Fridge



Dometic Temperature

7:30am - Yesterday, the temperature of Scampy's Dometic fridge climbed to 52℉ during the afternoon. It got up to around 90℉ here at Lone Wolf.

A lot of my attention has been directed toward the Dometic recently. This morning, I decided not to be concerned so much about the fridge anymore. There are foods that can be stored without refrigeration. Eggs and bread, for example. Also, buying foods that I will eat that day eliminates my need for a cool fridge.

When the Dometic is cooling OK, I'll store perishables in it. When the Dometic is cooling poorly [because of high outside temperature], I won't store perishables.


10:30am - New fridge vent cover
Yesterday we Blogged to you about our fabricated new fridge vent cover. Before this vent cover was painted, it was put in place and 'drive-tested' to learn how it would perform.

We were all very surprised to find that the tiny fridge burner flame stayed lit when we drove Scampy around. The fridge burner flame never did that before! It always went out.

The conclusion was, that this new vent cover prevented outside air from moving thru the Dometic's lower area. At this point, we do not know if the new vent cover will cause the Dometic a problem. It could be that the Dometic's temperature could go up with this cover in place.

  1. Hi George, please note that farm fresh do not need refrigeration, however commercially produced eggs have gone through a process that has destroyed the eggs natural protections and therefore DO need refrigeration. Happy camping!

    1. Hi Tom,

      Thank you for that warning!

      A dozen eggs for me should be consumed before 10-days.

  2. Are you hooked into electric for the Dometic or are you hooked into your propane tank? For a quick cool down of our Dometic, we use both electric and propane simultaneously. When the temperature hits 90 degrees outside, you might try that and not open Dometic until temperature outside has abated toward the evening part of the day.

    1. P.S. Also, we have put two small milk jugs in the Dometic with frozen water in the jugs.

    2. Hi Dee,

      Only propane. 12 volts DC uses too much battery power. Scampy almost never has access to shore power.

      This morning Dometic's temperature was at 30℉. So the fridge is working OK. Just a challenge to be at desired fridge temp when it is really hot outside.

  3. Your absorption refrigerator is dependent on air flow over the coils on the rear of the refrigerator. Perhaps your newly fabricated vent cover restricts the air flow too much? That's my guess as to the higher than normal inside temps.

    1. Hi Tooth,

      I was thinking the same thing when I wrote my Blog.

  4. When we were RVing in Mexico I added a small 12 volt computer case fan to the back of the refrigerator compartment above the coils. It drew outside air through the vent cover, up through the coils and out the roof vent. These fans use hardly any power but move quite a bit of air. Just connect it to an easily source of 12 volts at the back if the fridge. Easy job.

    1. Hi Croft,

      I believe that I used a fan with MsTioga.

  5. George you have completely blocked the air with the new vent cover. The fridge relies on convection pulling in cooler air through the bottom vent and out the top, so it's no surpfise that the fridge is not cooling

    1. Hi Matt,

      Yes, your are correct. I came to the same conclusion yesterday and removed that new vent cover.

  6. George, I don't understand how your fridge keeps being blown out by the wind. We always travel with ours on gas and have never had it blow out. I just don't get it.

    1. Hi Croft,

      It may be, that the Dometic fridge that is used with Scampy has some kind of defect that causes the burner flame to blow out. This "blow-out" only happens when Scampy is moving.

    Had the same problem and my fix was to attach to the inside of the vent cover a washable furnace air filter. Had to make some adjustments to the filter so it would fit. Many years and a bunch of miles .. no more problem.
