You may have a sticky door switch. Try a simple "slamming" of the door, don't over do it, just a little harder than normal. This may help pop the plunger in the switch back up. The switch could have also become loose and moved out of its adjustment.
If this does not help, a technician should save you time and money with this sometimes perplexing problem.

SOURCE: Panasonic NN- A712 combination Microwave 1000w - Switches off after 20 seconds

The 22 seconds is the giveaway.

In most cases, this is 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.

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

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.

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or 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 TCOs or thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

The TCOs you need to be concerned usually with have all black or white wires only. Please reply with photos of your interior if you have questions.

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.

Hi Michael,

i think something wrong with its high-tension circuit or your magnitron is bad.
the minor fault is open of therm stat for protection.
or burnt fuse in circuit.

How do i change the light bulb? Panasonic model NN-T945SF


Hi,

Do you mean you want to replace light bulb for your microwave? If yes follow the instructions below;
  1. PLEASE UNPLUG YOUR MICROWAVE!
  2. Picture of your microwave with a phone or camera so that you don't forget how to assemble it back.
  3. Remove the two screws that holds grill. They are located at the edge of the unit. Once the screws are out, rotate the grill forward from the top. It will pop right out.
  4. Once the screws are out, rotate the grill forward from the top. The grill should pop right out.
  5. Locate a small access cavity on the left.
  6. Remove the screw that is located near the front of the microwave door.
  7. Lift up the sheet metal floor to access the bulb. The bulb is located under the sheet metal "floor" on the left.
  8. Place a flash light on the microwave floor and shine the light in the light area. This will help you see better when you replace your bulb.
  9. Look for a small shiny reflector that hides the bulb. Use your two fingers to squeeze it a bit. Making sure not to bend it.
  10. The bulb connection should come right out.
  11. After you replaced the bulb, re secure the reflector and the sheet metal floor with the single screw. Test the bulb by plugging in your microwave.
  12. Once you see that the bulb works. Unplug your microwave again and re attach the front grill. You are now done.
I hope this helps to solve your problem.

Good luck.
