A healthy burner flame hugs the burner ports and burns steadily. A flame that lifts away, flickers or pops points to a change in how gas and air mix, and on an older cooktop that is often down to buildup.
What You See and What It Can Mean
- Lifting flames. Too much gas pressure or blocked air openings can push the flame off the ports.
- Popping at ignition. Gas collects before it lights. A damp igniter or a dirty port often explains it.
- Flames on one side only. A clogged port or a cap that is out of place.
- Yellow tips. Poor air mix or grease on the burner.
Simple Steps
- With the cooktop off and cool, lift the grate and cap.
- Clean the cap and burner with a soft brush and warm, soapy water. Dry everything.
- Clear port openings gently. Do not widen them.
- Reseat the cap and light the burner to compare.
What Could Be Behind a Lifting Flame
A regulator that has drifted, or a cooktop set up for the other fuel, can give a lifting flame. Gas pressure and conversion are not do-it-yourself work. A licensed plumber handles the gas supply, and we handle the cooktop itself.
A Safety Rule That Does Not Change
If you smell gas, do not use the cooktop. Leave the kitchen, keep ignition sources away and phone your gas utility from a safe place outdoors.
Once the cooktop is repaired, we check every burner for a steady blue flame, so you leave knowing which burners were adjusted, and we say so when an older part is the limit.
A flame that still lifts after cleaning needs testing. Call us or use our online form, and we confirm a three-hour arrival window for your cooktop repair.
