Er...How did I fix it? Perfectly actually! Easy even for my 66 year old lady self. Here's the rub: You have the racks out. You have the element out. Seems like the perfect time to finally clean it. Ugh...obviously I'd rather fix them than clean them.
Replacing the element...15 min total including putting tools away. Add an hour for oven scrubbing.
Also...super fast delivery. This is the 3rd old appliance I've repaired and all the parts and advice came form this site. Highly recommended.
