Panasonic Inverter NN-V673S microwave- shuts off after 2-30 secs
I have a Panasonic Inverter NN-V673S. The microwave worked for about 2
years. Now, the microwave runs for between 2-30 seconds (different
every time) on any setting i choose, then shuts off- e.g. I set it for
a minute, it works for 30 seconds, then lights turn off, yet fan keeps
humming, no heat produced and there is only a ":" on
Please tell me how i can fix this, preferably at home, as I don't want to pay for having it repaired.
I olive in the UK, so finding a panasonic repairsman is difficult
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.

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.
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:
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.
