Abstract: A control indicator optic arrangement and indicating method for a refrigerator having an access door, an interior light bulb that is illuminated when the door is open, and antisweat heaters that are energized by an on-off switch. Included is a movable switch member that energizes the antisweat heaters and a shade member slidable in unison with the switch member and having a cutout area. A light transmitting rod from the interior light bulb to the shade member is arranged such that when the switch is in a first position to energize the antisweat heaters the transmitting rod is in alignment with the cutout area of the shade member and in the second position when the antisweat heaters are de-energized it is out of alignment with the cutout area. Thus, with this arrangement there is a visual indicator to alert the refrigerator user to the fact that the antisweat heaters are energized.

Abstract: The defrost pressure control system for a refrigerator includes a reservoir connected in communication with the evaporator of the refrigerating system. The reservoir is placed in heat exchange relationship with a portion of the refrigerator which remains at a relatively low temperature during defrosting so that a portion of the refrigerant in the system condenses in the reservoir during defrosting, thereby being effectively removed from the refrigerating system. A suitable heat sink may also be employed in the heat exchange relationship with the reservoir. Because of withdrawal of the aforementioned refrigerant, the pressure in the refrigerating system at the end of the defrosting operation is substantially below that which would otherwise be present. As a result the torque required to start the compressor is significantly reduced, thereby insuring effective starting of the compressor even when driven by an electric motor having a relatively low starting torque.
