Stove Burner Not Working: Causes & Fixes
A non-heating stove burner is usually caused by a faulty coil element, a broken infinite switch, or a loose connection—not a broken stovetop. Most electric coil replacements cost between 15 and 40 dollars and take under an hour, making this a common DIY fix that saves you 150 to 300 dollars in service calls. Gas burners may require a clogged port cleaning or igniter replacement, both straightforward tasks.
Step-by-Step Fix
- 1
Turn off the power and cool the burner
Switch off the breaker for your electric stove or turn off the gas supply valve if you have a gas model. Wait at least 30 minutes for the burner to cool completely before touching any components to avoid burns.
- 2
Inspect the coil or burner head for damage
For electric coil burners, look for cracks, blistering, or burn marks on the heating element. For gas burners, check that the burner cap is centered and the ports are not clogged with food or debris. Clean gas ports with a thin wire or needle if you spot blockages.

Test and replace the heating element if needed
Lift or twist out the coil element (depending on your model) and plug in a known-working coil from another burner to test. If the test coil heats, your original element is faulty and needs replacement; order the exact model number from your stove's manual or the manufacturer's website.

Check the infinite switch connection
If swapping the coil does not work, the infinite switch (the dial control) may be faulty. Remove the switch knob and inspect the terminals for corrosion, loose wires, or burnt contacts. Gently push terminals back into place if loose, or order a replacement switch for 25 to 60 dollars.
- 5
Reinstall the element and restore power
Slide or twist the new coil firmly into its socket until it clicks or seats fully. Restore power at the breaker or reopen the gas valve, then test the burner on medium heat for 2 to 3 minutes to confirm it heats evenly.
⚠️ Safety Notes
- Always turn off the power at the breaker or close the gas valve before removing or testing any burner element to prevent electrical shock or gas leaks.
- Do not touch the burner coil immediately after power is restored; it will be extremely hot within seconds.
- If you smell gas after relighting a gas burner, turn off the valve, leave the area, and call your gas company from outside—do not use electrical switches or create sparks.
When to Call a Pro
Call a professional if the burner still does not heat after replacing the coil and infinite switch, or if you see burn marks, melted plastic, or signs of internal damage inside the stovetop housing. Also contact a technician if your gas burner igniter produces no spark after cleaning or if you suspect a wiring short.
Frequently Asked Questions
- Why is my stove burner not heating up?
- The most common causes are a burnt-out coil element (electric), a faulty infinite switch, a loose connection, or a clogged gas port (gas). You can test by swapping the non-working coil with a working one from another burner; if heat returns, the element is the problem.
- How much does it cost to replace a stove burner coil?
- Replacement coil elements typically cost 15 to 40 dollars depending on the brand and model, and you can buy them online or at appliance supply stores using your stove's model number.
- Can I replace a stove burner element myself?
- Yes, replacing an electric coil burner is a simple DIY task that takes 5 to 10 minutes once you have the correct replacement part; just lift or twist out the old element and slide in the new one.
- What does a bad infinite switch look like?
- A faulty infinite switch often shows corroded or blackened terminals, loose wire connections, or a knob that does not click or turn smoothly; replacement costs 25 to 60 dollars.
- How do I clean a clogged gas stove burner?
- Remove the burner cap and grate, then use a thin wire, toothpick, or needle to gently poke out food, grease, or mineral deposits from each port hole; soak the cap in warm soapy water and dry thoroughly before reinstalling.
