[QUOTE="Denny D, post: 98709, member: 11274"]The Channel Master 9521A is manufactured in lots of thousands and shipped to the USA. Each lot had a different problem. One problem may be solved but another would arise. Most of the issues with the Channel Master 9521A started when the manufacturing was moved from the USA to China. I'll try to recall what all of the issue were. The first lot (boatload) the outdoor motor would get stuck in what I call the "North stop". The motor would run fine. However, when it would hit the 360 degree stopping position it would simply stop and not start up again. It would be stuck in this position and the motor would just hum. The next batch that came in had the "North stop" problem mentioned above solved but the mast motor on these units would simply quit working in any position. The winding wire used on the motor was too small of gauge and would burn up (fry) when in use. Almost forgot the ball bearings.
