Re: Panasonic NN-A554W Microwave stops during microwaving.
What readings should you get with the magnetron?
I’m measuring 0 ohms across the terminals with the leads removed.
And open circuit from earth to each pin.
I believe this is ok but this is with the 9v battery of the multimeter and may be breaking down under full load?
Do the invertor pcbs fail much
Or is most likely still the magnetron?
Failing that what about a over temperature cut out? What do they normally read across them on this model?
Any help appreciated as I have exactly the same problem.
I’m guessing that it’s unlikely the control PCB as the microwave ‘appears’ to work for about 10 seconds then stops. If it was the control panel not running for the correct time presumably it would work for only ten seconds but still heat for this time but it isn’t.
