The number keypad on my microwave is failing. Is there possibly a fix, other than replacing the entire control panel?

I’m thinking not, but I thought it wouldn’t hurt to ask.

All the other buttons work fine, as does the microwave itself, including the carousel, display, etc., but, the numbers 6, 7 and 9 on the keypad don’t work at all, and the 1 works, or doesn’t, erratically. That leaves me with the 2 ,3 ,4 ,5 and 8.

When the 1 isn’t working, if I want to cook anything that requires more than 10 minutes, but less than 20, the closest I can get, without going over, is 8 minutes, 58 seconds, then I would have to cook it for any additional time it might need; something that needs to cook for 14 minutes, e.g, without a functioning 7, I would cook for 6 minutes, 58 seconds, twice, just because the math is easier.

Anyway, you get the idea.

I am really reluctant to replace it, because I don’t use it all that much and there’s kind of a work around. It is kind of frustrating though. I am handy enough that I think I could replace the control panel myself, but I can’t find the part.

Would repairing this problem actually require a complete replacement of the control panel, if I could find the part?

Is there anything else I can do?
