Wiring a fridge thermostat typically involves connecting the thermostat to the power source and the compressor. Here's a general guide for wiring a 3-pin thermostat:

1. Identify the Pins: The thermostat will typically have three pins labeled 4, 6, and 3.
2. Connect the Power Source: Pin 4 is usually the common (C) terminal, which connects to the power source. This could be the live wire from your electrical supply.
3. Connect the Compressor: Pin 6 is often the normally open (NO) terminal, which connects to the compressor. This allows power to flow to the compressor when the temperature rises above the set threshold.
