    Read the number off your old part

    Look for the number stamped or printed on the part itself. If it says W11578570, or the older number listed under Compatible parts below, this is the replacement. Every one of them is discontinued and every one leads here.

    Shipping box

    Weight and size of the parcel as it ships: 0.10 lb · 2.2047, 1.2992, 0.8267 in. These are the carton, not the part — do not measure your old part against them.
