How do test the magnetron part number ap3994054 to see if it is bad?
ANSWER Hi David. You Will use an ohm meter and put it on Rx1 scale. Short together the leads and make sure the ohm out less than 1 ohm. Then put one lead to the magnetron chassis, and one lead to the terminal on the magnetron. It should read open (not shorted)as it will be good. Test both terminals to insure that they are not shorted to ground. Your magnetron is part # WB27X10927. Thank you.
