Daniel M Bainbridge Island , WA December 06, 2015 Appliance: Model MAYTAG (WHRILPOOL) UMC5200BAB Dead microwave Replaced magnetron and diode. Followed video directions. Magnetron cheaper by its own model number rather than the one listed for my microwave (same part). Still purchased at Appliance Parts, but saved some cash. Disassemble first before ordering. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
