Propane extension line for new fridge

Replacing my fridge this weekend. Of all the minor hurdles you'd expect replacing a 20+ year old unit with its comparable model, this is the only one I don't have an easy answer for.

My old fridge lined right up with the propane line, obviously, but this new one is probably 6" off. Going to an rv shop to have them install an all new, longer hard line isn't in the cards any time soon financially.

I see various pigtails for sale online. Is it as simple as buying a male to female 3/8" flexible pigtail? Like this? Of course 36" is too long, but I want to make sure the male and female connections will actually connect to my hard propane line (flared end) and the fridge connection. Or is buying 6-7" of hard line, fittings and flaring tool my only option?

Go to your propane dealer and have them make it for you. RV places seam to way to high priced and the Propane dealer will have the experts.

Thanks. I wanted to but on Sunday, specialty shops are closed. And I'm impatient when my fridge is down...

In the meantime I bought this. Assuming it works, I should be set. If not, then I'll hit the propane shop on Monday.

I think you have done OK. One thing that I would be sure to do is to mount a block under it and secure the pipe to the block so it will never flex. You also need to make absolutely sure there is no leak.

Alright, thanks. Hopefully there's a place on the back of the fridge I can secure it. We'll see. Either way I'll make sure it's secure.

Borrowing a cutter and flare tool tomorrow, so we'll see how it goes. At least I'm under $10 for this part of it so far...

Well, that worked. My old fridge had a nice, long, straight shot to the propane connection, which made it easy. The new fridge, for some reason, lined the connection up pointing right at the side of the electrical panel, with about 5" of space between them. Not conducive at all to easy propane line access. Oh well.

The 2351 certainly is a modern direct replacement for my 2301, but man, without doing major cabinet renovations, it only just fits.

Anyway, it's cooling now. Vents are off so that I can keep an eye on things, but once I'm convinced it's really working, and not going to burn my camper down, I'll close the vents and see how well it cools in 90-degree weather. I don't expect night and day difference from my old fridge, but I do expect a noticeable one.

This fridge came with a factory-installed fan, pointing up toward the fins. It's currently 85 degrees outside, the fan I installed in my upper vent (thermostat controlled) is on, but the new fan is not.

Anyone have experience with these fans that come installed on newer fridges? I would think this is the weather that it's needed...

Gotcha, thanks Joe. I guess my point was, if at 85 degrees it's not needed, when is it needed? You know? Assuming it's on a thermostat. But I'll admit I'm not used to a fridge with a computer. If it's not a simple matter of a certain trigger air temp back there turning it on, but some interface with the internal temp and the fridges needs, then I'll stop even thinking about it. Truth is, it's cooling just fine, with or without the fan. Not having control of the temperature is still very strange for me...I'm used to watching the internal temp really close and constantly adjusting the knob settings. Very hard for me to just do nothing...but I think I'm going to like it once I get used to it!

So far, unless I open too often, it has no problem cooling in 80-90 degree temps. That's a huge improvement from my old fridge. With my old fridge, even if I didn't open it once, it would start losing the momentum it built overnight, sometime around 2-5pm depending on how hot a day it was. It couldn't keep up with temps over 80, it just relied on decent insulation to hold what built during the cool night and morning.

It was weird for me also, my fan cycles a odd times whether it's hot or cold outside
