My oven will not heat since I ran a routine cleaning. I observed no problems during the clean mode. It completed its cleaning and looked great. But when I went to use it the next day both of the heating elements will not come on. Everything seems to be working fine on the controls, IE time, sllect temp UP/DN, broil, bake, etc. Is there an simple fix like reset button / fuse or some kind of diagnostic to find the problem?
