Hi @kayjordan
Are the lights working in the refrigerator?
''If they're not'' working, then if you've proven that there's power available at the wall outlet where the refrigerator is connected, check if the 250V 10A glass fuse on the EMI filter board in the refrigerator is OK and not blown.
Below is an image showing the fuse on the board. It would be cheaper to replace the fuse than to replace the whole board but you would have to solder it in. If you wish to change the board, search online for [https://www.google.com/search?client=firefox-b-d&q=Samsung+DA27-00022B|Samsung DA27-00022B] to find suppliers that suit you best.
''If the lights are working,'' then it may be a problem on the control board.
