I would still suspect the top door switch. You would need to operate the switch to see if it clicks both ways and ultimately a test with a meter is required. If you don't have a meter, you can connect wires to a battery and a flashlight bulb, etc., and use that as a continuity tester. On the door switch, COM is common, NO is normally open, and NC (if present) is normally closed. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find thew whole service manual (in sections) and order parts by entering your model number (without the dash) here: http://www3.sears.com If it's not the door switch, I would suspect the control circuit board (the one behind tghe keypad) and we repair these nationwide for only $39.95.

PANASONIC Microwave Inverter #NN-SD697S. Everything works except the START button. Works sometimes, and not other times. Checked outlet, all was good.


This is either the door sensing switch (most likely) or a bad membrane switch [start switch] (that's what Panasonic calls it) on the touch pad. The contacts on the door sensing switch can be slightly contaminated and not read "zero ohms" to the control PCB. The control board thinks that the door is open and it will not allow the cook cycle to start.

My Panasonic 1300w microwave will not turn off. It doesn't cook but won't turn off without actually unplugging it or opening the door and leaving it open. Any help?


You may have a shorted door switch or a shorted relay on the control board.

You can see a help file on door switches here.

No! this is not normal, the light should only come on when it is cooking, the cause may be a defective door switch, the oven would need to be dis-assembled to test all the switches to find the faulty one.

1200 watt panasonic, power on but will not perform


Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Panasonic S943 microwave activates when door is opened. Light, Fan, and Turntable all come on when door is opened. Still cooks normally when door is closed.


I had exactly the same problem with Panasonic NN-S962. I found very useful technical guide on the following website: http://www.eletrodomesticosforum.com/es/cursos/horno_microondas/Inverter.pdf
In the troubleshooting table on pages 31-32 it correctly states that this problem is caused by shorted primary switch. The technical guide has diagrams and photos helping with locating primary switch. I ordered a replacement switch from Sears PartsDirect (part no.46-692286-3). However, it is a common Omron switch V-15G-3C25 or its replacement with 16A analog sold by Sears PartsDirect that may be purchased cheaper elsewhere. After I replaced the switch my microwave started working normally. It was the easiest fix ever. Took me more time to research the problem and find the right part than actually fix it. That's why I decided to post this solution to save time for those who experience similar problems (looks like a fairly common problem for Panasonic microwave ovens).

MICROWAVE TURNS ON WHEN DOOR IS OPENED.


This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Door switches are most often damaged by opening the door while it's cooking (instead of pressing Stop / Clear first) or food
/ grease debris in the switch.

Inside light is burned out.


The Sears parts Web site has a ton of helpful info on this model, including disassrembly help. Looks like a lot of the actual service manual online! You can also order parts there. Enter your whole model number NN-S567BAS at http://www3.sears.com/ (the 3 is correct) Terrific!
