Panasonic Microwave Ovens - Page 6 - Recent Questions, Troubleshooting & Support

I wouldn't advise you to use it unless it stops when you actually hit the off button. if it stops when you hit the off button it would be OK to use but only an adult and somebody who knows that the microwave is faulty. it sounds like one of the door switches is bad. there can be anywhere from 2 to 4 switches on the door. Normally open and normally closed switches are used on the door so you must always make sure you get the correct switch you can check them with a meter but you must open the microwave up which I think I would leave to somebody who knows about Microwaves.

Check cooling fan is working or not if working check PCB assembly for loose contact or soldering.

There is no such adjustment given,problem is due to faulty power supply section on the PCB assembly,check & replace faulty component.

Check for faulty power supply circuit in the PCB assembly,check the components & replace faulty components.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

Let us know if the hard reset does not fix it.

Please reply back with your brand and model number so we can help you.

Normally 40W, but check the bulb label near the bulb socket.

And of course, be sure to unplug the oven before removing or inserting bulbs, or the control board may be damaged. (I regularly repair these boards because of this.)

there is a motor under the underside of the microwave these motors can clog up. try turning the motor to by hand a few times so it makes a werring sound. if no sound its the slow gear in the motor broken and will need a new motor fitting.

Go to this site, enter your model in to the search bar and it's going to link you to the right model, they have almost everything: https://gdgtpreview.com/category/pdf-manual-directory

The usual cause is the tray motor assembly, or the power supply that feeds it. These parts are available from the parts rep for Panasonic. Contact Panasonic for details.

There are serious safety issues when servicing microwave ovens. I suggest to have the oven professionaly serviced by an experienced service tech for these products.

Type S333 indicates something about the internal build; it's not the model number. Most Panasonic microwaves have a model number that starts with NN-S followed by 3 numbers and several letters. One microwave with the Type S333 on the serial number plate is the NN-S740BA. The manual for that is on the product support page: http://shop.panasonic.com/support-only/NN-S740BA.html . The direct link to the manual is ftp://ftp.panasonic.com/microwaveoven/om/nn-s740_mul_om.pdf . Please check for the actual model number. Add a comment with that model number if you would like me to search for the manual. I hope this helps. Cindy Wells
