New here..... was looking for the control signal though. Different mfr/name but EXACT SAME BOARDS you pictured, hence my reply here (right down to the mechanical layout and wire colors in the pics. mine's a Haier) . My P.S. boards, as well as the dual controls on the door all work just fine. My issue is the control signal that comes from that smaller board, and send the signals to the p.s. to activate full power mode to chill. (two three pin wires that one each go the the p.s. boards. One pins is the V+ feed from the p.s. to power the controller and a gnd. The third is a feed back loop tap to the input of an opamp (the pin they say to short to test modes) But this is an analog control signal.

My issue is the control signal ...

Can you give us some more detail about what you mean by that? Do you know for certain that the cooler can run and cool?
