Microwave Magnetron (replaces WB27X10475) WB27X10017

GE Profile Microwave not heating, faulty magnetron

GE Profile Spacesaver microwave would not heat and produced electrical odor. I replaced the capacitor and diode initially (easy to install) which eliminated the odor, but still would not heat. When magnetron was removed, I noticed a burnt spot on top which was an indication of a failure. After magnetron was replaced, microwave worked as expected. Replacing the magnetron was somewhat cumbersome in the GE Spacesaver as it has a plastic housing in which the magnetron must fit into. This made it difficult to install and align the new unit. With some effort it eventually went into place. Overall it was not a difficult job.

Installation

Depending on a persons knowledge of mechanics, I have a good basic knowledge of how mechanis work. Once I determined how to remove the magnetron I just had to reassemble it in reverse. Make notes and take pics with your phone as you disassemble. For me, it was more difficult to diagnose the problem than to install the part. OH! and when working on a microwave be sure to discharge your capacitor it can hurt if you happen to short it across your hand or finger.

Reasonably easy to install

I have GE microwave mounted on the wall over the stove.The microwave weight is about 60lb, needed a second person to dismount it. Found instructional video on Youtube on magnetron replacement in a similar unit. Some details were different, it took time to figure out. Overall the job of magnetron replacement took just over one hour.
