Jack for Model Number ACM2160AB Have had several incidents where we had arcing from behind the protective cover/shield [on wall inside cavity] for the magnetron accompanied by loud hum and popping sound. This happened several times in the past year, but would always operate properly once again after being turned off and restarted. However, now, unit continues to arc and even burn the protective cover/shield. I suspect that I need a new magnetron unit...........or could it be something else?
