Question about Panasonic NN-T694SF Microwave Oven
The microwave was running for 2 minutes on high. There was a loud popping sound. Opened the door and it seemed normal. When the door closed the fan ,turntable and light came on. Could not stop it without unplugging it. When it is plugged back in the fan turntable and light starts immediately, and the display shows the welcome screen. the only button that works is the stop/reset, and when you press it the screen goes blank. Any help would be appreciated
is usually caused by either a bad door switch, a loose door switch
mount (which are pretty simple problems to fix) or occasionally a
problem on the control panel.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.
You can order Panasonic parts from Tritronics but if you only need a switch, you can order one from us for $5 postpaid.

Welcome to FixYa
The loud pop
sound is caused when either it is a bad fuse or the high voltage capacitor itself
has gone bad and needs replacement. As everything is working fine so the
problem seems to be either with the door switch or the high voltage capacitor
that is bad. Please check the door switch if that appears to be fine then to
replace the high voltage capacitor you'll have to take it apart completely. Please
get back to me if you have any other questions.
