When I turn on the oven it used to start in Bake at 375. Now it starts in broil at 500 and the bake option won’t work.\
Any ideas? This is a Whirlpool electronic controlled oven.
when turning on oven i push bake but only broil lights up, if i slam door shut a half dozen times it sometimes lets me bake. also, everytime i’ve self cleaned oven since bought new the thermal fuse has blown. whirlpool rbs305pdq6, bought in 1999. suggestions?
My suggestion is to find a deep hole and drop it in. 
I’ve worked on a couple of these in the past. I would describe them as a poor design. That whole thermal fuse thing is a really bad joke. It sounds like yours has been a pain in your rear for a long time. It also sounds like your electronic control is failing. I’d bet $100 its not available 17 years after manufacture.
