THERMOSTAT MAGNETRON WB27X10567

First I ordered and replaced the diode. That did not help. Then I ordered both the magnetron and the thermostat magnetron because I didn't know what I was doing. After I replaced those, it still wouldn't heat. So I called an electrician. He noticed I had knocked a wire loose. I connected it and the microwave worked. I reconnected the old magnetron, just to test it. It didn't work. Then I put the new one back in. It's working just fine now! It took quite a while to put everything back in place because it was a built-in. But it was a lot cheaper than getting a new microwave, even with the cost of a repair man to show me I had a loose wire!

First step was to discharge the transformer's capacitor (very important to do), before attempting any microwave repair. I opened the diagram/schematic found inside the microwave oven and followed the technician's troubleshooting steps; checked the capacitor; it checked OK, I checked the diode for a short, it checked OK. I checked the windings of the transformer that supply the power to the Magnetron; it checked Ok. I proceeded to order the parts; the Magnetron and the sensor located on the top part of the Magnetron. When the parts arrived; I went straight to the location of the Magnetron, I attached the new sensor on the new Magnetron and removed the old one. I connected the harness from the transformer to the new Magnetron and tested the microwave oven and it worked perfectly like a new one. This site has a great deal of information about repairs for the do it-yourself like myself, unlike other appliance's parts websites. Thumbs up to this site, I am very pleased with my order, I received it in a timely fashion as promised. I recommend it to everyone; this site is the best place to shop for appliances parts.
