초록 ▼

An apparatus for driving a fan as part of a refrigerator is disclosed. The refrigerator has a compartment, a compressor, an evaporator and a condenser. A temperature sensor is positioned in association with the compartment and outputs a sensed temperature signal as a function of the temperature in the compartment. The apparatus includes a reference circuit which provides a desired temperature signal representative of a desired temperature. A comparator compares the desired temperature signal and the sensed temperature signal and generates a cool signal when the compartment temperature is above the desired temperature. A timer times out an elapsed period of time commencing when the cool signal is generated. A motor includes a rotatable assembly in driving relation to the fan. A control circuit controls operation of the motor as a function of the sensed temperature signal and the elapsed period. Related apparatus and methods are also disclosed.
