Yes it can, but you are going to need special equipment. Such as a vacuum pump to remove the air, Touch to repair the hole or replace the evaporator that you poked the hole in. Along with a set of gauges and refrigerant. This is not a job for the average DIY'er and even as a pro I only repair sealed systems (leaks, compressor, etc..) if they are under warranty because it's a time consuming and costly job other wise. If the refrigerator has any age on it then you may want to start shopping around for a new one.
You can fix it. You would first need to find the leak and repair it. Then your would need to evacuate the air out of the sealed system to prevent ice blockage. Then you would need to slowly add gas to the system till it reaches a maximum of 5PSI no more. Then you oughta be good.
This is likely a manual defrost freezer, which means you have to remove the food, unplug the unit, and let the ice melt on its own. Do not, and i repeat, DO NOT poke the ice away from the walls. I guarantee if you poke the ice away from the wall, you'll poke a hole in the wall, and force yourself to buy a new freezer.
SLOWER IS SAFER. put some boiling water, in the pot, inside the freezer, or use a hair dryer.
If this freezer is running all of the time and only freezing the walls at the top inside it is a good chance there is deteriation in the piping in the walls eg (rusty pipes) letting the refridgerant escape (common fault) with chest freezers.If it is more than 7 years old it would be advisable to replace it as the repair would probably cost 3 quarters of replacement price.Hope this helps. Kind Regards.
Does your model have independent thermostats for the fridge & freezer???
If not, could be that you will need to change the Thermostat.
These are not expensive - around £10 if you buy on the Internet.
Easy to fit yourself...just turn off the power, remove the power plug from the wall, then unscrew the 'stat unit from inside near the top of the fridge (some are attached to the interior light) and remove the screw holding the thermostat tube to the rear wall.
Often the thermostat gets a small hole somewhere in the long tube, which then lets all the gas escape, making the stat useless.
You can see these small holes in the pipe if you use a magnifying eyeglass, like the kind Jewellers use.
not very easily. Most freezers have the evaporator and condenser inside the wall of the cabinet and you cannot access them. If the puncture is in the condenser you can put in an exterior condenser however the parts break down for your model does not offer this option (:
Short answer no. The only way to repair it would be to strip back to the pipe cut the broken section out and replace it. If the broken section is aluminium this is even harder to correct. The system would then need to be vacd and recharged. Bearing in mind the evaporator which you punctured is on the low side you have probably got oil contamination which could mean the compressor could fail in a relatively short space of time. All of which means you are probably looking at a new unit. You can get this confirmed by explaining the leak to a local fridge guy. In my opinion it would cost more to repair than to replace. Hope this is of some help. PS this happens a LOT and is normally a fatal wound.
