Direct answer: If one electric cooktop burner is not heating, the usual causes are a failed cooktop surface element, a loose or heat-damaged burner receptacle where the element plugs in, or a bad cooktop burner switch behind the knob. Start by separating a removable coil burner problem from a smooth-top radiant burner problem, then check for obvious heat damage before buying anything.
Most likely: On coil-style electric cooktops, the most common fix is the cooktop surface element or the burner receptacle it plugs into. On smooth-top units, a dead burner often points to the cooktop burner switch or the radiant element under the glass.
First figure out whether only one burner is affected or the whole cooktop has a power problem. If the other burners work normally, stay focused on that one burner circuit. Reality check: a burner can look fine and still be open internally. Common wrong move: forcing a coil element into the socket and spreading or burning the receptacle even worse.
Don’t start with: Do not start by replacing the cooktop control switch just because the burner is dead. A burned element connection is more common and easier to confirm.
The removable coil burner never glows or warms up, while the other burners still work.
Start here: Start with burner seating, swap that coil with a same-size working burner if you have one, and inspect the receptacle for scorching.
The glass top looks normal, but that heating zone stays cool or barely warms while the rest of the cooktop works.
Start here: Start by confirming the correct burner selector and heat setting, then move to the cooktop burner switch and radiant element branch.
The burner may heat on high but not low, or it cuts in and out in a way that is not normal cycling.
Start here: That pattern leans toward a failing cooktop burner switch more than a dead element.
A coil burner may come on briefly after being reseated, then quit again.
Start here: Treat that as a connection problem first and inspect the cooktop burner receptacle for looseness, pitting, or melted insulation.
A surface element can open internally and stop heating even when it still looks intact from the top.
Quick check: On a coil cooktop, swap the same-size burner with a working one. If the problem follows the burner, the element is bad.
Coil burners plug into a receptacle that often overheats, pits, or loosens after years of use. That can leave the burner completely dead or intermittent.
Quick check: Pull the burner and look for blackening, melted plastic, loose terminals, or a burnt smell at the socket.
If the burner does not respond correctly to the knob, only heats on certain settings, or a smooth-top zone stays cold with no visible connection issue, the switch is a strong suspect.
Quick check: Compare knob feel and behavior to a working burner. A switch that feels loose, gritty, or inconsistent is suspect, especially when the element and wiring look okay.
Heat damage under the top or behind the control area can open the circuit to one burner, especially after a receptacle has been running hot.
Quick check: With power disconnected, look for charred wire ends, brittle insulation, or a terminal that has overheated near the burner connection or switch.
If multiple burners are dead or the cooktop lost power after a trip, you do not want to tear into one burner first.
Next move: If the other burners work, stay with the dead burner circuit and keep going. If none of the burners heat, this page is no longer the best fit. You likely have a cooktop power supply problem, terminal issue, or breaker problem.
What to conclude: A single dead burner usually points to that burner's element, receptacle, switch, or local wiring rather than the whole appliance.
These two styles fail differently, and the fastest check on a coil burner is often a simple swap test.
Next move: If reseating fixes it, the burner may simply have had a poor connection, but keep an eye on it. If the problem returns, the receptacle is likely heat-damaged. If a coil burner stays dead after reseating, use the swap result to decide whether the element or the socket is at fault. If a smooth-top burner is still dead, move on to the switch and wiring checks.
What to conclude: A coil burner that fails in any location is usually a bad cooktop surface element. A good burner that stays dead in one spot points to the cooktop burner receptacle, switch, or wiring.
Burned connections are common on electric cooktops and are often visible before you test anything else.
Next move: If you find obvious burning at the socket or wire ends, you have a solid repair direction and can stop guessing. If everything looks clean and intact, the failure is more likely inside the element or the cooktop burner switch.
By now you should have enough evidence to avoid guess-buying.
Next move: If your diagnosis matches one of these patterns cleanly, you can move ahead with the repair instead of replacing multiple parts. If the clues conflict or you cannot access the burner circuit safely, stop here and have an appliance tech test the circuit with the right meter.
A burner that heats once after repair is not enough. You want to know the connection is solid and the control responds normally.
A good result: If the burner heats a pan normally and responds across settings, the repair is holding.
If not: If the burner is still dead, only works on one setting, or the connection starts to smell hot again, disconnect power and move to a pro diagnosis or the remaining confirmed part branch.
What to conclude: A good repair gives you stable heat without arcing, burning smell, or erratic control behavior.

That usually means the problem is local to that burner circuit, not the whole cooktop. On coil models, the cooktop surface element or burner receptacle is most common. On smooth-top models, the cooktop burner switch or radiant element is often next in line.
On a coil cooktop, swap the dead burner with a same-size working burner. If the suspect burner stays dead in the good spot, the cooktop surface element is the likely failure. If the good burner also stays dead in the original spot, look at the receptacle or switch instead.
Yes. A loose or heat-damaged cooktop burner receptacle is a very common cause. Look for blackened contacts, melted plastic, widened terminals, or a burnt smell. A known good burner that will not heat in that position is a strong clue.
Usually not. A burner that heats only on high or acts wrong at certain settings points more toward the cooktop burner switch than the element itself.
No. That usually means a loose or burned connection. It may heat for a while, but it can also arc and overheat the receptacle or wiring. Shut off power and inspect the burner connection before using it again.
Not exactly. Coil burners give you an easy swap test because the element is removable. Smooth-top burners are fixed under the glass, so diagnosis leans more on the control behavior, visible wiring condition, and access to the burner circuit.
