One of the great wastes in society is microwave ovens that suddenly stop working and get thrown away, when they could have been easily repaired. Most times, all that's needed is a new fuse, bought for $5 at the local hardware store. (First make sure that it isn't one of your house fuses that was tripped.) Over the past two weeks, I've saved two microwaves by inserting a new fuse. If you like fixing things, or know someone who does, this is a great way to save a good appliance.
