I googled the model number of our combo oven-microwave, and AppliancePartsPros popped right up. One of the first things I saw was the instructional videos for each part -- and that definitely sold me on ordering from them.
I ordered all three parts and they shipped immediately and arrived before their estimated date. The window glass went great -- the video was dead on, and I had it fixed in short order. The broiler element was easy, too, and the tip for ensuring the wires don't slip back behind the oven wall was great. I can't believe how hard the manufacturer makes it change a stupid lightbulb. The video was instrumental in explaining how to get to it. Unfortunately, as I was trying to get it in place, a pin broke off the lightbulb, and now I'm waiting for a replacement to arrive. My fault.
