SOURCE: Microwave won't work

F6 usually means a fault in the controller or keypad. You could try to unplug it for several minutes, then plug it back in. If it still fails, maybe you or a friend can disconnect the power cord, unplug the keypad strip internally, then plug the power cord back in and try it with the keypad still disconnected. If it does not fail again, you have a wet or shorted keypad and can dry it or order one. If it does fail again, the control board is bad. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: http://tinyurl.com/gv383 Sorry I didn't get to answer this before the bogus answer was posted. I've been tied up and away from the PC.

SOURCE: Microwave turning on by itself

Sounds like a relay is stuck/activated by something. Causes are power surges, mice shorting wires, spiders and such creating bridges across the contacts on the circuit board. Not a DIY project unless you have some electronics background and know what precautions to take while inside the case. There is enough juice in there to seriously injure or kill a person. Eric

Why microwave won't stop running unless door is open ?


Is it actually heating or just making noise and acting like it's heating? (put a cup of water inside and close the door.) IF it's actually heating, then you have a shorted relay on the main control board, and you will have to replace the board. IF it's just making noise like it's working, but it's not heating, then the problem is 1 of the door switches is not working right (it's either stuck open or stuck closed).

Sounds like a problem with the control panel. Further diagnostic testing would be required, however, as there can be other causes.

My nn-s963bf starts operating when door is opened


The electronics have lost their marbles. When a nuker door is opened the safety switch connected to the door is designed to turn the unit off and not on. You just better work fast when you put stuff in or take it out!!!!!!!

I'd check to make sure you don't have a door switch that isn't functioning properly. Also, might be a control panel or control panel interface issue.

It's probably the magnetron which some companies provide an 8 year warranty on for parts but you'd be responsible for labor. Unless you have an extended warranty, it's probably cheaper to buy a new one than to repair this one. I tried to look up your model number but doesn't seem accurate. Do a little research, there could be a known defect and the company may help even though it's out of warranty.

i think you have a welded controller, either a digital one or a mechanical one. microwave won't run unless you switch it to run. the door switches are safety switches to turn off the microwave once you open the door. if you have a digital controller, you could have a welded relay, if you have a mechanical timer, it could be a welded contact at the timer. another thing is that it should heat what ever you are heating. if it is not heating, check if it has a fuse and if it is busted. some fuse are installed to protect only the magnetron that is why the light and turn table are still running. if there is no fuse to the magnetron, then check the diode from the capacitor to the ground. it could be open. if not then you can have a bad magnetron. i hope i was able to help.
