Kenmore Electric Range Burners Wouldn't Regulate Temperature — Dual Infinite Switch Replacement

Customer Complaint

The customer reported that both front burners would not maintain the selected cooking temperature.

The burners either overheated or failed to regulate properly during cooking.

Technician Inspection

Testing confirmed that both front infinite burner switches were defective.

The switches could no longer properly cycle electrical power to the heating elements, causing poor temperature control.

Both switches were replaced.

Failure Analysis

Infinite Switch Wear

Infinite switches are responsible for cycling power on and off to electric surface burners.

As they wear over time, the internal contacts can fail, causing burners to:

• Stay on high heat
• Not reach the selected temperature
• Heat inconsistently
• Fail to respond to knob adjustments

Replacing the defective switches restores normal burner control.

Preventive Maintenance Tips

Help reduce wear on your range's surface elements and control switches:

✅ Clean Up Spills Quickly

Prevent liquids from seeping beneath the control knobs where they can short out the infinite switches behind the panel.

✅ Match Pot Size to Burner Size

Using undersized or oversized pots can trap excessive heat, damaging the surface element and the surrounding stove top.

✅ Avoid Dropping Heavy Cookware

Heavy impacts can break the heating element structure and damage the receptacle connections.

✅ Don't Ignore Temperature Issues

If a burner stops regulating heat, discontinue use immediately until repaired to prevent fire hazards or further electrical damage.

Frequently Asked Questions

1. Why is my Kenmore range burner not regulating temperature?

The most common reason a Kenmore range burner fails to regulate temperature is a faulty infinite switch. This component controls how much voltage is sent to the burner. When its internal contacts wear out, it loses the ability to properly cycle the heat on and off.

2. What does it mean when an electric stove burner stays on high?

When an electric stove burner stays on high regardless of the knob setting, the infinite switch has likely shorted closed. This creates a direct, uninterrupted path of electricity to the heating element. You should unplug the stove or switch off its breaker until a proper infinite switch replacement can be performed.

3. Can I fix a broken stove burner without replacing the whole stove?

Yes. A stove burner control switch replacement is a highly economical repair. Replacing the specific failed component easily restores full function to your electric range, sparing you the heavy cost of a brand new appliance.
