They never actually diagnosed it, I did. They just kept replacing things until they decided they couldn't actually fix it and sent a check. At no point did LG or the authorized center actually find a leak, or suggest that it might be leaking from the yoder loop. They would come out with their leak detection equipment (both sniffers and after the dryer replacement, a UV light to detect the dye) fail to find a leak, and just replace the next thing on the list. Which usually was a three trip process for each item they replaced with a few days/week or so while they ordered the part, and queued the work detail.

I had the yoder loop conversation with the tech on the last call when they came out to verify it was still broken/unfixable, and he basically said bypassing it wasn't possible, which is odd since other companies can.
