Possible Causes
How to Fix / Troubleshooting
Safety first: Turn OFF power at the breaker and allow the cooktop to cool completely.
Basic checks:
- Verify the hot surface indicator for that burner works; if it never lights, the element may be open.
Internal inspection (advanced):
- Remove the cooktop glass to access the radiant elements.
- Inspect the affected element for visible breaks or burn spots.
- Check wiring connections to the element and control switch/board.
- Test the element for continuity with a multimeter; replace if open.
Note: If the element is good, the burner control (infinite switch or PCB) may be defective and should be replaced by a technician.
