Kitchenaid KRFF305ESS00 refrigerant lines going into body NOT to evaporator

Refrigerator
Model: KRFF305ESS00
Serial: K65014902

Long story short I pressurized the system to 100 psi with argon (I’m a welder so it’s what I have on hand). I can hear the leak coming from the front of the refrigerator when I put my ear against the bottom shelf where the door refrigerator door screws into.

I started to cut out the foam in the back to trace the lines one goes to the left and the other goes straight. It’s going to be a pain to cutout the foam so I wanted to get some opinion on how to get to whatever is at the end of those lines that’s leaking.

What I’ve done so far:

  1. Soap test everything accessible at 3 psi - no leaks
    [list=1]
  2. Compressor lines
  3. Evaporator lines
  4. Condenser and lines
  • Bought the service manual/parts list online ($16)
    It only shows the compressor and filter dryer… these two lines I’m interested in are omiited!
  • Searched online for diagrams/posts/etc that describe the internals of what the refrigerator might have outside the condensor/evap inside the body…
  • Cut out a part of the back panel to follow the line back to the leak (where I currently am)
  • Signed up at AppliancePartsPros and did some searching for my topic - No real results but might be my search terms…
  • Posted this topic hear to see if someone knows what those lines are going to

Images of the lines I’m referencing below.

If you can identify them and let me know the easiest way to get to the end I would highly appreciate it. Thanks!

Update. Turns out to the the Yoder loop. Not worth the time to fix since it will damage the door. There’s an alternative where you get a small heater wire and run it through the lineset.

Going to look into that it might just let it run wild without one. I’ll update this in a few months with the solution I went with.
