Sparks from upper left vent area

Hello! My GE microwave has recently started to spark and crackle (the noise) behind the vent on the upper left hand side. The sparks are not in the food compartment of the microwave, and the microwave is still heating properly. Any idea what what is wrong and how to fix it? Thanks!

Sparks usually indicate a loose connection or a breakdown in the insulation of wiring or components allowing the current to arc between two areas of different voltage potential.

Be extremely careful there are high and lethal voltages inside a microwave oven.

I suggest that If you don't know what you are doing that you turn off and unplug the microwave and do not use it until it has been checked out by an expert.
