Evaporator Temperature Sensor / Switch: Description and Operation
Ranco Thermostat
Ranco Thermostat
Is an electrical switch which passes current at all times except when its sensing probe, attached to the evaporator, drops to 2°C (36°F). When this occurs,
the Ranco Thermostat becomes non-conductive and the circuit to the compressor clutch is disengaged closing down the refrigeration system to prevent
evaporator freeze-up.
