Control knobs on Avanti range are hard to turn or feel loose

Safety first: Turn off burners and allow them to cool. For gas valves, do not spray cleaners directly into valve stems.

• Remove knobs: Pull knobs straight off the shafts.
• Clean area: Wipe grease and debris from around the shafts and panel with a mild cleaner on a cloth.
• Inspect knobs: Check for cracks or stripped inserts. Replace damaged control knobs.
• Valve/switch condition: If knobs remain stiff or wobbly after cleaning and knob replacement, the underlying gas valve or infinite switch may be worn and should be replaced.
