Freezer are not made away near as good as they use to be, picked up a chest freezer 2nd hand that was 10 years old and kept in my basement, I bought a new one just in case the old one crapped out. After 5 years the new one stopped working for no reason, took old one to Florida with me 3 years ago, it still freezes to -10 degrees. After 18 year it is still works great. Who even said new is better hasn't been around long enough to prove it.
Bad news for you. That’s the law of averages.
Yes, some parts of fridges and freezers are not as well made. But that reduction in quality predates that freezer of yours. It went down in the 80s and 90s. Not recently.
And the scroll motors in compressors these days are typically better than those of older compressors. QA on the lines however is much lower than decades ago.
But it is still a bell curve. Hit a year or two and odds are excellent it’ll last decades.
So far in my life I’ve had 8 fridge-freezers and a chest freezer, including mini fridges, not including appliances in rentals or dorms, with a total of probably 50 appliance years between them all.
I’ve had one die and the compressor was replaced days within the 1 year warranty and it was still going strong when I just sold my rental a few months ago with I think 12 or 13 years in the replacement compressor.
None of the rest have died.
I have a friend who has had 3 or 4 die on him over a decade.
Typically with no manufacturing defect and not abused (IE kept in a really warm place), the type of compressor used for refrigeration in a residential fridge or freezer is a 15-25 year expected life. Old or new. Does better than that, great. Worse, than that sucks. Just taking an average.
