Top element wasn't working on ~1.5 year old oven

FIgured it was either a bad heating element or a realy expensive repair so I purchased a replacement element to rule out the simple and inexpensive possibility. Pulled oven out from wall and disconnected power supply. Removed retaining bracket from top of oven, two screws that held in heating element, disconnected from fittings, replaced with new element, and reattached screws and retaining bracket. Plugged in power supply, tested lower oven (it worked just fine) pushed oven back against the wall. Threw away the old element and packaging. Job done.
