Installed new lower heating element. 4 screws, but I could have done it with just two.
You can remove the old element from inside with just the 2 mounting screws, but I went in the back so I would not have to pull the wiring through the insulation. Straight forward repair. It took longer to clean the area behind the oven of accumulated junk than to replace the heating element.
Fast delivery of the part from Appliancepartspro.com . Will use them again in the future.
