I have a dometic RM2193 refrig that does not work on 120v. I think the problem might be with one of the wires that came loose under the control panel, however, I want to be sure that I have the correct wires going to the correct prongs. If anyone has this type of fridge, can you tell me what color wires go to the 3 prongs under the control panel (also, there is one other prong set away from the other three that has no wire to it....is this correct.) I'm not an electrician so the wiring diagram on the last page of the manual is worthless. Here's a picture.
