First, let me explain the 1-star, as it was a 4-star for the first 8 years we had this model. (The dim interior light was annoying.) We purchased this microwave in 2016, and the magnetron recently bellied up. Everything else works except it doesn't heat food anymore. At first we discussed repair vs. replace, but now we've decided to replace it with a good range hood like we had before and go back to a small or midsize countertop oven of some kind.  If you're wondering why, its because even though it was vented, the fan was not as strong as the old range hood, so it didn't take much to set the smoke detector off.  Also, the surrounding cabinets have required lots more cleaning to stay on top of the accumulating cooking grease. I would have liked to have known about these 2 cons to consider before purchasing this style microwave.
