Frigidaire model ftr18b freezer works, fridge is only cool

Info relating specifically to the Frigidaire FRT18B5ABB:

1.Refrigerator unplugged remove the bottom back panel. (Access cover with label. The rectangular shaped panel on the back, at the bottom) Place the screws in a container.
Also remove the Kickplate Grille in the front, and the defrost pan.

2.Use the wand tip on your vacuum cleaner, and vacuum this area out. Pay special attention to the condenser coils, and the fan. Use care as you don't want to bend the fan blades. After you have vacuumed up as much as possible, see if your vacuum has where you can attach the hose to blow air through it. An air compressor, hose, and air nozzle would be REAL handy right now! Blow the condenser coils, and all areas clean of any gunk. (Hair, spider webs, etc.) If this is not feasible for you, you'll need some sort of long, thin, dust 'bunny', and have to dislodge this 'gunk' physically. Then vacuum.

3.BE SURE to replace the bottom back panel, (Access Cover)! It is a VERY necessary item! If your fridge doesn't have one at present, make a temporary one of cardboard, and tape it on. This access cover is needed.

If your refrigerator side is only cool, and your freezer is cold, you may have a problem with the Cold Control, (Temperature Control), or the Defrost Timer. (Timer-Defrost)
