The electric cooktop surface hot indicator light stays on even when all elements are cool.

Safety first: Disconnect power before accessing the cooktop's internal components.

Steps:

• Allow full cool-down: Ensure the cooktop has been off for several hours and has reached room temperature.
• Identify indicator circuit: Remove the glass top to access the elements. Locate the surface hot switch or sensor associated with the indicator light.
• Test switch: Using a multimeter, test the surface hot switch for continuity at room temperature. It should be open. If it remains closed, replace the switch or the element assembly if it is integrated.
• Inspect wiring: Check for shorts between the indicator circuit and line voltage. Repair any damaged insulation.

Note: Some models use electronic sensing; if all sensors test correctly, the main control may be misreading and require replacement.
