This is just the nature of electronic controls. One signal line is as

I tried to find a replacement oven with no electronics and had no
luck. My old Whirlpool with mechanical controls lasted almost 40 years
but the can inside finally rusted out.
It was still working fine tho.


I wonder how many appliances are scrapped for minor electronics
problems. Some 20 cent diode fails and a $400 board is needed for the
fix.

We often had a microwave in the shop that someone wanted us to fix. It
was almost always the board and the board usually cost more than a new
microwave if you could find one. I did take a big "cook a turkey" size
Amana microwave, drill a hole through the operator panel and put in a
spring wound timer. I made sure all of the interlocks still worked and
we used it for years.
