Six years old???? What a travesty! My fridge, washer, and dryer are over 20 years old. My washer is just starting to kick the bucket. Sure glad we are going "green" in this country and filling our landfills with inferior products.
The new appliances are not nearly as well made as even a 20 year old appliance.
I have a 50 year old refrigerator that is still running fine.
It is only used for large events when the kitchen refrigerator is filled.
The efficiency is probably the pits.
it did need a new door gasket a few years ago.
It is rarely worth major work on the compressor.
There are no valves or fittings on a refrigerator, so adding schrader valves is part of the cost of working on the refrigeration loop.
A good technician will be able to recover the refrigerant (simply venting it is not allowed).
