Step-by-step fix
Step 1: Confirm the radiant element is the likely problem
- Make sure the problem follows one burner location, not every burner on the cooktop.
- Look for signs that point to a failed element: the burner stays cold, only part of the ring glows, heating is weak, or the element area shows blistering or visible damage under the glass.
- Try a different control setting on that same burner to rule out a simple setting issue.
- If you can safely access the underside later, compare the suspect element to the others for obvious burn marks or a broken support.
If it works: You have good reason to suspect the cooktop radiant surface element at one burner position.
If it doesn’t: If the burner works normally sometimes, multiple burners have the same issue, or the indicator lights and controls act strangely, the problem may be a switch, control, wiring, or power supply instead.
Stop if:- The cooktop glass is cracked.
- You smell burned insulation, see melted wiring, or find signs of arcing beyond the element area.
- The problem affects several burners or the whole cooktop, which points away from a single element.
Step 2: Shut off power and get the cooktop ready to open
- Turn off the cooktop at the breaker. Do not rely only on the control knobs being off.
- Verify power is off before touching internal parts.
- Let the cooktop cool fully if it was recently used.
- Clear the surrounding counter space and place a towel or cardboard nearby to protect the surface if needed during access.
If it works: The cooktop is cool, de-energized, and safe to open.
If it doesn’t: If you cannot confirm power is off, do not continue until you can verify it with certainty.
Stop if:- You cannot identify the correct breaker.
- Any part of the cooktop still shows live power when tested.
Step 3: Open the cooktop and locate the bad element
- Remove the screws or fasteners that secure the cooktop or lift the top according to the way your unit is mounted.
- Raise the cooktop carefully and support it so it does not drop or twist.
- Find the radiant element for the failed burner position.
- Take a clear photo of the wire connections before disconnecting anything.
- Inspect the element bracket, insulation, and nearby wires for heat damage.
If it works: You can clearly access the old cooktop radiant surface element and have a reference photo of the wiring.
If it doesn’t: If access is blocked, look for additional trim screws or mounting clips and open only as much as needed to reach the element safely.
Stop if:- The support frame is bent or broken.
- Wire terminals, insulation, or connectors are badly burned and need more than a simple element swap.
- Lifting the top puts stress on cracked glass or damaged mounting points.
Step 4: Remove the old radiant element
- Label the wires if the terminals are close together or easy to confuse.
- Pull each wire terminal off the old element by gripping the connector, not the wire itself.
- Remove the clips, screws, or brackets holding the element in place.
- Lift the old element out carefully, keeping any spacers or supports in the same order for reuse if the new part does not include them.
If it works: The old element is out and the wiring is intact.
If it doesn’t: If a connector is stuck, use needle-nose pliers and gentle rocking pressure instead of pulling harder on the wire.
Stop if:- A wire terminal breaks off or the wire pulls out of its connector.
- You find the mounting hardware or support pieces are heat-damaged and no longer secure the element properly.
Step 5: Install the new cooktop radiant surface element
- Compare the new element to the old one for size, terminal layout, and mounting points before installing it.
- Set the new element into the same position and reinstall any brackets, clips, or screws so it sits flat and secure.
- Reconnect the wires one at a time using your photo as a guide.
- Check that each terminal is fully seated and that no wire is pinched, rubbing sharp metal, or resting where it can overheat.
If it works: The new element is mounted securely and wired the same way as the original.
If it doesn’t: If the new part does not match the old one closely, stop and verify the replacement using your cooktop model information.
Stop if:- The replacement part does not match the original terminal layout or mounting style.
- Any connector fits loosely enough that it could overheat during use.
Step 6: Reassemble and test the repair in real use
- Lower the cooktop carefully and reinstall the mounting screws without overtightening.
- Restore power at the breaker.
- Turn the repaired burner on at a low setting first, then increase the heat and watch for normal, even heating.
- Test with a pan of water or normal cookware to confirm the burner cycles and heats as expected.
- Check that nearby burners and controls still operate normally after reassembly.
If it works: The repaired burner heats normally, cycles as expected, and the cooktop goes back together without loose parts or new issues.
If it doesn’t: If the new element does not heat, heats constantly, or only works on some settings, recheck the wire placement and consider a bad switch, control, or damaged wiring.
Stop if:- You see sparking, smell burning insulation, or notice smoke.
- The burner overheats immediately or will not shut off.
- The cooktop glass or frame does not sit correctly after reassembly.

FAQ
How do I know the radiant surface element is bad and not the switch?
A bad element often shows weak heating, partial glowing, or visible damage at one burner position. If the burner will not regulate heat, stays on all the time, or several burners act up, the switch or another control part may be the real problem.
Can I replace a radiant element without removing the whole cooktop?
Usually you need to lift or open the cooktop to reach the element from below. The exact access method varies, but most replacements require at least partial disassembly.
Do I need a multimeter for this repair?
It helps, especially to confirm power is off and to compare the old element if needed, but the repair is often done by matching the failed burner position, visible damage, and wire layout carefully.
What if the new element still does not heat?
First recheck the wire connections against your photo and make sure each terminal is fully seated. If the wiring is correct, the issue may be the burner switch, control, incoming power, or damaged wiring.
Can I keep using the cooktop if one radiant element is damaged?
It is better not to use that burner until it is repaired. A damaged element or overheated connector can get worse and may damage nearby wiring or the cooktop surface.
