How do I troubleshoot a Walthers 130' turntable? - Model Railroader Magazine

Well, so much for a thorough cleaning. I had begun to convince myself that cleaning would solve the problem. Meanwhile, Walthers Tech Support is not being responsive.

I did some further research on the ERR1 issue, and it seems to suggest that the controller is the problem. The solution in a couple of cases was to replace the controller. The replacement controller for the 933-2859 is the 933-2320. It retails at Walthers for $49.98, but you can find it discounted for about $40.00. That may be the way to go.
