Question about Microwave Ovens
That is probably a blown control board or a blown wiring harness. The oven must be taken apart, testing impedance on power cord and wiring harness, and finally replacing the control assembly if the cord is not faulty.
The wiring is tested with power off. The disassembled microwave cannot be turned on to read volts without disconnecting the magnetron first.
For this reason the testing is done reading Ohms rather than volts at control assembly connector.
Testing must be done by a technician. The oven must be tested for energy leakage after the repair.

Hi - From what you have described it sounds like the microwave possibly has a wiring failure or faulty control panel or magnetron. I would suggest contacting a professional that accurately diagnose and repair the unit
