A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to

open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

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.

Panasonic NN-S254BF microwave oven runs for 2-3 seconds and then shuts off'


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://207.234.249.73/mwd/safety.txt , http://207.234.249.73/mwd/disassembly.txt and http://207.234.249.73/mwd/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.

That 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.

NO POWER


Most likely have blown a fuse , get behind the touchpad to ohm the fuse out , replace if blown , if continues to blow check componets for shorts , there will likely be signs of burnt parts.

Faulty microwave oven


So it's dead? (No lights, no beeps when you press a key?)

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

But - this model uses and inverter. 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. You can find one here:
