    Our NN-P294 had this same 3 sec shut down when we 1st bought it. Got it fixed took about 3 weeks fro them to get the parts. Now only 2 years later the door lact mechanism does not open the door. With my soup inside and the latch not working I had to take the microwave down and take it apart only to find that the 3 PLASTIC latch parts had broken. We had no kids, just my wife and I use it we are mid 40's in age and have not abused to door open button in anyway. Lousy design for an opening mechanism PLASTIC!!!

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 (Panasonic NN-S254BF) starts, runs 2-3 seconds, and then shuts off. I have checked the door latch switches, and they are all working like they are supposed to. Whats wrong?

In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.


My NN-T994SFR Panasonic Microwave shuts off after 1 second.

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?

Your temperature sensor inside on the microwave need to rreplace. It maybe dirty or faulty. Bring your microwave to electronics technician to check it.

From my research, this sounds like a fairly new model. Consult your user's manual to see if this is a user, or common issue. If nothing is descibed then I would seek possible warranty service, or dealer replacement

First, get the bulb part #F612E4W00AP or equal. Next, you should find a few screws around a plate in the unit through which the light shows through. Carefully remove them and the glass lens. When replacing the bulb, be sure it is in securely.

On for 2-3 seconds and shuts down with slight wire burning odor.

http://froogle.google.com is showing this model selling for as little as $100. But as a technician, I have never cared for the inverter models. As complexity increases...
