I have a microwave oven which timer button is broken. I would like to fix it (by using glue?) or replace it (with a similar "key"). The oven is a Samsung M1714.

However, I am afraid of making things worse if I try to repair it, and I do not know any shop where I could buy something similar. I noticed there is the number 3 written on the inside of the broken piece.

Looking at the oven, with and without the button Looking at the connection on both sides

Do you know an online shop for this kind of thing?

Here are several shots: Looking at the place where there should be a button Looking at the button side which is usually not visible

I have repaired dials similar to this in the past.

I have found that if you apply some CA glue (super glue) or epoxy to the crack, and then wrap the outside of the shaft tightly with electrical tape, it will hold up under most circumstances.

Failing that, it appears that you can buy the replacement knob from several online suppliers.

    A small metal hose clamp may work after using glue . But seriously, get a new knob, that one looks like it is toast!!!!!!!! Commented Feb 17, 2011 at 0:22
  • Up-voted this answer because of the hose-clamp idea in the comment above - exactly what I was thinking.

You can actually repair this knob with resin + fiberglas. You can see the final result here.
