Hi, I have a Panasonic microwave oven, model NN-S215MF/WF. The problem is that it has suddenly stopped heating... the light goes on, the plate goes round but no warming/ heating. I just want to know...

If you have 15 minutes and a screwdriver (don't know which type is used on your unit), I would unplug from the AC, remove the housing so you can see the floor of the frame and the control devices, look for a fuse to replace, keeping your hands and fingers clear of any bare terminals. This unit may have two fuses; one for the high voltage circuit for the magnetron, another for the other parts such as the control circuitry. The first fuse will be 15-20 amperes, the second much lower. If the fuses are visible and close to each other, make sure you know which fuse belongs where; they will have much different ratings for current.

Since the light and turntable are working, the lower value fuse is obviously OK, so if you find two fuses, remove and replace the higher value fuse.
If you do this, turn it on and the fuse blows again, then it is time to replace the unit with a new one since the other parts that can fail require a little technical background and a multimeter. The cost of having it done by a pro will likely amount to more than the unit is still worth.

How do I remove the sensor inverter on the Panasonic NN-S96OWA ?

That's a misnomer.

And oven may have an inverter and it may have a sensor (usually either a heat sensor or humidity sensor).
