Dometic Refrigerator Tips
Hi Eric:
My apology, I had inadvertently over looked this E-mail. The original fan does or did have a thermostat in line with the 12 vdc power and was set to be on at 90 F and off at 70 ish F. When I replaced my fan, the large 12 vdc fans found at truck stops or RV parts, I took the thermostat out of it and went directly to the operator controlled switch on the panel. Curt's solution worked for him as well, and not a bad one. I just like larger fans pushing more air through the coils and out the top of the stack. Either way, air is moving and that is the preferred thing. I did an experiment out in Phoenix (119 F in the shade) when visiting our Daughter. I took and umbrella and made a shade for the out side compartment and it did help cool it down as well. Was going to put the smallest ZipDee, like over the windows, over the refer out side compartment to match the rest of the Coach. But that is an extreme, just thought it a good idea, still do. Glad your refer reset for you. The fridge temps should be in the area of 36 to 39F in the main box and 6 to 9 degrees F in the freezer, this is the normal temps.
