How to Fix / Troubleshooting

Safety first: For gas valves, do not apply lubricants without manufacturer approval. Turn off gas and power before removing knobs.

  • Remove knobs: Pull knobs straight off and clean the area with mild detergent.
  • Check fascia alignment: Ensure the control panel is not bent or pressing against knob skirts.
  • Valve condition: If stiffness persists, the gas valves may need professional servicing or replacement.

Do not force knobs; this can crack the valve body and cause gas leaks.
