Cooktop knob spinning or falling off?

A cooktop knob turns the gas valve or hotplate control beneath the panel. On gas cooktops it's usually pushed in and turned to light the burner, so the knob takes a lot of force over its life. The insert that grips the shaft can split or wear round, letting the knob spin without moving the valve. Other common problems are knobs that wobble, sit crooked or have their markings worn away by cleaning. A knob that won't grip properly makes it hard to set the flame and isn't safe, so replace it rather than reaching for pliers.

Fitting the knob

Check every burner is off and the cooktop is cool, and turn the gas off at the isolation valve before working at the controls. Pull the old knob straight up. Some knobs have a small spring clip inside, so make sure it stays in place. Align the new knob with the flat on the shaft, push it down firmly, then turn the gas back on and check the burner lights and shuts off cleanly.
