Panasonic NN-S753 Microwave Oven - Answered Questions & Fixed issues

Follow the instructions on page 10 of this manual.

Hi I have a Panasonic combi oven in between the glass door is misting up should I be worried

The parts can be ordered from the Panasonic authorized parts rep. You have to contact Panasonic for details.

I strongly recommend to have any work on a microwave oven done professionaly. There are radiation leakage issues if the door is not re-assembled properly. After doing any service the microwave oven must be tested for radiation leaks. I doubt that you have the radiation testing equipment to make sure that there are no leaks.

HI:
You have a faulty door switch, the unit is not supposed to come on when the door is opened only the light.This unit may require servicing as the control board may also be at fault.

The magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

You may have a bulb on the right side ,if correct then remove the clock panel and access it from there.If not remove the shell and lift off the microwave cover to get to bulb

check the door switches

hi, check that the cooling fan is operating and to sufficient speed to cool the magnetron or the thermal cutout mounted to the magnetron will cut power

not sure on panasonic but most of them turn with a little gear drive. maybe the gear is stripped or off location.

Alot of the Panasonic models had the Transformer and Capacitor and Diode built into the power board situated bottom right as you look at the appliance.
Dont know of a way to actually discharge this arrangement.

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.

hardware store..

it is obvious that nthe microwave side of the unit is not working.
microwaaves have a terrible habit of blowing fuses for the most stupid reasons. No not the fuse in the plug but the ones the manufacturer hides inside the case, you will have to look hard. if one is blown replace it with a direct replacement. and do not test the machine with the cover removed

Hi, if it went dead while it was in use, then it sounds like the HV section (magnetron, HV diode, inverter section - if used, etc) has failed, possibly only economic to fix if it is a convection microwave.

Hi , Either you have a faulty door interlock switch(es), or the door latches (on the door) have been damaged and will not activate the interlocks. either way, you have to be conversant with adjusting microwave latch assemblies once the repair has been effected AND THE USE OF AN OVEN LEAK DETECTOR IS IMPERATIVE for final testing or the end user will be subjected to harmful levels of microwave radiation.

the main control board is "seeingf" a high amprage draw from the inverter board . you have a problem with the inverter or the magntron . parts are more than a new unit . try to stay away from the inverter type , there just not ready for prime time . google "panasonic inverter reviews " and you will see just common your problem is good luck

In the picture on page 12 of the owner's manual it says it is 1100 watts.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.
