How hard or complicated is to change the Magnetron (Part # AP3109455) Manuf Part # 4392007? Is the part rarely accessible to get to?
Answer Hi. Remove the back cover. You will need a security type torx- t 15 or t 20 size tip on one back screw to start. Then it is on the rt. side of the inner cavity mounted by 4- top nuts. The magnetron part # 4392007 is close to the high voltage capacitor that stores lethal voltage. So be care full. The diode part # 4313101 is usually changed as well if it does test shorted (ohms both ways) or open (no continuity). Pay close attn. to wire connections for tight and correct application. Thank you.
