1. Any code showing on the eyebrow?
2. Is the fridge turned ON..??
3. Use a meter, or any lamp if you don't have a meter and ensure 120VAC to the receptacle in the outside compartment.
4. On the small black box inside the outside compartment you'll see two wires at the bottom, a black one and a white one. The black one is 12VDC and the white is a ground. Do you have 12VDC at the black wire?
Do these four simple tests and let us know the results, then we can go further....Dennis
