The CustomCool is a gimmicky marketing name that GE came up with for what is basically a souped-up crisper drawer in the refrigerator. The drawer has been outfitted with a system of dampers, a fan, a temperature thermistor and a heater. Depending on the function selected on the CustomCool settings in the controls at the top of the refrigerator, a combination of these components can be used to theoretically chill items quickly, thaw items or hold the drawer pan at a specific temperature.
CustomCool™ should not be confused with TurboCool™, which is yet another gimmicky marketing name for a different feature of dubious value in the some GE refrigerators.
I’ve previously posted troubleshooting flowcharts for GE refrigerators and a generic warm refrigerator troubleshooting flowchart. This flowchart is a little different– it’s for troubleshooting the muthaboard in GE Profile Arctica refrigerators with the CustomCool™ feature. You can download it here:

As a result of your troubleshooting using the flowchart that I’ve graciously and generously provided above, you’ll probably find one of the components in this handy list needs to be replaced. I’ve included links to more information on each item. And you can conveniently buy them right here– just click the pictures to get ’em. Your purchase is what helps keep this site going so if you like what I do here, please buy your appliance parts through my links. Domo!
