ELECTRICAL SYSTEM
Door and Drawer Switches
The door switch (fresh food door or freezer drawer) closes when the door is open. When the door
switch is closed, L1 is provided to the compartment light(s). The main control board receives L1 input
on pin 6, J7 when the fresh food door switch is closed (door open). The main control board receives L1
input on pin 7, J7 when the freezer drawer switch is closed (door open).
Master Light Switch
The Master light switch is located behind the grille panel on the control board cover. The master light
switch will open the light circuit preventing the interior lights from receiving L1; therefore, the lights will
not operate when either door is open.
Temperature Overload Device (TOD)
A temperature overload device is wired in series with both the fresh food light and the freezer light. If
either light should reach excessive temperatures due to a door/drawer being open for an extended
period, the corresponding TOD will open the light circuit. The TOD will open at 190°F and close
at 130°F.
