How to replace the electronic control board inside a top-freezer refrigerator
This DIY repair guide gives instructions for replacing the electronic control board inside a top-freezer refrigerator. The control board is located inside the control box at the top of the refrigerator section.
When the electronic control board senses the temperature in the refrigerator rising, it sends voltage to the compressor and fans to begin the cooling cycle. The control board also controls the defrost cycle, based on temperatures inside the refrigerator and freezer sections. If the electronic control board fails, the compressor won't run and the freezer won't defrost. Because problems with parts other than the electronic control board can cause the same symptoms, a local refrigerator repair expert should test the electronic control board. If the control board isn't working, replace it with the manufacturer-approved refrigerator part that fits your refrigerator model.
This repair procedure shows how to replace the electronic control board in some Kenmore and Frigidaire top-freezer refrigerators. You can use the same basic procedure to replace the electronic control board in some Whirlpool, KitchenAid, Maytag, Amana, GE and Haier refrigerators.
Use our repair guide/video How to replace the electronic control board on the back of a refrigerator if that’s where the control board is on your top-freezer, bottom-freezer or side-by-side refrigerator.
