How in the F*#k do I fix this???
« on: January 29, 2014, 05:57:36 PM »

I scored a fridge at lowes on Sunday.  Brand new whirlpool top/bottom reg $849 for $100 as a non working unit. Found no refrigerant in system and found a leak at the pen point in the picture attached.It's on the back of the line. Any quick fix here? JB weld?

Thanks for the advice. One last question: how should I break the line without pinching it?

Aggie, if you're going to make domestic refrigeration a practice, I'd buy a roll of cap tube from you refrigeration supply house and practice various bends, welds, cuts etc. It's one of the most difficult joints if you don't know what to do.

Update, I used low heat and 15% silver brazing rod and sealed the leak up. Pressured up with nitrogen 100 psi. Held over night. Vacuum and charge - all good. Already have it sold for $650 lol. Not bad for a hundred dollar lowes special. Thanks everyone who responded!

If the hole was actually in the cap tube then it sounds like you got very luck with the repair.

If I would have tried something like that chances are the capillary tube would have sucked the solder inside like a wick and plugged it up.

I would have pulled it out, cut it back and then soldered it as Larry suggested.
