Over-temperature warning system for refrigerator appliance |
摘要 |
An improved over-temperature warning system for a refrigerator/freezer appliance comprises a temperature sensor responsive to the temperature in the freezer compartment of the appliance and logic circuitry responsive to the sensor operative to detect a first over-temperature condition when the sensed temperature is greater than a first reference temperature and less than a second reference temperature and to detect a second over-temperature condition when the sensed temperature is greater than the second reference temperature. The logic circuitry times the duration of the first and second over-temperature conditions and provides a user discernible warning signal when the first condition exceeds a first predetermined time period or when the second over-temperature condition exceeds a second predetermined time period shorter than the first time period.
