GE Microwave Magnetron (WB27X10876)

The GE Microwave Magnetron is the core component responsible for generating the microwave energy that heats and cooks your food. It works by converting electrical power into high-frequency microwave radiation, which is directed into the oven cavity to raise the temperature of food and liquids. Without a functioning magnetron, your GE microwave or Advantium oven cannot produce any heat at all.

The GE Microwave Magnetron can fail due to age, power surges, running the microwave empty, or damage to internal components like the filament or antenna. Overheating caused by blocked vents or a faulty cooling fan can also shorten the magnetron's lifespan and lead to complete heating failure.

Look for these symptoms to help determine if the magnetron is the source of your microwave problem:

- Microwave runs but does not heat food or liquids

- Burning smell or visible arcing inside the microwave cavity

- Loud buzzing or humming noise during operation

- Microwave heats unevenly or only partially warms food

- Microwave trips the circuit breaker or blows a fuse during use

- Display and turntable work normally but no heat is produced

- Microwave shuts off shortly after starting due to overheating
