Troubleshooting the Muthaboard in GE Profile Arctica Side-by-Side Refrigerators with the CustomCool™ Feature

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:
