I have a sumsung microwave model SMH9207ST that has no power. So far this is what I have checked and done to try and fix the unit. Checked all fusible links they are all good. Checked switches on door they are all good. Checked fuses they are good. Confirmed with volt meter that I have 120 volts going to the power control board. Ordered at different times the Power control boards, PCB MAIN;RAS-ML9M-0 Part Number: DE92-02135A and PCB MAIN;RAS-ML9P-0 Part Number: DE92-02136A neither corrected the problem.

Any ideas before I give up

Wire harnesses can cause power losses like this also not sure if your doing this with the microwave Uninstalled or not but sometimes there is a hidden cavity fuse or thermostat attached somewheRe to the top or side of the microwave cavity that blows and will cause a "dead" Microwave
