User Manual Hisense RF540N4WF1 refrigerator

The serial number is a 23 character code made up of letters and numbers and will be written under a barcode on a small white sticker, located in one of two places:
• Inside the fridge section on the left hand side wall behind the crisper drawer
• On the back of the product (outside)
A small number of models will have a 12 character serial number starting “CNK…” on a product description label inside the fridge behind the crisper drawer.

There are a few simple checks you can do: see if the light comes on when you open the fridge door and make sure the power is connected correctly. Change the plug to another socket and be sure other electrical devices work when connected to the same power point.
