Direct answer: A Frigidaire cooktop burner that is not heating is usually one of two problems: an electric surface element is not making a good connection or has failed, or a gas burner is not lighting because the cap, burner head, or igniter area is dirty or misaligned.
Most likely: Start by identifying whether you have an electric radiant/coil burner that stays cold, or a gas burner that clicks but never lights. Those look similar from the kitchen, but the fix path is completely different.
Check the simple visible stuff first. If only one burner is acting up and the rest of the cooktop works normally, the fault is usually right at that burner, not the whole appliance. Reality check: one dead burner is commonly a local part failure, not a full cooktop failure. Common wrong move: scrubbing a gas igniter hard or forcing an electric coil into the socket and damaging the receptacle.
Don’t start with: Do not start by ordering a switch or taking the cooktop apart. Most no-heat calls on one burner come down to a loose electric element fit, a bad surface element, or a gas burner cap and head that are out of place or clogged.
You hear repeated clicking, may smell a little gas, but the burner never lights or only lights after several tries.
Start here: Start with burner cap alignment, burner head seating, and clogged flame ports around that burner.
The burner turns on but does not heat, or only heats after you move the element or knob around.
Start here: Start with the burner itself and its connection point before blaming the switch.
It may work on one setting, cut in and out, or come back briefly after reseating or cleaning.
Start here: Look for a loose electric element connection, a worn cooktop burner receptacle, or a dirty gas burner assembly.
The rest of the cooktop works normally, so power or fuel to the whole unit is probably still present.
Start here: Focus on the failed burner's own parts first, not the whole cooktop.
On gas models, one burner that clicks but will not light is often just not directing gas to the igniter correctly because the cap is off-center or the ports are blocked with spill residue.
Quick check: With the burner cool, lift and reseat the cap and burner head exactly in place, then clear visible food crust from the flame ports with a wooden toothpick or soft brush.
On electric models, a single burner that stays cold or only works when moved is very often a bad surface element, especially on plug-in coil styles.
Quick check: Remove the cool element if your style allows it and look for blistering, cracks, burn spots, or loose prongs.
If the electric burner works only after wiggling, the element may be fine but the receptacle contacts are heat-damaged and no longer gripping well.
Quick check: Inspect the burner socket area for discoloration, melted plastic, looseness, or pitted contacts.
If the burner and connection look sound but that burner still never heats, the switch behind the knob becomes the next likely part on electric models.
Quick check: Compare behavior on all heat settings. A burner that never responds on any setting, with a good element and good receptacle, points toward the switch.
You can waste a lot of time chasing the wrong parts if you do not sort out the burner type first.
Next move: You now have the right path and can stay focused on the failed burner itself. If you cannot tell what type you have or the symptoms do not match either pattern, do not guess at parts.
What to conclude: Single-burner gas problems usually live at the cap, head, or igniter area. Single-burner electric problems usually live at the surface element, receptacle, or burner switch.
Most one-burner failures show themselves with a plain visual check before any disassembly.
Next move: If the burner lights or heats normally after reseating and cleaning, the problem was likely poor alignment or residue buildup. Move to the connection check. A burner that still fails after a clean reseat usually has a worn connection or a failed burner part.
What to conclude: Gas burners need the cap and head positioned correctly to light. Electric burners need a solid, clean connection and an intact heating element.
This is the cleanest way to tell whether the burner itself is bad or the cooktop connection is bad, especially on electric coil models.
Next move: If the problem follows the electric element, replace the cooktop surface element. If the problem stays at the same spot, keep going and inspect the receptacle or switch. If you cannot swap safely or the results are mixed, use the next step to inspect the connection point closely.
Once the burner itself is ruled in or out, the next likely failure is the connection point or the switch for that burner.
Next move: If you found a burned receptacle, failed element, or clearly bad burner assembly, you have a solid repair direction. If nothing looks wrong but the burner still will not heat, the repair is moving beyond simple visible diagnosis.
By now you should have enough evidence to replace the right burner-level part instead of guessing.
A good result: The burner should light or heat promptly and respond normally across its settings.
If not: If the new confirmed part does not fix it, the problem is likely in internal wiring or cooktop controls and is no longer a good guess-and-buy repair.
What to conclude: A clean part match at this stage usually solves a one-burner failure. If it does not, the fault is deeper than the burner-level parts covered here.

If the other burners work, the problem is usually local to that burner. On electric models, that usually means the cooktop surface element, burner receptacle, or burner switch. On gas models, it is often a misaligned burner cap, clogged burner ports, or a problem at the igniter area.
On a plug-in electric coil style, the best clue is whether the problem follows the element when you swap it with another same-size burner. Visible blistering, cracks, or burned prongs also point to a failed cooktop surface element.
Yes. A gas burner needs the cap and burner head to sit correctly so gas reaches the igniter and spreads around the burner. Food crust, grease, or a cap sitting slightly off-center can be enough to cause clicking with no flame.
Usually no. The switch is not the first part to guess on a one-burner no-heat problem. Rule out a bad cooktop surface element and a burned cooktop burner receptacle first, because those are more common and easier to confirm.
Only briefly. A few short tests are fine, but if gas odor builds up or the burner keeps clicking without lighting, stop. Shut it off, ventilate the area, and fix the seating, cleaning, or igniter issue before trying again.
