|Dometic Refrigerator problem||Dave Wendel||12-30-15|
|I'm running our fridge on gas. The freezer is nice and cold but the refrigerator part is only 55 degrees at best. Because the freezer is normal, it leads me to believe that the flue isn't dirty. I've been moving the sensor on the fins up and down, but still not cooling below 55 degrees, even at night when it's cooler. Could my sensor be bad? I appreciate any feedback.|
Thanks in advance...Dave

|1ST High and as far to the right as possible on the fins is as cold as it will run.|
2nd to test if the sensor, called a thermistor in Dometic speak, unplug the thermistor at the board in back for 24 hrs. This will cause the fridge to run continuosly. If the fridge is in a mild climat, say below 80 F outside it should freeze water on this test.
3rd The spec for your fridge is likely 1 quart or liter of water from room temp to between 42 and 48 degrees F in 12 hours from a warm start. Most likely close to 48 degrees.
It is common for a failing cooling unit to have trouble acheiving Specified Temps. A corrosion blockage or leaking Amonia coolant.
If it will not cool to the specified temp in 12 hrs with thermistor unpluged Checkthe following first:
Is the burner in good condition and do you have an even blue flame?
Is the ventilation behind the fridge clear of blockages? Is the vent and fin areas clean and free of spider webs, cob webs, dead critters etc. All of these repaired here in our shop. The best one was the Rodent deposited Wheat on top of the fins at the top rear of the fridge.
If this doesn't fix it, start pricing Cooling Unit Repairsand replacement cooling units, I recomend an RV tech replace a cooling unit, the Amonia is dangerous!
