Ge WB27X11033 Capacitor High Voltage OEM Part

I took the advice of another buyer and replaced the magnetron, capacitor, and diode from my microwave (make sure you discharge the capacitor). It was not a problem at all to do, I did find an excellent video on YouTube on how to test all of these components and almost anything else in a microwave. It’s called Microwave Oven Troubleshooting in Minutes- Step by Step by electronicsNmore. It was the best thing I watched. Turns out my magnetron was the only thing that was bad and it’s the most expensive part, so replacing the other too wasn’t a big deal. My microwave really heats well now. I guess it had been getting bad for a while. I might get add, my microwave was a $1500 GE MONOGRAM microwave/convection oven so spending a couple hundred for parts was a no-brainer, but had it been a cheaper $300-400 model, I would’ve just bought another one. Matching the appliances in my wife’s kitchen was also key. I might also say, that although I’m handy and do have some electronics experience, I built my own tube guitar amps years ago, I am a counselor by trade, and doing this project taught me how a microwave works. It was fun to learn, and easy to do. Watch the YouTube video before you remove one screw. You will learn a lot, and also see a professional be extremely careful while discharging the capacitor. 1000 volts is nothing to play around with, but the capacitor does have a discharge resistor built-in and mine was discharged when I tested it, and although the video shows you how to build a discharge rig using a ceramic resistor, which is the safest way to go, I don’t personally think it’s necessary. He shows other ways to discharge too. This is the most important thing to do in this repair.

Instead of wasting time troubleshooting, I purchased the 3 components suggested that could be the cause for the issue (magnetron, diode and capacitor). Replaced all 3 components and now I once again I have heat. Job was really easy except for trying to install the screws around the magnetron - kept getting sucked up by the magnet. Great website and parts arrived as quickly as advertised.

Bought some fuses and found step by step instructions on internet to narrow problem down. Mine said diode but bought capacitor just in case. Drained charge on capacitor and replaced both. Working fine now. Finding problem took about hour fixing about 10mins.

I had to order a small set of TT20 bits to get the security screws out of the back. I ordered them from an online retailer. Once the security screws have been removed and the Phillips screws, the cover can be lifted off and away. My cover was stuck in the front. I had to wiggle it to get it to break loose from the tongue and groove seam. I had ordered a Magnetron, a fuse, a HV Capacitor, and a Diode. It did not take that long to replace the parts. I figured if I was that committed to get into it I would replace all of the parts. It's back together and it heats like New???? I did not realize how noisy the Magnetron had become over time. Now it's quiet. For half the price of a new one, it's up and running like New! Go for it.

First step was to make sure capacitor was discharged before touching other components.Used multimeter (VOM) to check out components, diode, capacitor, and magnetron. Ordered all three as readings were not consistent with expected. Started by replacing magnetron. Tested with cup of water. Viola microwave was heating the water. Returned the other parts. Super service. One caution is to make sure capacitor is discharged before doing any work as it contains high voltage. Safety first.
