Installation and Start-Up
To access the circuit board, pull outward on the two
small, black plastic pins at the top and bottom of the
alarm/monitor control panel. (Refer to Figure 2-3.) A
noticeable “click” signals that they have released. The
battery pack is attached by hook and loop material
directly behind the liquid crystal display.
Plug the wires into the battery connector on the
circuit board, shown as item A in Figure 2-4.
If the battery pack is not plugged in, the liquid crystal display will show all
black when the refrigerator is turned on.
The circuit board is replaced by inserting the plastic pins completely into
their holes and pushing the top of the fastener inward until it “clicks.”
The battery pack is recyclable and should be disposed of accordingly.
