@kysee bi-metallic principles are used in thermostats and a fridge is one of the appliances with a thermostat.
Quote " Thermostats are usually located inside the
refrigerator and have a knob or control panel
that allows users to adjust them. Most older
appliances have just one thermostat for the
entire device, but some newer models allow
for different settings in different areas: users
might choose to keep the main chamber
cooler than one or more drawers, for
instance. Once a user sets the desired
temperature, the thermostat maintains that
temperature by sensing internal fluctuations
and prompting the compressor to turn on or
off in response to those changes. When the
refrigerator is appropriately adjusted to the
designated temperature, the THERMOSTAT STOPS THE FLOW OF ELECTRICITY to the compressor,
effectively stopping it from cooling the
appliance."
