What have you tried so far?

I trouble shooter all major components (compressor, Coil, evaporator, defrost heater, fans, etc). Freezer still doesn’t get cold. I applied a pin valve to the suction side copper tubbing and recharged the system. As system got full, I could hear a hissing sound so I used my torch to locate the source of the leak. It was leaking quite a bit along with a liquid. Maybe oil. My question is can the split section were the leak is be fixed? Can I just cut out the section and braze in a piece? Or do I need to replace the whole suction tube. Either way – how is that done?

Hello
Yes, You will need to get a reclaimer and reclaiming tank along with a heat shield. See all three links below. No, you will not need to add any oil. Do not add any oil. The small amount of oil that dripped out will not matter.

Hello
You can cut out the bad piece of copper tubing and braise in a new piece of copper tubing . If its 5/16 or 1/4 inch you can buy couplings so they have an exact fit. Just make sure you use sand paper to make sure the fittings are clean before braising. See video link below of braising samples.

  • Will I need a heat shield? How do I evacuate the remaining gas before refilling with R134a? the leak being as big as it is. (Approx 2” tear) it seems that all the gas’s is already gone but there’s oil that’s also dripping out. I’m assuming it’s oil to lubricate the compressor. Do I need to add oil, if so how? Lastly, when I go to braze the joints, what precautions should I take? Will the oil ignite?
