This is not a Frigidaire but I could not post the question without picking something and GE was not offered??????

GE model PFCS1NFYASS Does nothing. Control panel dead.

The light bulb attached to the control panel comes on. That’s it. Nothing on control panel is on. No fans, no cooling nothing. Where do I start? I can use a meter. I am a licensed Electrician but not a electronics technician. I have the tech. data sheet from the bottom of the unit and the parts list from GE.
