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.

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.

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

SOURCE: my panasonic nna770s combi microwave cuts out

See if this describes what's happening:

  • Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector
If so, see http://www.microwavedisplay.com/safety.txt , http://www.microwavedisplay.com/disassembly.txt and http://www.microwavedisplay.com/doorsw.txt

Otherwise, if the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.


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

Another Microwave that shuts down after 3 seconds of microwave operation


This model uses an inverter to produce high voltage. That symptom is an usually indication of a problem with the inverter. Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models. And of course at less than 1 year, this would still be under warranty if you have your sales receipt. You should be able to locate a Panasonic-authorized servicer here: http://www.pasc.panasonic.com/WhereTo/FindServicer.asp?Pass=1 I would mention the exact symptom when you call so the technician can bring a new inverter with him when he comes out to repair it. Might save you having it pulled into the shop. Good luck!

Microwave shuts off after 3 seconds


Although your model number doesn't seem to show up, the NNS950-series units are powered by an high-voltage inverter. And yours has failed. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Sometimes a whole new inverter is cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized appliance / microwave repair shops and ask then specifically about inverter component-level repair and simple inverter replacement costs for your exact model number.
