Whirlpool Cooktop: light stays on
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.
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
