Re: Refrigerator not cooling on the road

I find the opposite with the 5cf. fridge in my 5.0 ......... I wonder why the dial goes past 4! My first fridge froze everything on setting 1 and was replaced so when I got the new one home I did a lot of testing on it using a mercury min. and max. thermometer while it was sitting on the driveway.

The following is with the fridge empty:

With outside temps of 17C (63F) at night and 33C (91F) during the day I had fridge readings of minus 3C (27F) at night and 5C (41F) during the day with it set to #4

When the outside temps dropped to 15C (59F) at night and 28C (82F) during the day this same setting (#4) gave me fridge readings of minus 7C (19F) at night and minus 2 (28F) during the day while the #3 setting gave me 1C (34F) at night and 4C (39F) during the day at the same outside temps. We had a short spell of 35C (95F) weather and the fridge temp never went over 5C (41F) when set at #4.

I find I have to set the fridge at #2 1/2 to #3 to stop freezing the contents and only turn it up to #4 if the temp goes over 30C (86F)

I'm quite happy with this as I'd rather have ice in my beer than drink it warm.

I now have a small cooler in the pantry and all the veggies go in there.

I always drive with the fridge on propane and have never experienced a warm fridge ....... touch wood.

Re: Refrigerator not cooling on the road

I took a trip from Washington to Wisconsin in July. On the way out our fridge would get really warm when driving and would cool when parked. On the return trip I tried closing the overhead vent in the trailer, just to try something. This seemed to help quite a bit. The temps did rise when on the highway but there was at least a chill in the fridge when we stopped. There may be something to the comment about pulling a vacuum in the trailer and it affecting the fridge temps. I do not have enough data to be sure but if your fridge is getting really warm when driving try closing up the trailer completly when traveling.

Re: Refrigerator not cooling on the road

tao, I am not surprised that it helped to close up the trailer, as you found. People often think that in hot weather, they should open their (house) windows during the day. In fact, they should be closed all day and only open at night when the air is cooler. I would think that the same applies to the trailer. The trailer is being filled with hot air when something is left open in such weather.

We started this thread back in July, 2012, telling how our refrigerator (Dometic 5 cf in an Escape 19) was not cooling during drives, but worked fine when parked. Since that post we took another 4-week trip in moderate to cool temperatures, and that trip again showed that the refrigerator didn't work at all when at highway speeds. We took detailed notes of the refrigerator temperatures for several days, and then compiled the data into a table, which proved that no cooling took place while driving.

After that trip, we took the 19 for service at an authorized Dometic repair center. The repair center consulted with Dometic on the phone and they sent a fan and baffle to install in the space behind the refrigerator. The fan operates on a thermostat and has an on-off switch on the left side of the refrigerator (over the bed) for enabling the fan to operate. The switch is labelled "refrigerator fan switch" which leads us to believe Dometic has repeatedly seen the need for this switch and fan. The Dometic baffle is somewhere near the top back of the refrigerator. We will not be able to conclusively prove the success or failure of the new fan and baffle system until warm weather, when their purpose is to move more air across the cooling coil than occurs naturally.

Rease told us that he consulted with a Dometic rep who approved the configuration of the 19 with this Dometic refrigerator, but after the problem we've had, it seems like other owners (at least of 19s) should be monitoring their refrigerator temperatures during drives to be sure they are really cooling. The problem we've had is apparently not the refrigerator itself, but the improper air flow behind the refrigerator when the camper is in motion.

Another modification made by our repair man was that he used sealant behind the upper vent cover when re-installing it. He was surprised this was not part of the camper as built, and he believes it is important to keep water from leaking into the cavity behind the refrigerator.

You're lucky you didn't see any blue or red flashing lights either!

rvomaha ,
When you had the exterior fridge grills off your trailer did you ever see any sign of water leaking into the cavity behind the refrigerator?

One a side note, does rain water penetrate your RV cover? I have never owned one before and was curious. I sure hope this recent fix does the trick for you.

Signs of water leaking into the cavity? No.

Does water penetrate our RV cover? Yes.

That is weird. I have never noticed any issue in our trailer. I will do a closer check next summer to be sure though.

It would be very helpful to everyone else reading this thread that in your response, you mention the model or type of refer you have in your unit, there are about 3-4 different sizes being used now by Escape and if we want to determine if it is a specific unit problem or a install issue, knowing the refer and your trailer model would be very beneficial. Thanks...

Our refrigerator is the Dometic RM 2510, which is the 5 cubic foot size. Our trailer is an Escape 19, model year 2012.
