W10828837 is a Whirlpool part used across KitchenAid ranges (cross-referenced as AP5988577). Like most Whirlpool-family knobs it cracks at the D-bore; a printed PETG replacement puts more material exactly there.
Shaft fit: 6mm D-shaft class (Whirlpool-family ranges) — confirm your stem before ordering. 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.
