Capacitor
Part #0CZZW1H004B
Store the electrical energy needed by a microwaves high-voltage heating system with this replacement capacitor. During cooking, the capacitor works with the transformer, diode, and magnetron to help create the energy that heats food. A faulty capacitor may be linked to no heat, loud buzzing, or a fuse that blows when cooking begins. However, these signs can also come from other high-voltage components, so proper testing is important. Microwave capacitors may hold a deadly electrical charge even after the power cord is unplugged. For this reason, testing and installation must be completed by a qualified appliance service technician.

Motor Burned Out On Turntable

My 8 year old daughter cleaned the inside of the microwave with enough water to rival a tsunami. Resulted in a clean microwave with a fried out motor that no longer revolved. Part came quickly. Took cover and bottom off to get to the part. One screw held it on and a plug. Removed those, put on new part and she was good to go. No tri p to home depot today.

Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover .
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.
