Diagnosis
The broil element has failed. Arcing caused the spark and crack. This is a direct replacement.
How to Fix It
Unplug range. Element is held by two screws at the back of the oven cavity. Remove screws. Gently pull element forward. Disconnect wires from terminals. Attach wires to new element. Part is usually W10307441. Push element back, secure screws.
If That Didn't Work
If new element fails quickly, check the socket terminals on the oven back wall. Burnt or loose terminals cause arcing and kill new elements.
Heads Up
Element terminals are live when plugged in. Always unplug first. Ensure wires are fully seated on the new element's terminals. A loose connection will repeat the problem.
