Samsung OM75P(10)ESGN Assembly OEM Part

I took the microwave apart and visually inspected it, which yielded nothing. I discharged the capacitor with insulated screwdrivers and needle nose pliers. I then unplugged the wires to all the larger components. My microwave had a schematic diagram inside the case so I was able to test with my multimeter all the individual parts against the expected results. I tested the transformer, magnetron, capacitor, and the diode. All parts passed which left me a little discouraged. I removed the magnetron for a closer visual inspection. On inspection I found a hairline crack in the top magnet. My theory was that under electrical load, that crack expanded, which would explain the failure to create heat (and the favorable multimeter tests when cool). I decided to replace the magnetron. I did the diode too since it is only a couple bucks and I already had the case open. I was unable to find the original OM75P10ESGN magnetron so I purchased the substitution, OM75P10ESHL. I put the new magnetron and diode in, cleaned and reassembled all the case pieces, and tested with a glass of water. Water was hot… success!

Took the cover off and noticed a spot that looked burned. From the side I could see some "thing" underneath. Figured it was some kind of Flux Capacitor. Pulled it out and googled the part number and discovered it was actually a Magnetron. Saw a picture of a new one that looked nothing like the fried, burned one I had, found the part on this site, appliancepartspros.com and the price was the best I could find so I bought it. It arrived the next day! I had taken the the Microwave out to the garage and the wife thought I was throwing it away. She was researching the price on a new one - over $500 - while I replaced the bad part. $65. Next day she came home and I had reinstalled the Microwave above the range. Boiled a glass of water and I got a hug and a peck on the cheek. I was hoping for a little more, but after 27 years of marriage, I'll take what i can get.

I had to remove the microwave from the range and then remove the cover from the microwave to determine the exact problem. After a visual inspection then discharging the high voltage capacitor, I used a meter to test the high voltage diode and fuses. After using the meter to ohm out the magnetron, I removed it from the unit, and seeing that the hole in the end of the magnetron's tube was enlarged and burnt, as if it was arcing, I assumed it was the bad part. I ordered the parts from Appliance Parts Pros and replaced them in the unit. It works like new.

I had a idea it was the magantron .when it was on the cook cycle it made a loud Hume . I open the cabinet made sure the capsator was discharged and removed the magantron .when out observed end was burned out . Look online found the one I needed ,installed it and put the oven back in service.

Replaced the HV diode first then the Magnetron. Advice: check multiple sources to learn OEM part numbers and search/shop based the OEM part numbers. Had I purchased the exact GE part numbers I would have spent $35+ on a $5 Diode and $150 on a $75 Magnetron. I must add I have a background in electronics and mechanics and as a DYI'er was confident in my cross reference knowledge and part selection. If you don't have the experience to know the difference a call into support before purchasing parts is advised. Bottom line: our 2007 $800 GE Profile over the range microwave is now fixed for less than $100 bucks and we did it ourselves thanks to diagrams provided and our DYI background knowledge thank you very much APP.
