    I have the identical porblem. One issue is that the unit is only rated for approx 1400 amps and I have had it checked - it is pulling 1900 amps which is dangerous! The wiriung in the house and the unit are not designed for this much current. Has anyone solved this porblem?

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb.

In many over-the-range models, that can mean having to take the oven down from the wall! For safety's sake, that should be a two-person job.

It's really helpful if you have your original installation instructions to do this.

Many models use one halogen lamp to illuminate the cooktop and another to illuminate the cavity. You must not touch them with your bare skin as the oils will shorten the bulb life.

SOURCE: panasonic microwave does not heat , but the rest seem's to work?

High voltage parts are suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing either the magnatron or the high-voltage capacitor and diode. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

SOURCE: How do I remove the sensor inverter on the Panasonic NN-S96OWA ?

That's a misnomer.

And oven may have an inverter and it may have a sensor (usually either a heat sensor or humidity sensor).

Microwave stops mid cycle


If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

Panasonic 1200 watt microwave oven model:NN-S561BF,year:May 2001.When trying to heat foods the unit runs for 5-10 seconds then stops,I don't sense any heat.Anyone have any common repair tips? as I have...


Wow you must have been a TV repair tech too. Salute!! They have gotten more safisticated but some things never change. The magnetrons are real reliable. If the unit runs for 5 to 10 seconds it sounds like a control issue. The only other possible problem could be a bad HV diode. The new units have the safistication to know when the magnetron is not working and would shut down. Certainly an easy and cheap fix. You seem to have the expertise to explore this. Let me know how it works out or if you need more info. Thanks for using FixYa.

Micro Wave shuts down


If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

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

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.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

If you do indeed have a problem, Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

I would recommend that you contact your nearest Panasonic-authorized servicer.

Panasonic NN-T994SF 1250 watt countertop microwave stopping


From my research, this sounds like a fairly new model. Consult your user's manual to see if this is a user, or common issue. If nothing is descibed then I would seek possible warranty service, or dealer replacement
