Replacing a magnetron in my particular 9-year-old microwave (a microwave/hood combination) was not a simple “plug & play” operation. That is why I am placing this in the slightly difficult area. First, it takes 2 people to remove the microwave from the top of the stove. Next the main outer panel need to be removed. After that, 2 sheet metal panels need to be removed in order to expose the high voltage components for testing. Always discharge the high voltage capacitor first before doing... Read more

Do-It-Yourself Stories from Customers like You Microwave turntable motor overheated and melted tray coupler   Terry H. • Columbia , MO • May 31, 2018

Obtained the replacement motor and tray coupler from Appliance Parts Pro. Video of the typical replacement was very helpful to show what to expect and how to replace the motor and coupler. The removal of the bottom plate was held in place by several phillips screws. The motor was attached with two torx screws. The electric connection clips to the motor required needle nose pliers to pull them off. The tray coupler was simple to install after the motor was secured and bottom plate was replaced.. Read more

Do-It-Yourself Stories from Customers like You My microwave was working at half power   Eric H. • Tonawanda , NY • October 30, 2015

Once the new parts were in and everything was reassembled the microwave worked good as new. The repair was less than a third the cost of replacement and no special tools are required. Just be careful to discharge the capacitor. This website is a great resource. Read more
