Question about Frigidaire FRT15B3A Top Freezer Refrigerator
If the machine runs then it is not the cold control. You need to remove the rear panel in the freezer compartment and on that model usually means removing the vertical chute running up the center of the back panel and as well removing the fan motor.
I assume the fan motor is running. if not, that is your problem.
Before doing any of this make sure the light goes out when you close the door. You can see it go off just before the door closes.
That would produce enough heat to cause the fresh food section to run warm.Check that chute you removed to see if ice built up in it, as well as the the hole it discharges air into the fridge section.
Once you remove the rear panel, inspect the coil for ice build up.
If the coil is iced it will need to be defrosted.
If the coil is badly iced or frosted up, then you have an auto defrost problem. The defrost system is made up of 3 parts. The timer, which is located behind the cold control, and then back in the freezer compartment the main heater which runs along the bottom of the cooling coil or the defrost thermostat that is a small 1" disk which is clipped to the top of the coil on the right side although somwhat hidden behind some styrofoam.
In most cases it is either the timer or the defrost thermostat that has failed.
A good tutorial follows at the end of this post.
If all of the above proves to be O.K. then on Frigidaires, they have a tendency to ice up the return ducts. You can't see them, and you can't defrost them. The only way is to unplug the machine for 24 hours and let it melt out on it's own.

It may not be your cold colntrol. it is more likely the defrost terminator or the heating element (both located in the freezer section) or the defrost timer (located in the refrigerator section). you most likely have an ice buil-up on the evaporator coil that is preventing proper circulation of air accross the coil and into the refrigerator section.
