Answer to continue safely
Is it safe to keep using?
Maybe. An uneven flame is not an immediate safety emergency if the burner ignites cleanly and stays lit. However, uneven combustion reduces cooking performance and can develop into a yellow flame condition. Clean the burner cap and reseat it before continued use. Do not use if the flame turns yellow or develops a gas odor.
Can I reset the code?
No. UNEVEN is caused by a physical gas distribution problem, not a control board error. Resetting the rangetop will not change the flame pattern. Cleaning and correctly reseating the burner cap is the required remedy.
When to stop immediately?
Stop if you notice: Any portion of the uneven flame turns yellow or produces soot., Gas odor is present with the burner lit..
Symptoms You May Notice
Flame is taller on one side of the burner ring
The burner ring flame is visibly higher on one arc and lower or absent on the opposite side, confirming uneven gas distribution across the burner cap ports.
Cookware heats unevenly across the bottom
Food or liquid in a pan heats noticeably faster on one side, confirming that the asymmetric flame is delivering heat unequally to the cookware.
Gaps visible in the flame ring
One or more sections of the burner ring show no flame at all while adjacent sections burn normally, indicating those specific ports are fully blocked.
Flame lifts or spits at certain positions
At specific points around the ring the flame lifts away from the burner cap or pulses erratically, suggesting partially blocked ports forcing gas flow through adjacent openings.
Possible Causes
Selectively clogged burner cap ports
Dried food residue or boilover material has blocked specific ports on one side of the burner cap while leaving others clear, creating the asymmetric flame pattern.
DIY PossibleMisaligned or warped burner cap
A burner cap that is off-center, tilted, or warped from heat does not distribute gas uniformly around the ring, producing uneven combustion even with clean ports.
DIY PossibleDamaged or corroded burner head
The burner head casting itself is cracked or corroded, creating an uneven gas distribution channel that cannot be corrected by cleaning alone.
Requires ProfessionalSafe Checks You Can Do
-
1
Remove and thoroughly clean the burner cap
Remove the burner cap and soak it in warm soapy water for 20 minutes. Use a straightened paper clip to individually clear every port hole, then rinse thoroughly, dry completely, and reseat.
Hold the clean cap up to a light source and look through each port — it should be clear. Any that remain dark after cleaning are still clogged.
-
2
Reseat the burner cap correctly
Place the clean, dry burner cap on the burner base and confirm it sits flat — no tilting or rocking. Align the locating pin with the corresponding notch. Even a 1 mm tilt can redirect gas flow and create an uneven flame.
After seating, press down gently on opposite edges to confirm the cap is fully flat. Rocking means the pin isn't engaged.

3
Inspect the burner cap for warping or damage
Place the clean burner cap on a flat surface (such as a countertop) and check whether it sits flat without rocking. A warped cap cannot distribute gas evenly regardless of how clean the ports are.
Burner caps exposed to repeated boilovers or high heat can warp slightly over time. A warped cap needs replacement, not further cleaning.
When to Call a Professional
Contact a qualified technician if:
- UNEVEN persists after thorough cap cleaning and confirmed flat reseating.
- Burner cap is visibly warped and needs replacement.
- Burner head casting shows visible cracks or heavy corrosion.
