Whirlpool Cooktop: light stays on

Professional Repair Guide

What is this symptom?

If your Whirlpool cooktop's indicator light remains on even when the appliance is turned off, you're facing a common issue. This could be due to a functioning residual heat indicator, a stuck thermal switch, or potentially a faulty infinite switch. Understanding these causes will help you determine the next steps for resolving the problem effectively.

Urgency: Medium

Possible Causes

Residual heat indicator functioning normally

How to Identify: Indicator light remains on only while surface is physically hot; surface feels warm to touch and cools over time.

Part: Hot surface indicator / thermal sensor

Stuck thermal switch (Hot Surface Indicator circuit)

How to Identify: Indicator stays lit even when surface is cool; multimeter test shows continuity on thermal switch at room temperature.

Part: Thermal switch / hot surface limiter

Faulty infinite switch (burner control switch)

How to Identify: Cooktop "On" light stays on regardless of individual burner positions; disconnecting wires to switch stops indicator light.

Part: Infinite switch (behind burner knob)

Control board relay or electronic control failure

How to Identify: All sensors and switches test normal, but indicator still stays on; control responds inconsistently or shows other control errors.

Part: Control board / control electronics

Wiring issue (short circuit, damaged insulation)

How to Identify: Visible damage, burning smell, or arcing; continuity indicates unintended paths powering indicator.

Part: Wiring harness

Preventive Maintenance

  • Regularly inspect cooktop controls and indicator lights: Early detection of switch or sensor malfunctions
    Frequency: Monthly
  • Clean control panel area to prevent spills into switches: False switch contacts and indicator errors
    Frequency: After spills or heavy use
