66993 (CSSESEA) LG Microwave - Parts

This micro-switch is designed for use in your microwave. The function of this part is to monitor the door latch position and communicate to the electronic control board whether the latch is open or closed. If your microwave does not provide heat, or will not start properly, you may need to replace the micro-switch. This part is approximat...Read moreely 1 inch in length and 3/4-inch in width. It is made of black plastic with two metal prongs. This is an OEM part sourced directly from the manufacturer. This part is sold individually. Be sure to disconnect the microwave from the power source before you begin this repair.

This microwave door interlock switch responds to the door latch, helping prevent cooking operation while the door is open. Its small actuator changes the electrical contact when the door opens or closes. A worn or damaged switch may prevent the microwave from starting even when the door is fully shut. Replacing a faulty switch helps resto...Read morere proper door detection within the safety interlock system. Internal microwave components can retain a dangerous electrical charge after unplugging, so disconnecting power alone does not make them safe to handle. This is an OEM part sourced directly from the manufacturer.

Electrical overload protection comes from this microwave time delay fuse, rated at 20 amps and 250 volts. It tolerates brief startup current while opening the circuit during a sustained overload or short circuit. A blown main fuse may leave the microwave without power or prevent it from starting. The fuse cannot be reset and requires repl...Read moreacement once it opens. Internal microwave components can retain a dangerous electrical charge after unplugging, so disconnecting the power cord alone does not make internal handling safe. This is an OEM part sourced directly from the manufacturer.

The turntable support assembly is also known as a roller guide, fits under the cooking tray and is used to support the tray and to engage the rotating coupler. If your cooking tray will not turn, or rumbles when it turns, check the support assembly for signs of wear or damage. If no damage can be seen, check the coupler for damage.

This tray rotates in your microwave ensuring more even temperatures.

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.

This microwave high voltage diode and cable assembly allows current to flow in one direction, working with the transformer and capacitor to supply power to the magnetron. That power enables the magnetron to generate the microwave energy used for heating food. A failed diode may leave the appliance running without producing heat. Replacing...Read more a faulty assembly helps restore normal heating circuit operation. Internal microwave components can retain a dangerous electrical charge after unplugging, so disconnecting power alone does not make the circuitry safe to handle. This is an OEM part sourced directly from the manufacturer.

Power for microwave heating depends on a high voltage circuit that includes this capacitor, the transformer, and the diode. The capacitor stores and releases electrical energy to help supply the magnetron that generates microwave energy. A failed capacitor may cause a loss of heating, loud humming, or a blown fuse when cooking begins. Rep...Read morelacing a faulty component helps restore normal circuit operation. This capacitor can retain a dangerous electrical charge after the microwave is unplugged, so disconnecting power alone does not make it safe to handle.
