Panasonic microwave oven nns952wf runs when door is open

The door switch is adjustable. one or more need adjusting to solve the problem

HI.oven has a small DC motor thats turns the turnatable..Now if turntable does not rotate then yuo need to remove the bottom cover of the oven..Unscrew it and check if motor is working ..You can check continuity of the motor using a MULTITESTER..If it is short-circuited or not.Hope this helps.FAN and turntable is being run by this DC motor..Hope this helps.

The cooling fans run for a time after the magnatrons have stopped, The magnatrons are the heating components so I dont think you are in any danger as the microwave doors are double locked so the magnatrons cant run once the door is open

call the toll free number for the product, service centre might assist, I would not use until fixed

The door interlock system has beem compromised , meaning it shifted out of position or the interlock has broken. Dont continue using it like that it will eventually blow the fuse.

Just cleaning is not enought.The terminal is loose and that isusually the problem most of the time.Replace them with new ones and I think you be happy.

all microwaves have 2 safety switches at least... but these are tied to a set of relays that turn it on, my bet is a sticking or stuck relay because you unplug it right and plug back in its not running?-relay ... if always runs driver transitors.

Found this Panasonic post in the Samsung section!

If it moves just a tiny bit when the door opens and then stops, that's normal.

If it keeps running when the door is open, that's usually due to a bad door switch or broken / loose door switch mount.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and

It is possible that the magnatron is bad but hard to say on a no heat problem without checking all components. A lot of model give 5-7 yr warranty on that part.
