Ive got a kenmore gas wall oven it has an f 11 that won't go away sears won't help without a work order and I don't feel like paying lots of money to find out I bought a piece of junk.

I don't know if this might help, but I found the following "somewhere on the web":

try this... turn off power to the oven. Remove the cover of the electronic keypad (there are four screws at the top and two underneath the cover). Pull the cover forward and there will be a tech instruction sheet inside the compartment.
This sheet should have a list of the error codes in it. That might be a clue as to what is wrong.

Best of Luck,
