Mack R Kingston , WA February 23, 2015 Magnatron burned out Replacing the magnatron was a simple process. I learned 2 very important things. 1. The risk of deadly shock is real. Know what you're doing. 2. Do your research on why the Magnatron burned out in the first place. Look to see if your "stirrer" is rotating as it should. If it doesn't have one then you may need to replace the silver "card" located on the inside of the microwave just in front of Magnatron. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
