How to Fix / Troubleshooting

Safety: Turn off gas and power before working near gas valves. Do not disassemble gas valves beyond manufacturer guidance.

  • Clean exterior: Remove knobs and clean around the valve stems with a mild cleaner; avoid spraying directly into the valve.
  • Check knob fit: Ensure knobs are not cracked or rubbing against the panel; replace if damaged.
  • Lubrication: Internal valve lubrication should only be done with gas‑rated lubricants and typically by a technician. Do not use household oils.
  • Valve replacement: If stiffness persists or control is erratic, the gas valves may need replacement by a qualified gas technician.
