OK just an update.
OK the only thing left seems to be the eyebrow panel on the front of the fridge. A trip to YouTube showed me how to get to it. I opened it up and it was quite dirty. I gave it a clean up with contact cleaner. Still does not work tho.
Thinking back on this, I have not been able to set the temp on the fridge, I could cycle thru only some of the temp settings but no matter where I set it, it would revert to setting: 5. Maybe that was an early sign of trouble.
So I suspect either that board or the membrane switches which I don't see a way to get to so far. There is only a ribbon cable and I don't see any obvious test points.
Any suggestions?
