Make/Model: Whirlpool Oven RBD305PDB12. After reviewing the other repair stories here I took a chance that it could have been the main control panel circuit board as it was the last time this happened to me. Had that diagnosed and it was ok. Pulled the whole oven out of the wall and found that the upper oven thermal fuse had blown. Quick fix after getting the part. Part came quick so not much down time on the oven. I did find my fuse behind the upper oven and not the lower as depicted in other reviews. Tools required: Phillips head screwdriver, ohm meter, & muscle. Don't forget to turn the power off!
