The fuse will be a white or gray ceramic fuse, and you really can't tell if it's blown without actually measuring it. If a new fuse blows when you hit START, you probably have a shorted high voltage capacitor. If you have replaced the fuse and still have no display, then it sounds like there's a problem on the control board. The control board has a built-in surge protector which can short (and smoke) and when it does, it will cut the power to the control board, but not blow the fuse. We repair these nationwide for only $39.95 postpaid. If you or a friend want to check it out or send the control unit in for serivce, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

Did you recently have trouble with the cooktop lights?

Sometimes when the cooktop lights blow or are inserted or removed while the oven is still plugged in, the filaments can short, causing a surge that damages the controller.

They can be repaired. More details here.

Sounds like a blown fuse. Carefully remove the cover, and the fuse in directly behind the power cord on the top. Radioshack sells 15A ceramic replacements.

In all likelihood the mangnetron is failed or failing, or perhaps even the Power Supply is faulty. You need to have it serviced by a reputable service centre/man.
Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one

most microwaves do have an internal ceramic fuse either 15 amp or 20 amp the cover has to come off to locate it usually at the top just behind the control board. do not touch the high voltage capacitor as it holds a charge even when the unit is unplugged.

Panasonic Microwave NN-S935BF turntable and light do not work. Microwave still works. Bulb and turntable motor okay. No power to light or turntable. Any ideas?


Your description seems to be confusing turntable and light do not work
Bulb and motor OK
No power to light or turntable

Which is it?

They could be separate incidents. The drive motor could be fused and the globe just blew its life away..
