One of the two fans died on my z-42 this morning. I turned the fans on like I usually do and I heard a buzzing coming from the right one. The left spun up fine. I cleaned them as best I could, but I still can't get the one to work. My questions are: 1. Is there something I can do to fix this without replacement? 2. Can I use an aftermarket fan kit for this? The z-42 kit is kind of pricey, and hard to order since there's only one shop that carries it in NH. Thanks!
