Product review (5 stars): If substituting #242000406 with #5303918498, you must also buy this board
Please note that if you are substituting refrigerator Electronic Control Board Part #242000406 with #5303918498, you must also replace Electrolux #241973702 with this part #241973711 Electrical Control (the one above the ice/water dispenser). Part #5303918498 will not work if you do not replace the additional board. After replacing both boards, the refrigerator started up perfectly fine.
