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 m...Read moreicrowave 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.
Usually found kitchen appliances, this OEM-certified diode cable assembly helps to convert power from the transformer to the magnetron, to heat up your food. A damaged cable assembly will cause your appliance to heat food inconsistently or to not work at all. You might notice a burning smell or a loud buzzing sound coming from your applia...Read morence. If you do not replace a broken cable assembly, the components that produce heat in your appliance can overheat and fail. To replace your cable assembly, start by unplugging your appliance from any electrical source. Remove any protective casing from the assembly by unthreading any screws or clips. Disconnect the cable assembly from the transformer and the magnetron with pliers. Reinstalling a new cable assembly requires you to reverse the previous steps. Please keep in mind that this cable assembly is sold individually.

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

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.

It didn't work. It was too large. I need a glass tray NO LARGER than 13 1/2''. I received a 14" that was suppose to be comparable to the 13 1/2" glass tray that broke. The 14" is too large and wobbles. IF you have one that will fix my LG over the stove microwave Model # LMH 2016ST I would love to give it a try.

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
... Read moreand 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.
