Question about Panasonic NN-S561 Microwave Oven

1 Answer

What cause the wattage difference?

Have 2 panasonic microwaves: NN-S532 and NN-S542. I want to use 1 to repair the other. 1 is 1200W. The other 1300W. Same Invertor board & Magnetron part numbers. So what make the wattage different?

    SHARCNET: The fans and all components are the same, except the keypads! They are different and have a few small components onboard that probably do, as you said, make a higher power selection on the 1300 W unit, that the 1200 W keypad does not offer. Like AMD does with one cpu design sometimes. They leave a bridge open on one and closed on another and sell it as two different power models. Thanks!!

Wattage is based upon voltage & current. I would think that on the 1300W unit, either the voltage or the current is higher than that which is used on the 1200W unit.

Perhaps the magnetron in the 1300W unit is being driven harder. Are the fans the same size?, The magnetron in the 1300W could be running harder and they have a larger fan in it.

In any event, if the part numbers are the same, you should have no trouble using one units parts to fix the other.

Good luck!

Microwave fuse keeps blowing on my Panasonic Microwave NN-9854P

I would check the door interlock switches and then if that doesn't fix it replace the invertor board and possibly magnetron.

Panasonic Microwave Oven NN-S262BF It starts to run and stops after 3-5 seconds

The problem sounds like it is in the keypad controller, behind it there is a microprocessor with additional parts that work in conjunction with the hardware, if there are issues there the cost to repair would not be justified, better option is to replace.

Our s333 panasonic microwave stops working after 1 second?.. it just shuts off?? can you advise?

It probably requires a new magnetron or an invertor board or both. Take it to an authorised Panasonic repair agent for an estimate for repair.

H97 fault code on a micro wave. What is the estimated cost to fix? Is it cheaper to buy a new one?

Either te magnetron has failed or the invertor has failed.
How long is a piece of string.
Ask a Panasonic Authorised Repair Centre for an estimate.

Panasonic genious sensor inverter 1300w nn-t664sfx displays code "h98" & will not run - what's the problem?

Mine did this once and it was the magnetron. Once replaced, it worked fine. Repair is an option if it is still under warranty or someone will do it on the cheap. Otherwise, just get a new microwave, since this is the main part.

Microwave turns off by itself after being on for 3 seconds

See if this describes what's happening:
  • Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector
If so, see and

Otherwise, 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.

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

Panasonic Model No. NN-S933BF Microwave Oven

No sorry the issue will be with eiher the inverter, the magnetron or the main timer board. There is a tracer signal that comunicates through these components and if it doesnt get to where it is supposed to go it wil just shut off, the big hint at that is the time interval. It is not something like a sensor heating up and causing a fault. it is not running long enough to get any thing hot it is in the electroincs. Too expoensive to repair, im sorry better to get a new one. Good Luck
