How to Troubleshoot & Replace Lg AP4457332 / 6324W1A001L Magnetron

Replaced Magnetron and works great. Took longer to remove from the wall than it did to replace the part. (4 screws and power connection). Glad I did price comparison as AppliancePartsPros.com was by far the best price. 

Used the schematic diagram inside the case to check components and found the magnetron was bad. Ordered a new component and installed it. It's working great now. Great service and fast delivery from AppliancePartsPros.com at a reasonable price. 

I ordered this part and it arrived the next day and now the microwave is back up and running! Happy wife....happy life! 

Tested all the high voltage components: transformer, diode and capacitor- all good. Replaced magnetron 

YouTube videos pointed me in the right direction. Appliance pros customer service got me the right part. 

After I researched what could be broken, I decided to buy the most common parts listed. I put the Magnetron in first, and the oven worked. So, I have the fuse and capacitor for the future if needed. Doing it myself saved well over $100 for repairs or simply buying new. 

When using "Timer" function turned on unit to cook,empty by mistake! Removed over range unit, and removed cover. Magnetron had pieces of permanent magnet hanging on outside. Ordered parts Received parts (2days) Replaced parts and we have our microwave back, Very simple! About 15min. to fix and 1/2hr. to clean inside unit.
