The oven went pooof and stinky black smoke came out when trying to use self cleaning...Now wont heat at all. electronics work fine.

Hi. The model number you gave me is for a microwave. It sounds like you are referring to an oven. IF your broil still works, then I suspect that your bake element went out. Usually when this happens you can see that the element is broken in half at some point or has a melted silver spot or hole on it. IF your broil is not working as well I would check your control board. You should see a burnt spot on it as well as it will smell like it has burnt. IF this is the case you will need to replace your control board. I have attached a video that shows a bake element repair. IF you need any further help please let me know and attach the model number for you oven.
