Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP button) is the primary cause of door switch failure. You can visit my Web site at _ or e-mail at _ if you'd like more in information on diagnosing and repairing this problem.

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 high-voltage capacitor and diode. If that doesn't solve it, then it needs a new magnatron. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

SOURCE: Panasonic Inverter NN-V673S microwave- shuts off after 2-30 secs

If the screen is showing a fault number or a number you havent seen before then its probably a program fault which can't be fixed. Check that the vent holes on the back of the oven aren't dirty and ensure that the whole oven is clean inside. Sadly it sounds like a program fault which cant usually be fixed by the owner though.
Finding a Panasonic oven repairer in the UK shouldnt be a problem though. My parents had a simlar problem wth their Panasonic Inverter oven, called the UK customer services and Panasonic contacted an authorised repairer in Scotland to visit them. Call customer services on 0844 844 3868.
If the call out charge exceeds £80 then you're probably better off buying a new oven.

SOURCE: Panasonic Microwave Oven Stops After 15 seconds - Never Heats

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

You can order Panasonic parts from Tritronics.

The microwave keeps stopping


If you are actually selecting heating time rather than pushing the "quick heat" button, the control board may be defective.

My over the stove microwave will run however no heat. Popcorn digets do not count down but set numbers do. odd odor.



Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
 Q - The microwave display counts down and the inside light is on,  but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.

Q - The fan in my microwave oven is not running will this hurt my microwave?
A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace.

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

Nnt553w panasonic microwave. Whilst heating something he oven stopped and the display said refer to operating instructions. Now seems to be working but doesn't heat.


When you enter the time and press Start:

Does the inside light come on?

Does the turntable rotate?

Do you hear the internal cooling fan running?

Does the time count down?

Panasonic Microwave NN-A770S getting hot on right side externally


If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms. The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating. As long as you have good air flow through the vents, it sounds okay.

Microwave will not heat


Had the same problem--the timer would even count down. The magnetron fan would not turn on, and the microwave would not heat. Checked out several components, but ended up being just the door latch out of adjustment! Be sure to discharge the capacitor before messing around in there. It keeps a charge even when unplugged. Short out the unused terminal on the capacitor to a screw in the chassis, using a short length of insulated wire.

My microwave runs for 30 seconds and stops


It could be shutting off because of the heat sensor on the magnatron is over heating because of a bad capacitor or diode or the power transformer its self. This is a call for the service man BUT you know these days a microwave like this cost a couple of hundred bucks maybe a little more too. But it will possibly cost 150 or so if not more to fix the average microwave. If you really like it, then see if you can have it estimated BUT its not for the handy man to try to trouble shoot as theres extremly high voltage in these puppys even when they are not plugged in!! Good luck

Microwave runs, stops and counts down, starts again, etc.


It sounds like its over heating or the magnatron or the Hi voltage transformer. if you open it and start it a fan should be cooling off the magnatron if its not then the fan is bad and thats your problem Worse case is that the power transformers drawing too much current and over heating and shutting down the first problem i explained though I've seen a hundred times. BUT BE very carefull as there is hi voltage inside this puppy and I've seen it grab and throw a grown man across the room!!!! if you know nothing about electrical or electronic devices its best that you leave this repair to a pro. Good Luck
