Panasonic NN-S952WF Microwave

Then microwave lights, fan and carasol start running when I open the door. I do not think the microwave is cooking but I won't chance it. Otherwise it works fine. What can cause this?

H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

In Canada, you can find an authorized Panasonic servicer here.

SOURCE: Microwave shuts off after 2 seconds

If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

If it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer (above) to get it fixed free.

SOURCE: panasonic microwave nn-s963bf making grinding noise

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

You can
order parts for this brand from Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

SOURCE: Have had Panasonic microwave NN-S753 several

Thanks for that ID number. That's a big help.

Now, looking at the schematic, it's clear that you would have a shorted primary latch switch (top door switch) or that switch's mount is damaged.

For safety, disassembly and diagnosis of door switch trouble, see my generic files:

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

SOURCE: our microwave oven Panasonic NN-S252WF stops after

Our technician suggest that there may be a problem with the Inverter Board in this model, which is something that would need to be looked at by a Service Center.

In rare cases it could be the door switches.

PANASONIC Microwave Inverter #NN-SD697S. Everything works except the START button. Works sometimes, and not other times. Checked outlet, all was good.


This is either the door sensing switch (most likely) or a bad membrane switch [start switch] (that's what Panasonic calls it) on the touch pad. The contacts on the door sensing switch can be slightly contaminated and not read "zero ohms" to the control PCB. The control board thinks that the door is open and it will not allow the cook cycle to start.

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.
