The service data sheet that came with the 10-year-old Hotpoint (GE) 18-cubic-foot top-mount no-frost in my house says that with the freezer knob at 5 (on a scale of 1 to 9) and the fresh-food knob (if equipped) at C, which is also the middle, you should have:70 F ambient: Fresh food 33-39 F, freezer -4 to +2 F, percent run time 26 to 36%90 F ambient: Fresh food 33-41 F, freezer -4 to +4 F, percent run time 40 to 56%The service data sheet that came with my 3-year-old Frigidaire (Electrolux) 18-cubic-foot top-mount no-frost at my rental says that with no load, the doors closed, and the controls set in the middle, you should have:65 F ambient: Fresh food 35-40 F, freezer +2 to +8 F, percent run time 25% to 35%90 F ambient: Fresh food 35-40 F, freezer 0 to +5 F, percent run time 45 to 55%Another rule of thumb I have heard is that if you have a box/tub of ice cream in the freezer, it should be soft enough that you can scoop it - not a solid block but not runny either.Like @Jennifer Rysdam and @Joe Splitrock said, cleaning the coils can help. 

And then some other things to protect it long term and alleviate some capex things (gutters, basic updates to electrical, a few plumbing repairs, a little motor work in the garage and basement, a new concrete front stoop).

It needs to be cleaned and have a blower motor replaced for an estimated $250.

Might need a new capacitor or motor.

Frank Ross downtown Mount Pleasant has experience working with real estate investors and has owned a rental property himself I just started using him this last year but he has been super helpful and is okay with calling occasionally with questions without a cost (probably because I did my taxes there).  

@Brandon Sturgill thank you I live in Mount Vernon oh definitely interested in wholesaling
