Direct answer: If one Samsung cooktop burner gets much hotter than the setting, the usual causes are a stuck burner control switch, a damaged radiant surface element, or a pan and sensor mismatch on a burner that is otherwise working normally.
Most likely: Start with the exact pattern: one burner only, all settings too hot, or a burner that stays on high no matter where the knob is set. A single burner stuck on high points first to that burner's control switch.
First figure out whether the burner is truly failing or just acting normal for the pan and setting you’re using. Reality check: electric cooktop elements often run red-hot for short stretches even on medium settings before they cycle off. Common wrong move: swapping parts before checking whether the burner actually cycles down after a few minutes with a flat pan in place.
Don’t start with: Don’t start by ordering a new burner just because it glows bright red. Many overheated-burner complaints are really a bad control switch or the wrong cookware on a sensor-style element.
Low, medium, and high all feel nearly the same, and the burner may stay bright longer than the others.
Start here: Start with the burner control switch for that position, then compare the burner’s cycling pattern to a similar burner.
The burner does cycle, but the pan gets hotter than expected and delicate cooking is hard to control.
Start here: Start with cookware fit and burner size match before assuming a failed part.
You lower the knob but the burner keeps pushing hard heat for several minutes without backing off.
Start here: Watch for a true no-cycle condition. If it never eases off, suspect the burner control switch first.
A thin or warped pan runs hot spots, scorches oil, or boils unevenly while other pans behave better.
Start here: Check the pan bottom for flatness and size match to the burner before opening the cooktop.
When one burner acts like high heat no matter where the knob is set, the control switch is the most common culprit on an electric cooktop.
Quick check: With a pan of water on the burner, move from high to low and watch for cycling. If the burner never noticeably backs off, the switch is likely stuck closed.
A damaged surface element can heat unevenly, run hotter in one section, or fail to cycle the way a matching burner does.
Quick check: Compare glow pattern and heat response to a same-size burner. Dark spots, hot rings, or obvious uneven heating point toward the surface element.
A thin or bowed pan can make a normal burner seem too hot because heat concentrates in one spot instead of spreading across the pan bottom.
Quick check: Set a straightedge across the pan bottom or try a different flat, heavier pan on the same burner at the same setting.
If more than one burner runs too hot, or the heat behavior is erratic instead of simply stuck on high, the problem may be beyond a single switch or element.
Quick check: See whether multiple burners show the same symptom and whether the control response is delayed, inconsistent, or paired with other control problems.
Electric cooktop burners do not hold one steady glow. They heat hard, then cycle. A normal burner can look too hot if you judge it by color alone.
Next move: If the suspect burner behaves about like the matching burner, the cooktop may be normal and the issue may be pan choice or heat-setting expectations. If the suspect burner clearly runs harder than a matching burner at the same setting, keep going.
What to conclude: This separates normal cycling from a true overheat complaint so you don’t replace parts for a burner that is actually working.
A warped or lightweight pan is one of the most common reasons homeowners think a burner is too hot, especially when simmering or frying.
Next move: If a different pan fixes the problem, the burner is likely fine and you can stop here. If multiple good pans still overheat on that one burner, move on to the control check.
What to conclude: If the symptom follows the pan, you have a cookware problem. If it stays with one burner, the cooktop itself needs attention.
A burner control switch that sticks closed will keep feeding full heat even when you turn the knob down.
Next move: If the burner responds clearly to lower settings and cycles down, the switch may be okay and the element or control logic becomes more likely. If the burner acts nearly the same on every setting, the burner control switch is the leading failure.
A damaged radiant surface element often gives itself away by heating unevenly, cycling oddly, or creating hot spots that a good burner does not.
Next move: If the suspect burner matches the good burner in cycling and heat spread, the issue is less likely the surface element itself. If the suspect burner shows obvious uneven heating or a strange glow pattern, the cooktop radiant surface element is the stronger repair path.
By now you should know whether this is one bad control, one bad element, or a wider control problem that is not a good guess-and-buy situation.
A good result: If the symptom points cleanly to one switch or one element, you have a realistic next repair step.
If not: If the pattern is inconsistent, affects multiple burners, or you are not confident which part failed, don’t guess on parts.
What to conclude: Single-burner overheating usually has a single-burner fix. Multi-burner overheating usually means the problem is higher up in the cooktop controls.

That can be normal. Electric surface elements often heat bright red, then cycle off and back on to average the selected temperature. The problem is when one burner stays at full heat much longer than the others or ignores lower settings.
Not always. A stuck cooktop burner control switch is often the real cause when one burner acts like high heat on every setting. The element becomes more likely when the heat pattern is uneven or the burner has obvious hot spots.
Yes, but usually only if the knob is cracked, melted, or loose enough that it is not turning the control shaft correctly. A bad knob is less common than a failed control switch.
Start with the pan. A warped or thin pan can create hot spots and make a normal burner seem too aggressive. If several good pans all scorch on the same burner, then look at the control switch or surface element.
No. If the burner does not respond to lower settings or keeps heating after you turn it off, stop using that burner and shut off power to the cooktop until it is repaired.
That points away from a single burner switch or element and more toward a broader cooktop control problem. At that point, it is better to stop at diagnosis and have the cooktop professionally tested rather than guessing on parts.
