RV Fridges in Cold Weather

RV fridges aren’t the same as household fridges. RV fridges are cooled thanks to evaporated ammonia that mixes with hydrogen to absorb the surrounding warm air, hence why they are called absorption refrigerators.

I really like my RV fridge because it runs on propane and very little electricity. It is very economical to run and its size is perfect for me.

The problem with absorption fridges, though, is that they don’t like extreme temperatures. That means that when it’s super hot out, the beer in the fridge is tepid and the freezer can’t make ice cubes.

In winter, in temperatures below about -10C/14F, it gets too cold for absorption fridges to work efficiently. In my case, no matter what temperature setting I use, as deep colds set in, my freezer edges closer and closer to the freezing point and the fridge stays a few degrees below the freezing mark.

This means that I have to manage my food stocks carefully. I had a bit of loss after the first big cold snap caught me by surprise, I can’t stock up on the rare good meat or frozen food deals I find, and anything that goes into the fridge is very likely going to freeze. It’s not a huge deal as I have to go to down at least once a week for propane anyway, but it’s something to keep in mind.

I’ve heard horror stories of fridges being killed by a brutal cold spell, but I like to think these fridges are hardier than that as long as you don’t continually abuse them. My fridge panel is sheltered from direct wind and snow, which does help in making me less twitchy about this. I’d recommend finding a way to shelter your vent if it’s exposed to the elements (do not block it off, though, as that would be a fire hazard!).

As soon as we get a warm up, the fridge and freezer work normally again, so that’s another reason I’m not too concerned. This is just another one of those cold weather RVing challenges and it’s definitely not the worst one I’ve encountered!

Not In the Mood to Drive

I just renewed for a third night here at Dakota Magic. If I really just wasn’t in the mood to drive, I would have gone anyway because I know that that’s just an excuse for not wanting to face the border crossing.

But I’m being really productive and making good use of my FHU, so I can justify another night. This morning, I defrosted the freezer and washed it and the fridge, then made an inventory of the food on board. I found bacon! It will be demolished shortly when I go make lunch. 🙂

It looks like it might rain, but if it doesn’t, the next project is the cab.

Besides that, I need to put away yesterday’s laundry (almost dry, YAY), wash out Neelix’s litter box, and then I’ll be good to go. There’s really nothing to do now to prepare for the border besides making sure I don’t have any illegal food on board, have a full alcohol inventory (one Texas beer that I am saving for the first crazy hot summer day), and that I know how much I need to declare.

I hope internet in Saskatchewan will be decent (although I will settle for existent). I get a very low signal in North Dakota, so I keep getting disconnected. I might not have found the connection in San Antonio to be so bad had I remembered my online experience in North Dakota last spring.

Fridge on 120V Power Update

Since leaving the beach, I had problems with my fridge set to the AC (shore/120V power), both on 30A at an RV park and 15A in a driveway.

I was really short on propane in Shawnee and was growing weary of just how quickly I go through the gas when the fridge is running off it, so I decided it was time to do something about it.

I started by going back over some of my electrical posts from the beach because I had a niggle at the back of my mind. And then I found my post about the salt water corrosion on my battery terminals.

Doh. I went out and cleaned the fridge terminals and connections with a scrubbie pad and an eraser, then turned the fridge on to shore power. No problem in Shawnee on 30A. And no problem in Wichita on 15A. My fridge is also running colder on a lower setting than it was before.

Salt water is evil! 🙂
