We have a side by side Frigidair that is 7 years old. We have been having problems with it keeping things cold enough. Hubby tried cleaning the coils but now it is too warm inside to keep food ok. All frozen stuff has been moved to the freezer downstairs and the other stuff is in coolers now. Is it ever worth it to pay to have a repairman come to try and fix a refrigerator this old? Or should we just be going shopping for a new one?
