Microwave control panel failed NCVT test

[lafla]

I always check outside and inside with a non-contact voltage tester after powering up before either of us, or the dog, gets inside the Airstream. Everything is always fine EXCEPT for the control panel face on the convection microwave. Has anyone experienced this issue? Any advice on how to approach? I'm assuming I need to remove the microwave and then the front panel to see if any frayed or loose wiring, correct? Thanks for any input.

Yes, pull MW. There is a standard plug/receptacle.

Plug another device like a lamp in the outlet or use Volt meter (VOM).

Chances are you can check the GFCI FIRST
