Motorized Air Operation
A motorized air door regulates the air flow coming from the freezer. The operation of the motorized air
door is determined by the following components:
•
The temperature sensor (thermistor) located on the back wall of the refrigerator cover.
•
The electronic control board located inside the refrigerator section control cover.
When the temperature sensor calls for cooling in the refrigerator section, the electronic control energizes
the air door motor and opens the baffle (Fig 6-A). from the "closed" position, the baffle rotates clockwise
270°. During this rotation it opens, closes and then parks in the "open" position. The OPEN MICRO-
SWITCH shuts the door motor off when the baffle is fully open.
When the temperature sensor is satisfied, the electronic control again energizes the air door motor and
closes the baffle (Fig 6-B). from the "open" position, the door rotates clockwise 90° and parks in the
"closed" position. The CLOSED MICRO SWITCH shuts off the door motor when the baffle is fully
closed.
Air Circulation in the Meat Savor Drawer
The Meat Savor drawer in the refrigerator compartment is provided with a separate controlled flow of
cold air from the freezer compartment. Air enters the Meat Savor drawer through an air passage through
the center divider wall into the upper part of the Meat Savor drawer control. If the control knob is rotated
fully counterclockwise the control knob arrow is pointing to "COLD" (Fig 7A). In this position the cold
air is blocked by the baffle and will not enter the Meat Savor drawer.
As the control knob is turned clockwise (toward the "COLDEST" setting), cold air will be able to pass
around the baffle into the lower part of the Meat Savor control it can flow through the round port into the
Meat Savor drawer. Air then leaves the drawer and joins the normal air circulation in the refrigerator
compartment and return to the freezer compartment through the return air ducts in the center divider wall.
