This genuine silver painted control knob assembly, part 140175221054, comes from the Electrolux group range of knobs used on Westinghouse cooktops. Electrolux also lists it as A17522105. Its stock description marks it as the SC silver painted version, and several close relatives in the same number series differ by finish and cooktop type, so match the number on your old knob or parts list before ordering.

Cooktop knob slipping or worn?

A cooktop knob grips the shaft of the gas valve or energy regulator so you can set the heat accurately. With daily use, heat and cleaning products, the socket inside can split or wear smooth, and the knob starts slipping on the shaft, wobbling or pulling off. On painted silver knobs the finish can also wear through or flake, which makes the markings hard to read. A slipping knob is more than a cosmetic problem, especially on a gas cooktop, as it makes it harder to tell when a burner is fully off.

Swapping the cooktop knob

Check every burner or zone is off and the cooktop is cool. Pull the old knob straight up off its shaft and wipe the shaft clean. Line up the flat inside the new knob with the flat on the shaft, then push it down until it sits evenly against the panel. Turn it through its range and back to off to confirm it moves smoothly.

Questions about this part

How many knobs should I order?

Order one for each knob you're replacing. Many people replace the full set so the finish matches across the cooktop, as older painted knobs fade. Check that every position on your cooktop uses 140175221054 first, as some cooktops mix knob types.
