Microwave energy for heating food is generated by this magnetron, which converts electrical power from the high voltage circuit into cooking energy. A failed magnetron may leave the appliance running without heating, even while the turntable, display, and fan continue to operate. Replacing a faulty unit helps restore the energy needed to ...Read morewarm and cook food. Internal microwave components can retain a dangerous electrical charge after the appliance is unplugged, so disconnecting power alone does not make the internal circuitry safe to handle. This is an OEM part sourced directly from the manufacturer.
Current flows in one direction through this microwave high voltage diode and cable assembly, which works with the capacitor and transformer to supply the magnetron. This electrical process supports the microwave energy used to heat food. A failed diode may cause a loss of heating or unusual humming while the appliance runs. Replacing a fa...Read moreulty assembly helps restore normal high voltage circuit operation.

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

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.
