Capacitor

I looked online and found that the problem could be a bad magnetron, a bad capacitor, or a bad diode. I received a quote of $485 plus sales tax from an appliance repairman to remove the oven, replace the three parts, and re-install the oven. Instead, I ordered the three parts from this site.. My son-in-law and I removed the range below the microwave and then the microwave itself. It's a two-person job for an above-the-range oven. I was careful to discharge the capacitor before doing any repairs. The parts were easy to replace. The new capacitor was a little larger than the old one, but it had the right specs. With a little maneuvering, I got it in. We re-installed the microwave back above the range, re-inserted the range, and we were in business. So far it works great. I saved more than half of the quoted repair price and more than the price of a new one. I might have bought a new one, but this model is no longer made (mine is 11 years old). The new ones I looked at didn't match well in either appearance or size. Overall, a good experience and a good outcome.
