Whirlpool Microwave Magnetron (WPW10693025)

The Whirlpool Microwave Magnetron is the core heating component in your microwave, responsible for generating the microwave energy that heats and cooks food. It works by converting electrical power into microwave radiation, which is directed into the cooking cavity to rapidly heat food from the inside out. Without a functioning magnetron, the microwave cannot produce any heat at all.

The Whirlpool Microwave Magnetron can fail due to age, repeated power surges, running the microwave empty, or damage from arcing caused by metal objects inside the cavity. Internal components like the filament or antenna can burn out over time, and the magnetron may also overheat if the cooling fan or ventilation system is not working properly.

Watch for these symptoms to help determine if the magnetron is the cause of your microwave problem:

- Microwave runs but does not heat food at all

- Food heats unevenly or takes much longer than normal

- Loud buzzing or humming noise during operation

- Burning smell coming from inside the microwave during use

- Microwave trips the circuit breaker when started

- Visible burn marks or arcing inside the cooking cavity

- Microwave shuts off shortly after starting
