** Kenmore [range model 911.92481991]. I did the self clean and now the oven won't let me cook in it. Every time now, the cleaning button flashes and the oven won't turn on. **
There may be a problem with the door latching mechanism, its switches or the wiring to/from it. If the control 'thinks' the door is still locked it might act as if it was still in cleaning mode and not let regular oven functions operate. Most likely someone will need to open up the range and inspect it.
You can see the door latching mechanism used on your model at the following link:
