Freezer puncture.  I punctured the liner to the freezer, creating a slight hole that emitted a vapor (presumably freon).  Must I repair it?  How do I repair it?  

NO, all the cold for the frig comes from the freezer. No separate cooling coil for the frig. You probably just killed your frig. I've never been able to repair a puncture line and recharge.

Is the freezer/ refirdge still working? If everything is still working, then the puncture did not cause damage to any great extent. Just place a piece of aluminum duct tape of the puncture hole. You can purchase the tape in a hardware store or Home Depot/Lowes, in the plumbing, heating dept. If the refridge is not working, then there is a major repair to be done.

Simply no. Sounds like a line in the cabinet has been punctured. No repair for that.

The hole can most likely be fixed with epoxy and a filter drier added to the refrigerator by an experienced refrigerator technician but the problem involved will be the cost to have the repair done. It would be less expensive to replace the refrigerator, Thanks Sea Breeze

No, the fridge will not get cold any more. The coolant goes to the coils in the freezer. The fridge takes a small amount of cold air from the freezer to lower its temperature.

I am sorry to say that unless you can find a way to repair the puncture and refill the system with freon, you are going to have to buy another refrigerator.

UUUUUUUgh....not sure....
if you punctured the part that has the freon zig zagging through it and allowed the freon gas to escape then...nope...it will no longer work and it may cost quite a bit to get it repaired.....but...if you are lucky you may have only punctured the covering and not got into the part with the freon...turn it on and see how lucky you are.

You punctured the aluminum evaporator . In the many years I've been in refrigeration , I have yet to find any way to patch a hole in the evaporator . I've used epoxy , solder , and all different advertised ways to try to patch aluminum . Nothing worked ( for long anyway ) . My suggestion would be to buy another refrig . You will be wasting time and money trying to " fix " this problem . To repair it yourself , you have to have a license to buy R12 , maybe you can buy R134A without a license , you have to look on the " modell , serial number tak to see which it uses and how much to use . Also , the system has to evacuated ( all air removed from the lines ) . Do you have a vacuum pump ? You have to buy a solder on connector ( or saddle valve which WILL leak eventually unless you get a solder on valve ) which will connect to the larger tubing on the compressor or use the access line already on the compressor but is pinched off . Do you have guages for the refrigerant type you need to use ? Once you have these things , reply back and myself or someone else will help you procede .

no sorry to tell you this type of problem is not worth repairing

i will give u an experience
if u can see that tiny puncture then u can fix it.
how? well take a 100 grit sand paper and slowly rough the punctured hole on the side of the hole approx 1 inch around it.clean it with a clean cloth. next take some petroleum ether soak a tissue in ththat and with the ether moist towel wipe the area and the hole nicely .now buy fro the market aluminium epoxy tubes. mix a little bit of the epoxy in a i:1 rratio and apply a coating of this stuff on and around the just cleaned hole.After about 12 hours the puncture is repaired now dont touch it.
Take the fridge to a professional refrigerant filling person who has experience in filling gas. he will vacuum the system and remove any ingress of moisture and then begin filling gas. your fridge will be good as new after this job

you have to bring it for repair.
the repair that they would do if they know how to is to weld the puncture hole by aluminum brazing , they may want to check the oil in the compressor in order to be sure that no water have been sucked by the compressor from the hole in the evaporator.

evacuate the system and charge it with the right amount of the correct refrigerant.

tnx 4 using fixya,
