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

Safety first: Turn off gas supply if removing valves. Ensure the appliance is cool.

Steps:

• Clean spindles: Remove knobs and clean around the valve spindles with a degreaser. Do not allow liquid into the valve body.
• Inspect knobs: Check the knob sockets for cracks or rounding. Replace worn knobs.
• Valve condition: If a valve is stiff or seized, it may need lubrication with a gas-rated grease or replacement by a professional.
• Check fascia alignment: Ensure the front panel is not pressing against the knobs, causing binding.

Warning: Do not disassemble gas valves yourself; improper reassembly can cause leaks.
