Induction cooktop does not recognize any pan on one specific zone, but other zones work.

Safety first: Disconnect power before accessing internal components. Induction circuits carry high voltage and current.

Steps:

• Verify cookware: Test multiple known-good induction pans on the affected zone. Confirm they work on other zones.
• Inspect wiring: Remove the cooktop and bottom cover. Check the wiring harness from the affected coil to the power module and any associated sensors. Reseat connectors.
• Test coil continuity: Use a multimeter to check continuity of the coil. An open coil indicates a failed induction coil assembly that must be replaced.
• Replace module or coil: If the coil is good but the zone still does not detect pans, replace the zone's power module or combined coil/module assembly per the service manual.

Note: Mark all connectors before removal to avoid cross-connecting zones.
