When your old capillary thermostat goes bad inside your refrigerator, you can either replace it with another analog thermostat or with a digital one from ebay for instance: the Meihang Technology MH1230A temperature controller.

Step 1: Remove Old Thermostat

Unscrew the thermostat block on the inside of the refrigerator.

On the bottom you will find a lid with 2-3 latches on one side that can be opened by hand, and one on the other that can be pried open with a small screwdriver.

Step 2: Connect the Temperature Controller

Brown and blue used to power the light bulb after opening the fridge door.

White and brown seemed to be the same, so I put them together.
