This is a simple repair that anyone can do. Cut off breaker or unplug your oven first, remove racks, locate the screws that are on the bracket that holds your element and remove. Unpack your new element and lay it next to your old one, gently pull out your element so that wires don't pull off, when your able to see the wires remove and replace them on new element one. Remove the old element out of your way and install screws back into your new element after pushing back in place gently. Plug back in your oven or cut breaker back on. Turn on your oven and element should get warm rapidly.
