Question

Refrigerator freon line has a leak how do i repair it?

Answer 1

You cant do it yourself without the knowledge, special tools, and EPA certification.

The cost of the repair is not going to be worth putting that into it unless it is under warranty.

Answer 2

HVAC Tech.: I have made such repairs with "J&B WELD" I let it set for 24 hours then recoat my patch.  Careful cleaning earns you extra hold. then the unit is ready to have a vaccuume pulled on it and recharged with whatever was the orignal charge. If you lost a lot of the oil it will need to be replaced. Careful not to put to much, there has to be room for the refrigerant. To much oil -it won't cool, to little it won't last. You will probably need a technican to do the recharge as that unit would not normally have charge ports.

Answer 3

just call a technician. You'll spend more on tools than what you are going to spend on reparing it.

Answer 4

junk it, its not worth it...all these guys say vaccuum the system, fill with freon...blah blah, its probably R-12 and if you can find some (because they don't make it anymore) it would cost you about 100$ an ounce and you probably need several ounces....furthermore, you probably dont have an ESCO license to obtain the equipment or the materials. Trust me...either junk it, or you'll pay for a tech to come repair it...it's not a do-it-yourself project..

Answer 5

Is it a copper leak or an aluminum leak? Copper will need to be braised using 15% silver solder and at least some map gas. An Oxy acetylene torch is better. For aluminum repairs you is gonna need some epoxy putty. The unit is going to have to be free of any pressure whatsoever and allowed to dry for at least 24 hours. Then the system will need to be vacuumed out for an hour or more. Negative 29 psi is ideal for vacuum pressure negative 26 psi or better is ideal. After vacuuming the system for at least an hour your should shut everything down and see if the  ice box does not loose it's vacuum. If the vacuum holds then move on to chrarging the ice box. Allow for freon to enter into the icebox sealed system and equalize. Turn the ice box on and  Proceed to charge the unit SLOWLY to 5 PSI on  the low side with R134a or freeze 12. If the low side compressor ear gets frosted over you have too much freon in there. Most domestic US refrigerators only hold 4 ounces of freon(1/3rd of a 12 oz can) If the compressor lugs down, liquid freon will plug up the flow. DO NOT OVERCHARGE THE UNIT!

Answer 6

you probably dont. first you need  to find the leak which requires special equipment then you have to reweld the line. a lot of leaks occur around the indoor coil and many times its best to condeman the evap and replace it. nobdy wants an old leaky evaperator.

if you hit the line with a lawn mower or something and its obvious where the leak is, well, you simply re-solder the copper then recharge the unit because all of the gas is gone.
