Recently, our microwave stopped working. It was making a horrid noise, and not heating anything. I learned to work around it, and for the most part didn't think it would be needed. Chris vetoed my philosophical ideas of life without a microwave immediately! ha! So the choices were to replace it or fix it. GE no longer manufactures this particular model, and I soon learned that it averaged about 1 out of 5 star ratings on almost every review I read, most indicating that it broke soon and was expensive to get repaired. So then we researched buying a new model, but I would have had to cut new holes in the cabinets and install a new mounting bracket (this monster is above our stove top) which sounded like more frustration than it was worth.
So, repair it ourselves won. Chris helped me - I thought I was going to do it alone, but I suspect he thought I would electrocute myself (not to worry, I did everything safely). It was good to have him help, because that machine is HEAVY! So we fixed it within a few hours, and only ended up with one leftover screw when we were done, which isn't great but I wasn't about to take it apart again and figure out where it belongs. One new magnetron and diode later, it works like brand new!
On to the sump pump - which has the potential to be even more frustrating and gross than the microwave!
