Bake element burnt out

Before you touch anything unplug the range or trip the breaker. Pull the racks out of the oven, it gives more room to work. Remove the two screws that hold the element and pull the element out about 2-3". Disconnect the old element. Before you install the new element check the wire and the connectors for age and heat damage. If the connectors are loose replace them (2 connectors @ $1.97 is better than a short in the oven). If the insulation on the wire is degraded (brittle, flaking, brown) consider changing out the wiring. This means opening up the back of the oven and that is another chapter. In most cases you can just re-connect to the replacement element and attach it back to the oven with the two screws. I ran the oven to 400 degrees to just check that everything was OK. Spent a couple extra minutes to check everything out and save yourself pain later.
