Does your Dometic refrigerator have frost on the fins?

I use a small 2 D cell fan. It helps, but in humid weather, nothing will stop the fins from frosting up, so I just empty it to a cooler, let the slobber tube do the work from there.

Even with an added 12v fan (for a photo, check near the bottom of the link to my trailer modifications), I have to defrost my refrigerator fins about once a month in hot, humid weather. It is a single door, small (5 cu ft) Dometic RM2510 manual - no defrost switch (or any electronics other than the igniter, for that mater).

Mine will frost up when I have to open the fridge door in Midwest or Great Plains summers, or any time of year in mid-South or on the Gulf Coast. Was 88F today with dewpoint 84, my glasses fogged up stepping out of 80 degree house.

On the other hand, no frost in high desert of Colorado Plateau, most of the time, but it can get humid during autumn. No frost ariund Phoenix most of the time.

So whether or not fridge frosts up will depend on how much moist air you let in.

A friend of ours turned us on to the fridge-fix as we had many of the issues talked about here. Our least favorite was all the ice that would accumulate on the cooling fins. The RV dealership that we bought our coach from told us to "just carry a cooler with you to put your food in while you defrost". ?? And where exactly are we supposed to carry the cooler when we are not using it?

First we tried the battery operated fans, but the batteries were so expensive that we threw it away after 2 refills. Rechargables were just pitiful too...We had 2 of the little fans from ebay, but the first one lasted 6 weeks, and the second about 3 months.

We usually do not post about stuff like this, but the guy and his family that build these are some very helpful folks. We got ours at their website. It was worth every penny and then some.

I bought and installed one of those. Made my temp go up 1*. Figured it was working and keeping the whole unit to an equal temp through out the fridge and just not at the temp probe. Very easy to install and ours has a toggle switch to shut it off if you want too.

Some of the problem seen when refrigerator section fins ice up is liquids freezing in the box.

Thermisor malfunctions and refrigerator defaults to cooling cycle "always " on. On older models default was "off ".

We just turn the refrigerator off for about 4 hours until ice melts from fins and restart the refrigerator. Food will be fine and computer resents for normal operation.

Wiind and extreme temperature changes can cause "default " for unit.

I might see about that -- if it requires no wire splicing, then that will be of a great help. I use a 4 D powered fan already, but having the ability to not worry about replacing batteries in yet another device makes the ebay one look good.

Doesn't require any splicing - clip on the back attaches to the fins which acts as ground and you squeeze another wire into light circuit for power. I had to play around with it a bit to find the right circuit so that the fan ran when the fridge door was closed but that's probably because I never read instructions.

In Florida, I end up defrosting evey couple of weeks due to the high humidity. As mentioned in a earlier post, I also use a hair dryer and I'm done in a few minnutes

'Refrigerator' is the term used for an appliance that has a freezer section and a fridge section.

Sometimes due to high humidity the fins in the fridge section will frost up.

If you use the 'refrigerator' enough.....the freezer section will need de-frosting.

We de-frost the freezer 3-4 times a year as our refrigerator is on continuously.
We have had to clear the frost off the fins in fridge section only couple of times.
