one of my sealed burners on my ge range has a super low flame, like a little ring, even on the high setting.

Diagnosis

The "ring of fire" or low-flame symptom on the GE JGBS66REKSS is almost always caused by a partial obstruction in the burner ports or a misalignment of the burner cap. Because these are "sealed" burners, they are designed to prevent spills from entering the internal combustion chamber, but this design means that boiled-over liquids, fats, and cleaning agents often bake into the tiny precision-drilled holes (ports) around the perimeter of the aluminum burner head. When a port is partially clogged, the gas cannot flow evenly, creating a localized "cold spot" or a very weak flame that refuses to reach full height even when the knob is turned to the High setting. You can confirm this by removing the burner cap; if the flame is strong and consistent without the cap on, the blockage is likely in the cap's underside. If the flame is still weak and patchy without the cap, the blockage is located within the burner head ports themselves.

How to Fix It

To restore full BTU output to the affected burner, follow these precise cleaning and calibration steps:

1. Ensure the range has cooled completely and the gas supply is off or the knobs are in the 'Off' position.
2. Lift the heavy cast-iron grate and carefully remove the circular burner cap. Set it aside on a soft surface to avoid scratching the enamel.
3. Examine the aluminum burner head. Use a thin, stiff sewing needle or a 0.5mm precision pin to manually poke through every single small hole around the perimeter of the burner head. Do not use a wooden toothpick, as these can snap off and permanently plug the port.
4. Use a vacuum with a brush attachment or a can of compressed air to blow out any loosened debris from the center of the burner assembly.
5. Submerge the burner cap in a mixture of warm water and a degreasing dish soap. Use a nylon scrub brush to clean the underside of the cap, specifically focusing on the radial slots where the gas exits.
6. Thoroughly dry the burner head and cap using a lint-free cloth or a hairdryer. Any moisture left in the ports will cause an uneven flame or "popping" sounds upon ignition.
7. Place the burner cap back on the head. Ensure it sits perfectly flat; if the cap is tilted even slightly, it will disrupt the gas flow and cause a low flame on one side.

If That Didn't Work

• Check the Orifice: If cleaning the ports didn't help, the brass gas orifice (the small nozzle underneath the burner head) may be clogged. Use a needle to gently clear the center hole of the orifice, but be extremely careful not to scratch the interior of the nozzle, as this can change the gas flow rate and cause an oversized, dangerous flame.
• Inspect the Igniter Electrode: Ensure the ceramic igniter probe is not coated in carbon buildup or food residue. If the probe is dirty, it can interfere with the initial gas ignition sequence, causing the burner to struggle to maintain a high flame. Clean the tip with a cotton swab dipped in rubbing alcohol.
• Verify Gas Pressure: If multiple burners are exhibiting this low-flame behavior, the issue may be your home's gas regulator or a partially closed shut-off valve. Ensure the main gas valve behind the range is open fully.
• Replace the Burner Head: If the aluminum burner head has suffered deep corrosion or "pitting" from acidic food spills, the ports may be permanently compromised. Replace the burner head assembly with the GE-specific part for the JGBS66 series.

Heads Up

• Never use bleach or caustic oven cleaners on the aluminum burner heads, as these chemicals can eat through the metal and enlarge the ports, leading to an unstable and dangerous flame.
• Avoid using "deep cleaning" aerosols directly into the burner ports, as the residue can create a chemical film that attracts more debris.
• Always ensure the burner cap is seated correctly before lighting; a misplaced cap can cause gas to build up under the surface, resulting in a loud "whoosh" or a small flash-fire when ignited.
• Perform a "port check" every three months by visually inspecting the holes for white or brown crusty deposits to prevent total burner failure.
