Why This Knob Breaks

Weber's factory control knobs sit directly above the burners and in full sun, so the plastic cracks and fades after a few seasons of UV and radiant heat exposure. Once a knob cracks it stops gripping the valve stem cleanly and gets hard to turn — which is why Weber and third-party sellers sell replacement knobs individually rather than as part of a full valve assembly.
