I would hope a brand new fridge would last at least a few years without needing service.
But this one didn't last six months. 
The warranty service wasn't available in my area (Central Vermont), so keep that piece of info in mind if you don't live near a metro area. 
We replaced it with a fridge literally from 1950. 
The effort to manually defrost the old fridge is worth it if it means it will function for 70 years. 
Why does a new appliance fail within a year!?
Is "Planned Obsolescence" ramping up!?
