Questions about this item

Which Weber Genesis models accept the sear-knob assembly with part number 40255403?

The knob fits 21 Genesis models including 6639099, 6631701, 6631001, 6532301, 86531001, 86570001, 6570001, E-330, 86531701, 86531301, 6531001, 6631301, 86631001, 86670001, 6531301, 6532001, 86631701, 86631301, 6670001, 6537001 and 6531701.

Will the light-gray sear knob match the existing control panel on an older Genesis grill?

The part is coloured light gray and is designated for Genesis DOM 11 grills, so it will match the original panel on those models.

How can I confirm the new sear knob is operating correctly after installation?

Turn the knob to the sear position; the burner should ignite and reach high heat for searing, and the knob should feel firm without wobble.
