I have a 7 year old Panasonic over range microwave NN-S263WF which just started automatically shutting off after 5 seconds. Clock light remains lit - it just stops.

Are the filters clean.

We recommend you use the below link to locate an authorized service center. Panasonic microwaves have a 5 year warranty on the microwave.

my over the range panasonic microwave turns off after 5 seconds????

I would check the magnetron and invertor board.

You have a faulty interlock switch (which the door operates).
This needs to be renewed by a qualified microwave service technician ASAP.
A potential hazard if not fixed immediately!

My unit shuts off after about 2 seconds. It seems like it tries to go, but it sounds like it stops working and then 1 or 2 more seconds run off and it shuts down. Then you hit start again and it lights up inside and then shuts down. It's only about 2 or 3 years old.Any solutions?

No sorry the issue will be with eiher the inverter, the magnetron or the main timer board. There is a tracer signal that comunicates through these components and if it doesnt get to where it is supposed to go it wil just shut off, the big hint at that is the time interval. It is not something like a sensor heating up and causing a fault. it is not running long enough to get any thing hot it is in the electroincs. Too expoensive to repair, im sorry better to get a new one. Good Luck

Try unplugging the microwave for about 30 seconds, then plug back in. This may work. What you are doing is resetting the micro processor.

could it be that i didn't follow the manuel because i got it second hand or is it because something is wrong with it,and i have to get it fixed.

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.
