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.
