Fridge in hot garage not getting cold in summer

I have an 11 year old Whirlpool top mount fridge that I keep in the garage. During the winter it works great. However, as spring and summer come and the garage starts to get warm (into the 80s and 90s), the fridge only cools down to about 60 degrees. During these hot times the freezer is usually fluctuating between -10 and +10 degrees. If this is not a repairable is there a good fridge that someone can recommend for my situation?

Thank you for any help you can provide!

An uninsulated garage is an environment that was never intended for a rerigerator to be. The job of the refrigerator is to transfer the heat from the food inside to the atmosphere outside. This requires that the outside temperature be at least cooler than the temperature of the refrigerant as it condenses. A refrigerator cannot transfer heat into a hotter environment.

I believe there are models that are designed with a little more stamina for this hostile environment; They are advertised as “garage refrigerators”. But for the most part, the heat of your garage in summer will always be a problem.
