have a KitchenAid electric oven with microwave combo. From time to time the oven will have 2 (related I think) problems. In one case the oven does not shut off and stays heated despite it "accepting" the request to shut off when we hit the Cancel Oven button (and hear an acknowledgement tone). The other problem is that sometimes after using the oven and it shutting off it will heat up on its own. This also occurs at times after we have shut off the circuit and turn it back on the next day (or sometimes days later).
The model number is: KEMS307GWH0
The serial number is: XJ1501022
I am somewhat handy and would prefer to try to fix it myself. No help and no support from KitchenAid. They pretend there is no problem out there despite I see similar complaints out there on the internet.
Thanks in advance for suggestions.
Other info that may be helpful. The oven does respond to the Cancel button being pressed by making a sound. When it turns on by itself it seems to settle in on a temp around 250…it does not heat up to a high temp. I have tried to hit a temp of 000 and start as well as 000 and Cancel as others have suggested. No help. We have to turn it off at the circuit. Also, this is a model that has a convection feature. We notice that it is even more problematic that this thing won’t shut off if using Convection (rather than the normal Bake mode).
