My fridge wasnt cooling, the issue was fixed by defrosting my freezer. 10 days later the same buildup is happening and the technician is saying its now parts. I paid over 300$ for them to defrost my freezer essentially and theyre saying I need a thermostat when my fridge is cooling, my freezer is still building up ice . I believe its something around the fridge that needs to be sealed. Awful customer service would not recommend
