I have a Samsung refrigerator (double door up top and freezer door on bottom). The unit has worked great since purchasing 11 years ago. We recently moved to another house close by. The house was professionally cleaned which included cleaning the inside of the refrigerator and freezer. The cleaning occurred on a Sunday, when i returned the following weekend both the fridge and freezer where not cooling at all. The lights, ice, and water display were working fine. Is it possible that something was switched off while cleaning or is it just a coincidence that it stopped working after it was cleaned. Any suggestions on what it could be? I unplugged the unit.
