Do-It-Yourself Stories from Customers like You Magnetron   Todd P. • Greeley , CO • April 29, 2022

I researched the problem. Found the solution online and ordered parts from AppliancePartsPros.com. It only took a screwdriver to make the repair. The only confusion I had is my model of microwave had a double diode, and the one sent to me (by model number) was a single diode. I wasn't sure what to do, either install the new single one or put the old double unit in. I went with the new single diode, and it works fine. I don't know why the two differences, but it all worked out. Read more
