Part #6324W1A001L
This magnetron in your microwave creates the radiation needed for cooking or warming your food. It is located inside the main cavity, typically near the transformer or waveguide. When the magnetron becomes defective, your food may not heat up properly or heat up at all. Additionally, buzzing or humming sounds may be noticeable while the microwave is in operation. With a malfunctioning magnetron, your microwave loses its primary function. To remove it, you first need to unplug your microwave from its outlet. Before touching any components, discharge the capacitor by placing a screwdriver, with an insulated handle, across the two terminals of the capacitor. Once the capacitor is discharged, replace the current magnetron by disconnecting it from any wires and removing any mounting screws or clips. This magnetron is sold individually and is supplied directly from the original equipment manufacturer.

Over the stove microwave installed in top cabinet row.
1. Unplug device.

Would not heat and made a buzzing or popping sound

Unplug the microwave. Remove the Philips head and safety Torx head screws along the bottom of the sides and rear of the microwave which hold the black cover on. Lift the cover up at the rear and slide it backwards to disengage the tabs on the front top. Remove the cover. Discharge the capacitor by shorting the terminals to each other and then ground. Do this with a well insulated object and be aware there may be a pop when you do this. Keep hands, etc. on the insulated part of the object (screwdriver handle, etc). There's a lot of stored energy in that capacitor. I'd advise first checking the diode to make sure its not bad. Replace it if it is. The Magnatron is held in with a couple of screws on the top and sides. Unplug the connector and remove the screws. Remove the Magnatron. Installation is the reverse of removal.
