I have a fan in my MicroVAX II which sometimes does not start without a push, which means that I can't really put the machine back in its external enclosure. I have been unable to find an illustrated parts breakdown to give me a part number for the fan, so I was wondering if anyone here knows the part number, or has a suggestion for how to get the fan to work properly again. The machine is in a BA23 enclosure and it is the front fan which does not work well. Thanks Rob
