KitchenAid Double in-wall oven. Secured power. Removed 2 screws securing element to oven roof and 2 screws securing element to rear wall. Carefully removed broken element and secured 4 wires with twisty-ties. Detached wires, making sure they did not slip back into back wall opening. Attached wires to new element and pushed it and heat shield back into place. UNFORTUNATELY, one of the wires became detached. Next call was to a local expert with a special double-oven dolly. We removed the oven doors and then secured the element/shield into place. We removed the unit, replaced all 4 end connections and found one unrelated defective connection and replaced that. Re-installed. The CAN be an easy task but my advice: Call the expert FIRST!
