I have a Thermador model smw272 with a built in microwave

It does not heat well. It is losing the ability to heat food at the same rate that is has in the past.

I tested the temp rise with 32oz of water and the temp rose 12 degrees in one min on high power.

Do the magnetrons lose power over time or do I have another issue.

Thanks for the help

Hi.

Yes, the magnetron may lose the power over the time.

Please provide the complete model number.

Thank you.

It is a Thermador SMW272P oven.

The microwave is built into the unit and upon further inspection its magnetron is a Panasonic 2M261-M32

Thanks

Hi.

The microwave you have is using an inverter power board, which is no longer available.
The chance that it's the magnetron is 50/50.
Try to replace it. If it will work - you are lucky.
The good think that you can return any parts even if they been installed.

The magnetron Part number: 487757

Replaced the magnetron and the unit condition remains the same.

Time for a new microwave. The GE JEB1860SMSS has the same dimensions
as the Thermador model 11 15 157 microwave.

Thanks for the help
