You must order both the Control-Electrical (part that goes behind the display) and control main power board (part under the left front side under freezer) or it doesn’t work. I only ordered the main power board and it didn’t fix the problem. Once I got the door display part it’s working good as new. It only took me 20 minutes to install both parts! Only bad news is I don’t have an excuse to buy a new fridge! Haha
