The chat lady found the parts I needed for my 36 year old oven in about 2 minutes. The parts arrived the day after my order even with standard shipping. The video showed me how easy it was to change the burners and had a great hint as to how one keeps the wires from slipping back inside the oven. I did need to use more tools than the video man used but in the past I have rebuilt an automobile engine so this was not a problem for me.
