>> View Section 3 of the Video Tape SECTION 3 THEORY OF OPERATION TEMPERATURE CONTROLLED MEAT LOCKER The 26" deep side-by-side refrigerator/freezer is equipped with a chilled meat locker which will keep the contents of the drawer approximately 5°F colder than the rest of the refrigerator section. (Fig. 5) A slide on the front of the drawer operates a damper which directly controls the amount of freezer air drawn into the drawer through an air duct. AIR DUCT ▲ ▲ DAMPER ▲ Fig.

6. Dispense ice by holding glass against ice lever arm. The mechanically operated ice chute door opens, and the motor driven helix is energized and ice is automatically dispensed into glass. When glass is withdrawn, a delay mechanism slowly closes the ice chute door. ! ▲ WARNING To avoid risk of personal Injury or property damage, refrigerator must be unplugged and ice storage bin must be removed before attempting to service dispenser system.
6. If odor, taste and sediment are a problem, a granulated activated carbon filter should be installed on the household plumbing line. 7. Underneath the ice and water dispenser is a small sump to catch any spillage that may occur. This is not a drain. However the sump is heated to speed up water evaporation. A removable grille is provided as a sump cover. 8. A six watt lamp is activated each time the water or ice dispensing lever arms are depressed.
TEMPERATURE CONTROL OPERATION 1. Freezer temperature is regulated by an air sensing thermostat located at the top rear of the refrigerator compartment. A sensing tube goes into a well which routes the tube into the freezer section. This thermostat actuates the compressor to circulate refrigerant through the sealed system. (Fig. 10) The thermostat should be set to maintain 0°F to 2°F freezer food temperature. REFRIGERANT FLOW Freezer Temperature Sensor Fig.
2. Refrigerator temperature is regulated by an air damper control. This control governs the amount of refrigerated air entering the refrigerator compartment. (Fig. 11) The control should be set to maintain 28°F to 40°F fresh food temperature. Air Supply to Refrigerator Compartment Freezer Back (Air Baffle) Cold Air Damper Meat locker Air Evaporator Fan Air Return Condenser Fan Evaporator Compressor Condenser AIR FLOW Fig.
ADAPTIVE DEFROST OPERATION 1. This unit is equipped with Adaptive Defrost Control (ADC). (Fig. 12) A defrost cycle occurs after a predetermined length of compressor run time. The length of accumulated compressor run time is determined by a microprocessor that monitors the length of a defrost cycle (the time) interval between energizing the defrost heater and the defrost thermostat opening). The microprocessor then adapts or changes the amount of accumulated compressor run time between defrost cycles. Fig.
4. Vacation Mode Defrost Interval Interruption: The Vacation Mode Defrost Interval will be interrupted when either the freezer or refrigerator door is opened. • The next defrost cycle will occur 8 hours after the door is opened and the ADC will revert to CRTD (1) = 8 hours. • If the defrost thermostat remains closed for 19 minutes or more, the ADC will revert the CRTD back one level. 5.
>> View Section 4 of the Video Tape SECTION 4 COMPONENT ACCESS Accessing the components in the 26" Deep Side-by-Side Refrigerator/Freezer is generally quite similar to other typical Whirlpool units. COMPONENT COMPARTMENT Components located in the component compartment are assembled on a slide out tray at the bottom of the unit. The compressor, condenser, condenser fan and water valves are located in this area.
Accessing the Heat Exchanger and Wiring Harness The heat exchanger, water supply tube to the automatic ice maker and wiring harness are located under two (2) metal heat exchanger covers on the back of the cabinet. 1. Remove the seven (7) hex-head screws securing the component compartment cover to the cabinet. 2. Remove the eight (8) hex-head screws securing the long metal cover to the back of the cabinet. 3. Remove the six (6) hex-head screws securing the L-shaped cover to the back of the cabinet.
NOTE: When replacing the motor box be sure the wiring harness routes through the box correctly. Portions of the harness are covered with a plastic sheath that allows the wiring to pass into and out of the box at the top (down from the automatic ice maker) and right side (to the light fixture.) Replacement: 1. Reconnect the wiring harness connectors to the motor and start capacitor. 2. Align the four (4) locator tabs at the back of the motor box with the four slots in the rear cover of the freezer section.
Removing the Evaporator Fan Motor EVAPORATOR FAN SHROUD The evaporator fan motor is mounted on a bracket that is attached to a shroud mounted to the back wall of the freezer section. (Fig. 18) 1. Removing the two (2) hex-head screws that secure the fan motor bracket to the shroud. Fig. 18 FAN MOTOR BRACKET 2. Disconnect the wiring harness connectors from the evaporator fan motor terminals. Servicing the Evaporator, Defrost Bi-Metal and Defrost Heater The evaporator, defrost bi-metal (Fig.
Refrigerator Section The thermostat, air ducts and drinking water reservoir are all accessible from inside the refrigerator section. Removing the Drinking Water Reservoir The drinking water reservoir (Fig. 21) is located at the bottom of the refrigerator section. NOTE: The bottom shelf and vegetable crispers must be removed. 1. Depress the top tabs on the drinking water reservoir cover. RESERVOIR COVER 2. Pull the top of the cover forward and dislodge the bottom tabs. 3.
COLD AIR DUCT Removing Cold Air Damper 1. Remove the control cover. 2. Remove the two (2) phillips-head screws securing the cold air damper to the duct work. (Fig. 24) 3. Remove the cold air damper from the unit. Fig. 24 DAMPER ASSEMBLY ICE AND WATER DISPENSING UNIT The freezer door contains the drinking water and cubed and crushed ice dispensing unit. A description of the cubed and crushed ice delivery process can be found in Section Two, "Theory of Operation", in this Job Aid.
Fig. 29 Fig. 28 FLUSH LOOK MODELS Factory Installed Flush Look Trim Package A FLUSH LOOK (BUILT-IN) model can be purchased with factory installed perimeter molding around the doors. This molding extends beyond the top of the door to hide the top hinges and is designed to accommodate custom panels for both the refrigerator and freezer doors. These models have a modified top hinge to allow the door to open fully with the perimeter molding in place. CUT OUT FOR DOOR TRIM HINGE COVER Fig.
