Common cooktop range burner issues and how to fix them

Sometimes you set a burner to low or medium heat, and it stubbornly stays on high—or maybe the burner just doesn’t respond as it should. Let’s talk about what usually causes that and how you can fix it.

What Causes This Problem?

In most cases, when a burner is stuck on one heat level—especially if it stays on high—it’s often a faulty infinite switch behind the knob. That switch controls how much power goes to the burner coil. Over time, these switches can wear out, burn out, or just fail, causing the burner to behave unpredictably.

Also, to find the correct part number, you’ll need to locate your model and serial number. Usually, for ranges, you can find this info behind the door or behind the bottom drawer on the front part of the range body. For built-in cooktops, it’s typically located underneath the cooktop. I’ll attach some pictures with arrows pointing out these spots so you can easily find it.

How to Fix It

Replacing that infinite switch is usually a pretty straightforward repair that a handy person can handle. You’ll want to make sure you’ve got the correct model and part number for your specific range, since different burners and switches can vary even on the same appliance. And always remember: safety first. Unplug the range or turn off the breaker before you do anything to avoid any risk of electric shock.

In Conclusion

In conclusion, using original manufacturer (OEM) parts is really worth it. While cheaper replacement switches might be tempting, they often fail faster. With an OEM part, you’re more likely to have a long-lasting fix and avoid repeated repairs.
