I have problems with this coolers in my boat? Changed the Dwyer control units but still unable to control and operate them? The port only cools to freezing, the aft doesnt cool at all. Aparently there are codes that the Dwyer units needs to be set at. The default code for this controls is 0. Can anybody give me a hint on how to proceed? The refrigeration portion of the system works ok.
Please advice
