Panasonic nn-s255 wont turn on

Mine did the same thing. turned out to be a overheating transformer on the inverter assembly.

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?

I have same problem. Disconnect the power. Take the 3 screws out of the top of vented front thus exposing 2 screws that hold down the touch pad .remove them and move touch pad out of the front and out of the way. on the extreme top right within the compartment there is a circuit board that has a fuse on it. replace the fuse and try to restart the microwave. if the fuse blows again you have a major problem probably the magnetron. If you need further help call me (403)870 9110.........Ron

there is a switch to turn it on or off. the turntable is replaceable

If your oven is out of warranty then i would suggest just getting a new one.

The code is for a bad controller circuit, and it would cost almost as much to fix it as it would to buy a new one.

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.

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

The 22 seconds is the giveaway.

In most cases, this is a problem with the inverter or a bad magnetron.
