Domestic refrigerator not cooling

RV 101 question. We have the refrigerator on. The freezer got cold but the refrigerator didn't get real cold. The door was shut well and not continuously opened. Any ideas?

Also, when driving, what is the best way to keep the refrigerator running. If I remember correctly, if propane is off, the refrigerator does not run. I have been told to turn propane off to drive for safety reasons.

Thanks.....

First how long has the unit been running it can take a day or more for the refrigerator to get to temp after the freezer. If you have a gas/120 fridge then it will run on gas while you drive there are also 3 way units that will work on only 12 volt also.

Thanks Todd! We had it run all night. Is there a way it runs without the gas while driving meaning if we turn it on, it should run with the 12 volt from chassis battery and we can turn gas off. I am thinking it would give us the check light only when we shut down till we get ship power. If this is true, I had it on for a 6 hour drive and got no cold from it.

What model frig is it? Odds are you have a two way - runs on 120 vAC or LP gas. HOWEVER - the frig needs 12 volts for the logic/controller board.

If your on shore power, it should be running on 120. when you remove shore power, it should attempt to switch over and run on LP (if the switch is in AUTO)

It will make several attempts to light the LP burner, then give up and display an trouble light. The only way to reset the light is to turn the frig OFF for maybe 10 seconds, then turn it back on again. It will then see if it has 120 volts, if it doesn't it will again attempt to light the LP burner.

COOLING PROBLEM.

Make sure you actually have stuff in the frig when you start it up. We usually put a couple bottles of water in the freezer and a a half a dozen in the lower frig. This not only cools the water, but technically, gives the frig thermal mass to work against. (Lot more mass in water than there is air) so this will help get the thermal differential going which should help air flow inside the frig.

It takes a good day for the frig to get to temperature. ALSO - try to pre-cool stuff in your home frig first, if you can.

MANUALS

I wrote down the model numbers of all my appliances, downloaded and printed the manuals, then took the manuals to Staples Office supply and had them bind all the manuals into one book (probably about 75 pages). (cost about $4 for them to spiral bind with a nice clear cover.

We had a 3 way in our RPOD, and it only worked well when the ambient temperature was 72 or less. I traveled cross country last summer, and had to buy a seperate cooler to keep the critical items cold on the warm days. Had it checked out in Seattle, and they said it was fine (of course it was cooler there than in Kansas). BTW, we always traveled with the gas on. You are supposed to turn off the gas when filling up. I tried running on battery and noticed the battery would loose some of its charge on an all day drive.

We always kept the fridge going - 24/7. If on the road, we either had the gas on or the gen running. Kept it on shore power when stopped. Fridge kept everything icy cold the whole time we had it (5 years - traded it in last April). When we did trade, the inspector remarked how nice and cold the fridge was. Leaving the gas on while driving is not an issue, just be sure to turn off the fridge when fueling.

I am having the same problem with my Dometic model 2652. It has been running for almost a week and a half now with a temperature that will not go below 68 degrees. The freezer is at a steady six degrees. I have tried running it on electric as well as gas, and the same result each time. I also travel with the refrigerator in gas mode.

Check to see if the fridge is level. Place a level on the bottom of the freezer to check, not in fridge or on shelves.

A trick to help cool the fridge I use when starting it up for a trip is to put 2 or 3 two liter bottles of COLD soda in it. Some use a bowl of ice cubes in it to give it a head start.
