For more information and/or to illustrate, you can right click on some photos/images to enlarge them for a better view. Move your mouse over a word or photo and it will change if it is a link (highlight, change color, a hand may appear).
The hardest part of this repair is removing the plastic cover in the ceiling of the refrigerator compartment to get to the ADC. It goes back in pretty easily, especially when you know how it looks/works on the other side.
You now know what the ADC looks like and where to find it. On this page, you are given
a look inside the control panel - the actual parts.
Replacing the ADC
As you know, there are many different brands, models and the age factor that makes it almost impossible to provide materials to cover every refrigerator. You will find some generic information that may or may not apply to your specific refrigerator. Look for a repair manual for your specific refrigerator if you need more information/guidance and to check if your refrigerator does or doesn't have certain parts/features.
Most ADC replacement kits come with instructions.

Refrigerator Compartment Control Diagram
Refrigerator Control Diagram for use while you are replacing the adaptive defrost control (ADC).
The replacement part is a little different from the original in that it is now encased in a plastic housing, whereas the original was just a bare board. The plastic container supposedly helps "protect" the board from "frost" (moisture). Also, the new ones have an LED light to help diagnose trouble.....BUT,...The control cover needs to be open to observe the light!
This is a basic layout of some
refrigerator control parts. Your model may be different.

There are many different brands, models and the age factor that makes it almost impossible to provide materials to cover every refrigerator. You will find some generic information that may or may not apply to your specific refrigerator. Look for a repair manual for your specific refrigerator, e.g., Kenmore, Whirlpool,
older GE/Hotpoint, if you need more information/guidance and to check if your refrigerator does or doesn't have certain parts/features.
Some refrigerators have
mechanical defrost timers, while others are controlled by
motherboards (GE motherboard). You may see some similarity among models since some brands are made by the same manufacturer with different names. The ADC Finder/Prices button on this page may help you find your ADC if your refrigerator has one.
