Micro-malfunction

Our microwave oven recently went on the fritz, which opened the door for me to pursue some home improvement in the last months of our stay at this house. I'm not sure what was wrong with it, but the bright flash and smoke smell were definite indicators of a Situation NG diagnosis. So, we decided instead of trying to fix it we could buy and install a new one for about the same amount. After doing our requisite internet research and checking a few different local retailers, we finally found a replacement at a great price (Em had a "feeling" about going by Sears....don't ever doubt the power of female intuition). In the process of removing the old unit and installing the new one (pictured above), I learned a lot about over-the-range microwaves. For example, did you know that there are three different kinds of exhaust options on microwaves.....fascinating stuff, I know!
