JennAir Rangetop Flame Lifting, Popping or Roaring When Lit

A healthy gas flame is steady and mostly blue, sits close to the burner, and makes only a soft hiss. When it lifts away, pops or roars, the mixture of gas and air is off or something is blocking the flow.

Common Reasons

• A misplaced burner cap: the cap is not seated flat, so the flame comes out unevenly.
• Spills in the ports: food or grease partly blocks the small openings.
• Moisture: water from cleaning or humid air can cause popping for a minute or two.
• Gas type or pressure: a unit set for the wrong fuel, or changes in supply, can lift the flame.
• Drafts: a strong fan or open window can push the flame sideways.

Safe Checks

1. Shut the burner off and give it time to cool.
2. Lift the cap and check that it rests level on its base.
3. Clean the cap and ports with a soft brush, never with metal wire.
4. Dry everything and light the burner again.

When to Stop Using the Burner

Stop and call us if flames are tall and yellow, if you see soot on pans, if the flame will not stay lit, or if you smell gas. If you ever smell gas, avoid light switches and go outdoors, then phone your gas utility.

Orange or yellow flames can also mean poor combustion, which may produce carbon monoxide. A carbon monoxide alarm in the hallway outside the kitchen is a smart safeguard.
