Neff Microwave has failed.It no longer heats anything.Neff

Customer Question

Neff Microwave has failed.
It no longer heats anything.
Neff C57M 70N0 GB/03.
It has a conventional oven function, which appears to be fine.
When using Microwave:
1) set 1000W, 60sec, Start: Unit shuts off after 20sec. No heating.
2) set 90W, 60sec, Start: It completes the cycle. No heating.
The main fan runs. No error messages.
It might be my imagination: Is there a second fan associated with the Microwave? If so, I think this fan does not start.

Hi Kevin, thanks for this info.
I'll hold off on rating for a bit, as I am researching the fix, and may need to ask further details.
I can see the magnetron and inverter assembly are available on ebay, and there are a few suggestions around for determining if the magnatron is broken.
Expert:  KevinWhiteJA replied 2 years ago.
OK, however I won't recommend a DIY repair with Microwave as these units have HV even when turned off

Understood, and thanks.

You're welcome... let me know how it goes

Yes - it was the magnetron.
It passed the simple open and shorts test with a multimeter.
I googled the partnumber of the inverter and found a Panasonic manual that provided some simple tests that suggested that everything except the magnetron was working correctly. So I change the magnetron, and it's fine. Many thanks for pointing me in the right direction.
