Have Amana RL6-10ET microwave–interior light works, transformers, capacitor, diode, fuse, etc. seem OK. Control panel lights; clock seems to set and work. I’'m sure magnetron, high voltage, etc, OK, but No action from control panel(-except interior light.) No mode stirrer, platter, heat, etc. I’m sure it’s C.P. or TRIAC or something, but have no user manual, so need to know how to correctly turn on at about half power a few minutes to troubleshoot.
