Possible Causes

Open or shorted induction coil, Faulty coil temperature sensor, Loose coil harness connection, Failed induction driver circuit on power module

How to Fix / Troubleshooting

Safety first: Turn OFF power at the breaker. Wait 5–10 minutes for capacitors in the induction module to discharge.

Usage checks:

  • Verify you are using induction-compatible cookware (magnetic base). Test with a magnet; it should stick firmly.
  • Ensure the pan fully covers the marked cooking zone.

Internal checks (advanced):

  • Remove the cooktop glass to access the induction coils.
  • Inspect the affected coil for cracks, burnt spots, or detached mounting hardware.
  • Check the wiring harness from the coil to the power module for loose or damaged connectors.
  • With a multimeter (unit unplugged), measure coil resistance and compare to service specs. Replace the coil if open or shorted.

Note: If the coil and wiring are good, the induction power module may be defective and should be replaced by a qualified technician.
