I am a little confused by this, are all three one wire sensors soldered to the same wire heading out of the fridge?
Yes, the white cable has 3 strands: 5V, Data, GND. It connects to 3x 5V, 3x Data, 3x GND. The OneWire sensors are identified by address and are all connected in parallel on the same bus.
