Question about Refrigerators
Last 3 months unit does not get cold enough...refrigerator about 48 degrees and freezer 30 degrees. On coldest setting. have cleaned the coils in back..good seal..compessor runs...fan inside runs. 7 year old unit..very good condition...would a bad defrost heater cause this...or that little sensor. Frigidaire model FRT21G3A
First, on some versions of your machine, there is a fan on the bottom rear, make sure if it has one, that it is running.
If it were a defrost component, as you suggested, then you would see a build up of frost and ice on the rear panel in the freezer compartment.
If so, you would need to defrost it. There are 3 components to a defrost system. The 2 you described, behind that rear panel, and a timer in the fresh food compartment, in the upper housing.
Below is a tutorial on defrost systems. You need a ohm meter to test the components.
If none of the above apply, then it is in the sealed system (compressor, leaks in the tubing or restriction in the lines) and would require a trained tech to sort it out.
