How to Fix / Troubleshooting
Safety first: Turn off gas and power before removing knobs or working near valves.
- Remove knobs: Pull the knobs straight off the shafts. Clean the knobs and surrounding panel area with mild detergent.
- Inspect stems: Check valve stems for signs of melting or bending. Replace damaged knobs.
- Do not oil gas valves externally: Do not apply household oils directly into gas valves; this can damage seals.
- Professional service: If valves remain stiff, a technician should service or replace the gas valves, applying the correct high-temperature lubricant internally.
