Bake and Broil not working. Hello I have a Kenmore Gas stove that came with my house but no

Question

Hello I have a Kenmore Gas stove that came with my house but no manuals. The model number inside the bottom drawer of the stove says 911.7359180 Serial number OM203003Q.Yesterday I was going to bake and I touched the bake button and the display just flashed bake--- and never light or displayed a temp. I then tried the broil button with no luck. All my top burners are lighing fine. What could the issue be.

My Kenmore builtin range Model #911.3012992 stopped the day before Thanksgiving. Then it worked on Thanksgiving morning and and hasn't worked since
