Help With a Discontinued Part

My 4.5 year old LG refrigerator started to click on me a week or two ago. After a few days I noticed that the freezer started to thaw out and figured that I would need to troubleshoot some. I unplugged it and started to check some things out. I am now trying to order an new start relay for my fridge but I can’t find it anywhere. It says that the part has been discontinued. Does anyone know of a comparable/universal part that I can use on my refrigerator? Any help would be much appreciated! Thank you,
