Possible Causes

Grease or debris inside valve, Worn valve stem, Damaged valve body, Misaligned knob or bezel

How to Fix / Troubleshooting

Safety first: Turn off gas and power. Do not force a stuck valve; it may crack and leak.

  • Remove knob: Pull the burner knob straight off the valve stem. Inspect for cracks or deformation.
  • Clean area: Wipe away grease and debris around the stem and bezel with a mild degreaser.
  • Do not lubricate internally: Do not spray lubricants into the gas valve; this can damage seals and create a hazard.
  • Check alignment: Ensure the knob and bezel are correctly oriented and not rubbing against the panel.
  • Replace valve: If the valve remains stiff or does not shut off reliably, the BlueStar surface burner valve should be replaced by a qualified technician, as this involves gas line disconnection and leak testing.
