Test Continuity: Use a multimeter to check for electrical continuity in the thermostat circuit
To test the continuity of the thermostat circuit in your refrigerator, you'll need a multimeter, which is a versatile tool for measuring electrical properties. First, ensure the refrigerator is unplugged to avoid any electrical hazards. Then, locate the thermostat, which is typically found inside the refrigerator compartment, often near the temperature control panel.
