Is it Worth Trying to Repair a Bread Machine?I got this old bread machine Regal Pro Breadmaker K6773. It works when I plug it in, but when I try to set a mode or do anything else, I get this E 07 Error, which, according to the manual, is a "possible circuitry defect". Is there any way to find out what exactly is wrong with it or, more importantly, is there any way to fix it?
