I have a Quad Mt Vernon AE about two years old, has always run well, this is the third Winter for it. Today I tried starting it up, after a little while it shut down and game me the reading - "Conv Blower Jammed". Of course, now that I have opened it and found nothing unplugged or otherwise obvious or simple to fix, I will call svc rep tomorrow, but would like to hear of anyone else's experience or thoughts on subject. The convection fan rotates freely, but just doesn't seem to get any juice.
