Possible Causes

Burned-out radiant element, Loose or burned wire at element terminal, Failed infinite switch or relay

How to Fix / Troubleshooting

Safety first: Disconnect power at the breaker. Radiant elements can remain hot even when dark; allow full cool-down.

Steps:

  • Access element: Remove the cooktop from the counter and lift the glass top per the service instructions to expose the radiant elements.
  • Inspect wiring: Check for burned or loose wires at the element terminals. Repair or replace any damaged wiring with high-temperature-rated wire.
  • Continuity test: Disconnect at least one lead from the suspect element and test for continuity. An open circuit indicates a failed element.
  • Replace element: Install the correct OEM radiant element. Ensure all mounting clips and temperature limiters are properly positioned.
  • Control check: If the element tests good, test the infinite switch or relay output to the element. Replace the switch or control board if it does not supply power when commanded.

Note: Handle the glass top carefully to avoid cracking.
