The older Bigfoot
fridge installs were, I think, even worse than the install in my 91. Before replacing the fridge, check out the install manuals for your fridge or similar fridges.
Chances are, if you install a brand new fridge into that same space, you'll have the same issues. There are clearance requirements for the top, sides and back of the fridge. With the way Bigfoot
installed mine, there was way too much space between the back of the fridge and the wall of the camper, so there was too much space for air to flow, and it wasn't flowing over the coils as well as it should. Then there was around 2" of space on either side of the fridge, allowing heat to collect and get stuck. Then there was a space right at the top, where the upper vent is, that allowed air to be trapped.
Add all that to the very restrictive vent covers, and it's a wonder these fridges cool at all!
What I did, and what you should do before spending hundreds of dollars:
Install baffles at the back of the fridge. These somehow attach to the camper wall, filling the gap between it and the fridge coils, forcing the upwelling air to go through the coils instead of around them.
Fill the gaps on the side of the fridge with insulation.
Use the same thin piece of flexible sheet metal you used for the baffle to create a ramp in the upper rear compartment, at the upper vent, to coax the air out of the vent instead of getting trapped in the box-shaped area.
Install a fan in the upper compartment, blowing air out of the upper vent. I went as far as to cut a hole in the upper vent so the fan could blow straight out, unobstructed, and it made a huge difference.
I also take off the bottom vent cover when it gets into the 80s. That also makes a big difference.
Another thing to check before spending a bunch of money on a new fridge is the propane
pressure at the fridge.
is a long, rambling thread, but everything you need to know about getting your fridge compartment set up correctly is in this thread.
You will not have a functional fridge if the compartment in you camper isn't set up correctly, no matter how much you spend on it.
Being unsure of your experience, I'll say this: an RV absorption fridge is a very finicky thing and they take a lot of work, even when they're working well. You need to constantly adjust the temp and be very careful about opening the door, making sure the door seal is sealing, not parking with the vents in the hot sun, etc. They aren't like a household fridge that just works
, without constant attention.
