The Magnetron is an OEM part for LG microwaves. It is responsible for generating the microwaves that cook or heat the food inside the appliance. The magnetron converts electrical energy into microwave radiation, ensuring efficient and even heating.

Causes of a bad magnetron can include prolonged use, electrical surges, or overheating. Over time, these factors can lead to the magnetron wearing out or failing completely.

Symptoms of a bad Magnetron include:

  • The microwave not heating food
  • Strange noises during operation
  • Burning smell or smoke
  • The microwave shutting off unexpectedly

This OEM LG part is also compatible with Sears/Kenmore models.

Questions & Answers

For Lg Magnetron (Part Number: OEM13372005)

1 Answer

Sam, Not all the magnetrons are the same, the biggest difference is in the wattage of the microwave. You will want to use the recommended magnetron for the unit.

Pat for Model Number 721.67903601

I have a Kenmore microwave model 721.67903601 not much over a year old recently it started just getting food warm but not hot. In order to get it hot you have to cook a lot longer than normal. I opened the unit up and got out the tech sheet that's inside and I tested all the major components they all tested good, they all gave the proper ohms readings that the tech sheet said they would be.. So I'm assuming that even though it has the proper ohms it still must be the magnetron?. would that be correct ??

Hello Bill! Unfortunately, we do not carry parts for the brand Dometic and are unable to guarantee that the inquired magnetron will work on your appliance. Sorry about that!

Hello Hank. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron.

Hello Howard. You will need to replace the magneton and the diode and look for bad connections from the sparking.

Hello Ron, This is most likely a door switch. It is not recommended to replace only one since there are three and all of them will fail soon after the first one fails. You will either need one 3B73361E and two 3B73362F or you can replace the entire assembly as a unit by ordering part number 3501W1A019D.
