How to replace a freezer electronic control board
This DIY repair guide explains how to replace an electronic control board in a freezer. The electronic control board starts and stops the compressor and fans to maintain the freezer temperature.
Because other parts can also affect the operation of the fans and compressor, have a local freezer repair expert test the board to confirm it's the problem. Replace the electronic control board with the manufacturer-approved freestanding freezer part.
This repair guide and video shows how to replace the electronic control board in Kenmore, Frigidaire, Crosley, Gibson, and Kelvinator upright freezers.
