There is so much stupid here I don't know where to start.
First off, a modern day child's ez-bake oven probally is more effcient and cooks quicker then a 30 year old microwave.
I just seen a brand new above the range Kenmore for $100 at a moving sale...they had the recipet and just bought it six months prior for $190.
I found the best place for a microwave is on top of the refirgerator if you need space. The under the cabinet ones sometimes are not that good and pricey. I also agree that some of the less expensive models are just as good as the others...they are all made by the same seven year olds in China.
The only thing worth checking if a microwave fails is the fuse under the cabinet of it. It simply looks like an automobile fuse and it near the power cord connection. Why pay a repairman to burn that expensive gas to try and visit your house and look at it?
I'm sure the only appliance repair company that DU uses has a fleet of smart cars...my bad.
