Dometic Gas/Electric Refrigerator Operation
Depending upon whether you are trying to utilize gas or electric, it will take up to four to six hours to reach normal operating temperature. While the newer gas/electric refrigerators are a bit less demanding regarding level, typically, the closer to level the refrigerator/coach is, the better the refrigerator performs.
If you are trying to operate on LP Gas, check to be sure that connections at the tanks are tight, and that both valves are open (particularly the one that the regulator arrow is pointing toward). Then, to check for good gas flow, light at least one burner on your range and observe the flame -- is it a strong blue with little yellow and minimal "hissing" or other noise? Sometimes, when on gas, it is necessary to allow the stove to run for a period of time to allow air in the pipes to escape and the LP Gas to find its normal level -- when the gas flame on the range top normalizes, it is a good time to try to start the refrigerator on Gas.
If you are trying to run the refrigerator on 120-volt AC, you can check to be sure that it is plugged into the outlet in the compartment or wired into the junction box. The box or outlet is typically visible when you open the exterior access panel for the refrigerator.
It is possible that the refrigerator may not operate on either LP Gas or 120-volt AC if 12-volt DC isn't connected if it is like many of the newer models with an electronic control board in which case the control board demands 12-volt DC in order to start refrigerator.
Good luck with your investigation!
