Barry B Marcellus , NY March 15, 2016 Appliance: Jenn-Air Self Cleaning Slide-In Downdraft Electric Range S120-C Jenn-Air Range S120-C: The lower oven heating element burned out. How to replace Range Bake Heating Element. I removed the old element (turning off the power first) and installed the new element which was a perfect match. I had ordered the new part on Thursday night and even with normal shipping, had the new element on Saturday afternoon. The oven was up and running less than 15 minutes later.
