Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

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

SOURCE: Panasonic Sensor 1250W Microwave cycles off after only 5 seconds.

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://www.microwavedisplay.com/safety.txt , http://www.microwavedisplay.com/disassembly.txt and http://www.microwavedisplay.com/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.

SOURCE: Where does the fuse go in a Panasonic Microwave

Follow the power line from the outside to the inside towards the magneto the fuse will be located inline. You have to remove the outer shell of the microwave to access this area. Also do not touch both sides of the fuse terminal at any one time due to a nasty shock from the capacitor

Manual for Panasonic sensor 1250w


Do you mean a Panasonic 1250W microwave with 'Genius Sensor' technology? If so, you should check the model number on your microwave to find the correct manual.

Panasonic has several models with sensor modes. The manual will usually be on the product page. Search for the model from http://shop.panasonic.com and scroll down to the manuals section. Alternately, go to http://shop.panasonic.com/support , then do the model search. This will automatically go the the Owner's Manual section on the product page.

A manual for the NN-SN933 (and several other models) is here: ftp://ftp.panasonic.com/microwaveoven/om/nn-sn943_nn-sn933_nn-sn743_nn-sn733_en_om.pdf . This is a 2.2 cu. ft. model that was advertised on target.com as a Genius Sensor microwave.

I hope this helps. Please add a comment with the model number of your microwave if you need a different manual.

Panasonic genius inverter 1250w door stuck


Sounds like a spring let go, or the plastic piece that the spring hooks onto broke. Either way, the top cover will have to come off. Could be an easy fix unless something broke.

Panasonic 1250w buzzing noise in first 3 s and then stops abruptly regardless of time set. Gives a faint burning smell when opened.


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.

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

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.
