THEORY OF OPERATION

TEMPERATURE MANAGEMENT

The KitchenAid French Door Bottom-Mount

Refrigerator uses a thermistor in each cooling compartment to maintain proper temperatures. An electronic control, mounted in the unit compartment, monitors the thermistors in each compartment. As the freezer temperature warms, the control energizes the compressor and evaporator fan motors to cool the compartment.

When the refrigerator temperature rises and warms the refrigerator thermistor, the control energizes the mechanical air damper motor to move it to the open position. At the same time, the evaporator fan motor begins to run to bring cool air up from the freezer. As noted above, the compressor will run as needed based on the temperature in the freezer compartment, but the evaporator fan motor can run without the compressor when the refrigerator is calling for cooling.

REFRIGERATOR

DAMPER OPERATION

When the refrigerator compartment warms and cooling is required, power is applied to the

YL/RD wire on the damper switch. The damper motor runs until the damper switch changes to the normally open (N.O.) position, and the motor stops with the damper door fully open.

Power remains on the YL/RD wire as long as cooling is required.

When the proper temperature is reached in the refrigerator compartment, the electronic control switches power to the BU/RD wire. The motor runs until the damper switch closes into the normally closed (N.C.) position, and the motor stops with the damper door fully closed.

Power will always be applied to either the BU/RD

(temperature satisfied and the damper door is closed), or the YL/RD (calling for cooling and the damper door is open). The maximum opening or closing time is 36 seconds.

ICE PRODUCTION RATE

Normal Ice Production:

The ice maker should produce a complete batch of ice every

3 hours. If ice is not being made fast enough, adjust the freezer control to a lower (colder) number in steps. Wait 24 hours. If necessary, gradually adjust the freezer control to the lowest setting. Wait 24 hours between each adjustment.

OptimIce Production (Some Models):

The ice maker should produce approximately 16 to 20 batches of ice in a 24-hour period. If your refrigerator has the OptimIce production feature, press the OptimIce touchpad.

•

•

•

REMEMBER

Allow 24 hours to produce the first batch of ice. Discard the first three batches of ice produced.

The quality of your ice will be only as good as the quality of the water supplied to your ice maker. Avoid connecting the ice maker to a softened water supply. Water softener chemicals (such as salt) can damage parts of the ice maker and lead to poor quality ice. If a softened water supply cannot be avoided, make sure the water softener is operating properly and is well maintained.

Do not store anything on top of the ice maker, or in the ice storage bin.

COMPONENT TESTING

•

•

Before testing any of the components, perform the following checks:

The most common cause for control failure is corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures.

All tests/checks should be made with a

VOM or DVM having a sensitivity of 20,000 ohms-per-volt DC, or greater.

•

• Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.

Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.
