I had problems sometime ago with the oven light going out after a few minutes and haven't used it for about 3 months. I pluged into the AC and immediately blew the fuse.
Having the same problem with a R2001C. I can unplug the primary transformer from the power supply board and no longer blows fuse. I do not have a service manual for this unit.
