Customer Questions and Answers for Board-Switch by Frigidaire

Dennis, You are correct, The main control board / switch board 5303918498 is the defrost system control(among other things as well). It is located on the bottom of the refrigerator compartment in the box,located behing the kickplate grille. You'll need to remove the two screws that hold the retainer clip in place, so you will need a combination wrench / socket to remove the 1/4 in. hex head screws or raise the front of the fridge. Once the clip is removed, you'll need to slide the box out the front, enough to disconnect the harness, then slide the box out the rest of the way and reverse the procedure to install the new part. Thanks
