How to Fix / Troubleshooting

Safety first: Turn OFF power at the breaker or unplug the range.

Reset:

  • Leave power off for 5 minutes to reset the electronics.
  • Restore power and test the cooktop controls.

Internal inspection (advanced):

  • Remove the rear panel and, if necessary, the cooktop glass to access the control boards.
  • Inspect the ribbon cable from the touch panel to the main PCB and the harness from the PCB to the cooktop module.
  • Reseat all connectors and look for bent pins, corrosion, or burn marks.

Next steps: If reseating connectors does not resolve the issue, either the cooktop module or main PCB is likely defective. Due to the complexity of diagnosis, contact a qualified technician for board-level replacement.
