Panasonic microwave s254bf stopped working

Get a Panasonic unit. They are the most efficient and under $100.

We regret reading about your microwave. At this time we recommend you have the unit evaluated by an authorized service center.

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.

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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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.

the child lock feature is activated.

if you can look at your manual, it would be stated there how to activate and deactivate your child lock option.

may be magnetron spoiled or high voltage section problem,please check circuit andreplace damage parts...

your Display board will need to be replaced

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:

check mains fuse and check control circuit and magnetron. and diodes capacitor  high voltage related circuit. small part also gone microwaveoven doesnot works, first check oven and conform which part was spoiled, after that this is worth or not old ovens good compaare to new ones...
