Replace module: If the coil and wiring are good, the induction power module for that zone is likely defective and should be replaced.
