Fridge - Power Goes off and on

Hi. Make sure your incoming power and connection at the outlet is good and not causing your power to cut in and out. Unplug for 15 mins to reset and see if that fixes the issue. If still having an issue you could have a short in the wiring or a loose connection somewhere. IF not you main control board is most likely faulty. p# 5303918558. attached is a link to the part. Where is the water line freezing at? In the door or in the refrigerator section?Are temperatures in the refrigerator too cold causing the water reservoir to freeze? Attached is the tech sheet on this unit as well.
