I think your problem as you described it is more with the wire harness connections rather than the soldered components on the board it self. I have always used an eraser to clean that green corrosion off of my terminals. I had a similar problem on my connector and cleaned it this way. The only green stuff I see from your pictures is right above the 16 pin connector. I am assuming they were taken after you cleaned the board. Was that green stuff over the whole board or just were we see it now?
No the refrigerator is now working the problem afaik is only with the green stuff (corrosion) on the pcb.
Yes those pics are after I cleaned the PCB. I'm not able to get an eraser near the green stuff. I'm thinking of using some Clorox, perhaps some navel jelly and perhaps try some vinegar and scrub some more with a toothbrush. However it really requires a stiffer brush so I'll try and find a brush with fine bristles made from metal such as copper or other.
Possibly I can clean the green stuff with a fine metal pic.
I'm fairly certain there's no problem with the wiring as most of the time the refrig works, the problem usually only occurs during and after a rain storm which usually only occurs once or twice a year.
