Question about Liebherr K 4260 Refrigerator
Only a portion of area of the frigo back panel, next to the fan, is full of snow/ice and the compressor is always running. I was told that probably the tube carrying freon is obstructed, next of that area, due to some oil pumped in it by the compressor. All this probably due to an electrical voltage spike: is it possible? Any other suggestion? thanks
It sounds as though you have a shortage of gas or a blockage. The blockage is as you describe. The refrigeration circuit continually pumps round an aount of oil which is carried in the gas. The circuit has to go through a very small tube called a capillary tub and like arteries it can become coated with oil and block. This is more common on newer systems running on R134A gas. However I would suggest that it is more probable that you have a leak. Either scenario is not a good one and would require extensive work and you would need to way that up against a new unit. If blockage then you an sometimes clear the blockage but in my experience the evaporator (internal coil) needs to be changed. If it is a leak then it could be easy or very hard to find and that impacts on the cost. I do hasten to add that only a tech would be able to see the state of the refrigeration circuit and that this is an opinion of the fault. Unfortunately the above two scenarios share the same symptoms. Hope this is of some help.
