Common Causes of Persistent Cooktop Indicator Lights

If your cooktop indicator lights remain on even after turning off the burners, don't panic. Here are the most common causes and solutions for this issue.

1. Residual Heat Indication

Most modern cooktops have indicator lights that stay on intentionally to warn about hot surfaces. These typically turn off automatically once the surface cools down (usually 20-30 minutes).

How to verify: Simply wait for 30-45 minutes and check if the lights turn off naturally. If they do, this is a safety feature, not a malfunction.

2. Control Panel Malfunction

Sometimes the control panel can get stuck or malfunction due to:

• Moisture or cleaning solution seepage
• Food debris under the buttons
• Electronic glitch

Quick fixes:

1. Turn off the power at the circuit breaker for 2-3 minutes
2. Clean the control panel thoroughly with a dry cloth
3. Check for stuck buttons and gently clean around them

3. Power Surge Effects

Recent power surges can cause electronic controls to malfunction.

Solution: Reset the cooktop by disconnecting it from power for 5 minutes, then reconnecting.

4. Faulty Control Board

If the control board is malfunctioning, it might send incorrect signals to the indicator lights.

Diagnostic check: If the lights stay on after trying all previous solutions and the cooktop has been completely cool for hours, the control board might need replacement.

5. Sensor Malfunction

Temperature sensors can become faulty, causing incorrect readings and keeping lights on.

Professional diagnosis needed if:

• Lights stay on for more than 1 hour after cooling
• Other cooking functions are affected
• You notice irregular behavior in temperature control

When to Call a Professional

Contact a qualified appliance repair technician if:

• The lights remain on after trying all reset procedures
• You notice any burning smell or unusual noises
• The cooktop shows other signs of malfunction
• Your cooktop is still under warranty

Prevention Tips

To avoid future issues:

• Clean the cooktop regularly using appropriate cleaning products
• Avoid letting liquids seep into control panels
• Don't use excessive force when pressing buttons
• Consider using a surge protector for your kitchen appliances

⚠️ Always ensure the cooktop is actually off, regardless of indicator lights. If you smell gas or notice any unusual behavior, disconnect the power and contact a professional immediately.
