I had a GE Spacemaker Microwave, model number JVM1430, in my old home in Cedar Hill. They gave me a black one to save themselves money. I thought I had a pretty good deal, aside from having a microwave which wasn't the color I wanted. However, the magnetron went bad after we had only been living in the house for a short time. Fortunately, the house had a full ten year warranty, so Choice Homes replaced the microwave oven with a brand new one.
Well, what do you know, but the new GE Spacemaker microwave oven developed the same problem. I complained furiously to Choice Homes, demanding they replace the oven. The repair people came out and replaced the magnetron, and said that the problem was caused by a bad supplier who was providing faulty parts for the ovens. They stated that the supplier had been replaced, and the problem with the bad magnetrons had been solved.
The oven worked fine for the rest of the time we lived in the house, so when we moved to a fixer-up foreclosure, I had no problem with buying the same model GE Spacemaker microwave oven. The $350 price included professional installation. I finally got my white Spacemaker microwave oven, but this time I had a slightly different model. I liked the features; it has a popcorn button, a beverage button and express cook buttons which allow you to cook by pressing only a single button once. However, the new model required that I press the beverage button twice to heat eight ounces of water, which I didn't like. I use large mugs anyway, so I usually just press the express cook 2 button to heat the liquid for a full two minutes. It works great for heating liquid for tea, hot chocolate and coffee.
However, just the other day I had the magnetron on this microwave go bad, just like on the two I had in my previous home. I didn't have an extended warranty, so I ended up shelling out $189 to GE for in-home service.
My advice is that if you purchase any microwave oven, regardless of brand name or model, get the longest extended warranty the store will sell you. These days appliance manufacturers are simply too many cutting costs, and the customers are paying the price. So be sure to protect yourself fully, and you will come out on top every time.
