    摘要: A low cost method and apparatus for indicating when to replace a water filter in a water and ice delivery system for a refrigerator. The invention uses a low cost microprocessor and senses the operational condition of an ice maker water valve, a water dispenser valve to monitor and track water usage. The microprocessor has a built-in memory to retain water usage and other data during a power outage. The invention also senses the status of a door switch to permit user input of a reset message indicating that the filter has been changed as well as an input indicating a different type of filter has been installed. The microprocessor controls a tri-color light emitting diode to display the status of the filter as “good”, “order” or “change” which is determined based on the selection of the type of filter system, the amount of time since the last filter change, and the amount of water usage since the last filter change.

    摘要: An automatic ice maker control circuit having an improved tolerance to sense the presence of stuck ice pieces in a predetermined pocket of an ice tray. A solid state temperature sensor and time delay circuit includes an operational amplifier controlled by a temperature sensor in one portion of a bridge network for sensing above or below freezing temperatures in the pocket, depending upon the presence of liquid or a stuck cube respectively, in said sensing pocket. The ice maker is conditioned for immediate harvest after the below freezing temperature is effected in the tray pocket when the sensor senses an above-freezing temperature. The time delay circuit conditions the ice maker for a delayed harvest until the predetermined temperature is effected in the tray sensing pocket if the sensor senses a below-freezing temperature.
