James W Round Hill , VA April 15, 2017 Appliance: Jenn-Air Electric Wall Oven WW27210B Jenn-Air Oven Ww27210b: Element burned out. How to replace Bake Element (Lower Oven). It only takes a screwdriver for this repair. Remove the two screws holding the old element, pull it out of the housing, making sure the wires attached to the element do not fall back into the housing when you unclip them. Once you reattach the wires, simply replace the two screws and the job is done. I could not reuse the old screws though since the old ones did not hold the tight (unit is 20 years old and they were simply stripped). I simply increased the thickness of the screws and the new ones fit better. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
