Could someone advise whether Microwave Oven Inverter boards are interchangeable. They have a supply voltage which is the same with all microwave ovens and control voltage, then the output. I have only seen Panasonic Magnetrons used.

Re: Microwave Inverter Boards
i wouldnt risk it, magnetrons arent all the same.
if you give it too much current you will kill it. -
Re: Microwave Inverter Boards
Thanks for your reply stj, isn't the current determined by the control voltage? The inverters, well most of them look alike. But I understand what you are saying, I guess Panasonic themselves wouldn't have differing part numbers if they were iinterchangeable. I might do some experimenting, but for this particular job I will order the original, as you say it's not a risk worth talking.Comment

Re: Microwave Inverter Boards
if you can find what magnetron each board was designed to drive then maybe you could use a substitute that used the same one.Comment

Re: Microwave Inverter Boards
You'd have to match the magnetron power, you can't pump 1,000W into an 800W tube. The filament voltage, anode voltage and current are close within a family but critical differences. Example: some are 4kV or 4.4kV but that can mean 600W or 1000W. Check your magnetron datasheets:

I've seen Panasonic inverter microwaves use 2M236 and a teardown and older schematic shows 4kV 300mA design output with no O/P feedback:
