For a refrigerator knob B fix if lost use a ball point pen cap or cut the
housing to length. Just slice the end that fits over the interior button
about 1/2 inch with a hacksaw to allow it to fit with a little pressure.
Anyone needing a photo pmail me.

Mine was lost but found when I pulled the refrigerator for servicing and
cleaning. I found the knob sitting on top of the fridge where the previous
owner must have lost it. Once I saw how it looked it was easy to see how a
ball point pen cap cut to allow it to fit will work.
