Hi I have this issue for a whirlpool h53521hz over-the-range. Problem started literally “overnight” as in I woke up to it closed per normal but the slight sound of the internal vent could be heard and the light was on. When I open the door it would turn the fan off.
Here’s the catch: I read about ten of these kinds of forums and I bought perfect replicas for ALL THREE switches and did a full swap. Much to my dismay, as soon as I closed the door, it did the same thing! I know I couldn’t have installed them incorrectly or it wouldn’t be doing it (or working at all). What else could need to be replaced? Are my other options going to “total” my microwave, meaning it will be cheaper or easier to just buy a new model?
Thanks!
