Question about Panasonic Microwave Ovens

Open Question

The panasonic micro/convection oven (NN C 867 BV) in my 2000 Rv does not turn on at all. I removed it and tried it on a house outlet still no dice. After removing it there was a baggie with 2 fuses (18 amp). I have not unscrewed the back yet, just wondering about the shock thing. Is it obvious what I should not touch? What if the fuse is not the problem?

A microwave can be dead for many reasons.

It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

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 convection oven nn-cd989s, complete power off during prebake cycle of 450 deg which was directed to remove light oil coating from manufacturing process . Now unit has no power on face panel


Check the 20 amp fuse where the power cord ends inside the oven. If it is open check the latch switches. If the switches check ok the invertor is probably bad, smoking.

When started,light& turntable operate normally,but no heating by microwave. Transformer normally sounds smooth,but now makes rattle or vibrating noise,like something is loose.


Check the door safety intertlock micro switch for proper behavior. If it is faulty, the oven will think the door is open and will not turn on the magnatron.
