My panasonic microwave model # NN-S540BFW stops after 4 seconds after you hit the start button and cuts off on its own. What is wrong with my microwave?

yes you are right, do NOT open door when MW is operating. You need to get the "Interlocks looked at. Always ask for a "Quote" before proceeding with any work.

UNPLUG AND DONT USE you have a bad or wet control board . if you gave cleaned the keypad in the last day or so , it might dry out in a few days ......if not it just went bad . most control boards are between 130.00 and 160.00 without looking up your oven ... so in most cases its not worth the repair

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

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

How long did you unplug it to reset it?

If you unplugged it for a good long time (minutes or hours) , then I would bet have a failed keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can order Panasonic parts here. Or you can contact your nearest Panasonic-authorized servicer.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Please feel free to contact me directly if you need more help.

was there any motor that should run as you turn it on, the fan inside and the rotating table motor. try to replace that micro switch at the door that bubbled out and burnt. try to test or replaced right away the industrial diode that is connected from the capacitor to the ground of the microwave.

Hello Two options to try:

1) Press the Clock / Timer button 3 times

2) Unplug, wait a minute, then re-plug to power up with the factory settings. You will need to reset your clock and any favourite settings.

This should work with all Panasonic Microwave models.
Good luck
