Our Whirlpool Oven slide in model was not working, as the oven was not heating up. It is six years old, and cost over $1800. at the time. I did not want to be looking at getting a new stove, as we had just replaced our dishwasher a few months ago. I called North Durham Appliance, and spoke to Kevin. He mentioned it was possibly the baking element, and would order the part, and have someone come out check, and replace. Technician Lucas came out on time. Checked the oven, and sure enough it was the baking element. He also checked the stove over during this time. Approximately half an hour to complete. I am very impressed to say the least. Lucas was very professional, and explained all of our questions to our satisfaction. Definitely would recommend them.
