Wolf replacement knobs are famously expensive — individual knobs run $74–$100 and full red-knob kits reach $440. If yours cracked, a custom-printed knob (in Wolf red, black, or stainless-look gray) costs about $20 shipped. Check your shaft size with the knob pulled off, then match the bore exactly.
Shaft fit: Verify your shaft: pull a knob and check — most ranges use a 6mm or 8mm D-shaft. Knobulator lets you set the exact bore
shape and clearance, so the knob grips the shaft instead of spinning — the usual failure of
one-size-fits-all replacements.
