NOTE: Functional parts are common to each model configuration, meaning the models 601R/F, 601R/O and 601R/S will utilize common functional parts, just as the models 601F/F, 601F/O and 601F/S will utilize common functional parts, and so on... For this reason, the back­ward slash and letter at the end of the alpha-numeric model number will be used in this manual only when necessary.
Listed below are the twenty model numbers with a brief description of that model.
MODEL DESCRIPTIONS
This section briefly describes the models covered in this 600 Series Service Manual. Though there are twenty models, there are only seven basic model configura­tions (Models 601R, 601F, 611, 632, 642, 650, 690). The reason for twenty different model numbers is the three esthetic variations to the exterior components. The letter after the backward slash in the alpha-numeric model number indicates the exterior cosmetic variation. (“/F” indicates a Framed
look with the door trim visible, “/O” indicates that it is intended for the unit’s door pan­els to Overlay
the door trim, and “/S” indicates that the
unit is Stainless Steel.)

INSTALLATION CONSIDERATIONS
This section covers common installation issues seen by Service Technicians. Improper installation, though not a valid service issue, has the potential to lead to a call for service. Installation related complaints could include, but are not limited to: Unit leveling, unit movement, door misalignment, improper door and drawer sealing, internal frost or condensation, exterior condensation, warm compartment temperatures, etc.
NOTE: If additional installation information is needed, refer to the complete Installation Manual, or contact Sub-Zero Service Department.
Unit Leveling (All Models)
NOTE: Unit must be installed before leveling (See WARNING above). If unit is anchored to cabinets, remove anchor screws before leveling, reinstalled after.
To level a unit, first remove kickplate (See Figure 2-1). Then, to raise unit front, turn front leveler legs counter­clockwise, clockwise to lower (See Figure 2-2). At front of unit base is an adjusting screw that reaches to rear leveler/roller assembly. To raise unit rear, use 5/16” socket wrench to turn adjusting screw clockwise to raise, counterclockwise to lower (See Figure 2-2).
NOTE: Level is best checked at top & side mainframe.
Door Adjustment (All Models)
NOTE: Unit must be level before adjusting doors.
If unit is properly installed, blocked and leveled, it may still be necessary to adjust door(s) left to right and/or in and out. Adjustments are performed at top and/or bot­tom door hinge(s). Two small Phillips head shipping screws in each door hinge must be removed and dis­carded before attempting adjustments. Then, working on only one hinge at a time, loosen and re-snug door hinge mounting screws, allowing door adjustment (See Figure 2-3). After adjusting door, tighten door hinge mounting screws and check for proper door seal.
NOTE: If one door on a side-by-side unit sits higher than the other, bottom hinge spacer (part #0183100) is available. To install spacer, remove shipping screws from bottom door hinge, then loosen hinge mounting screws. Insert spacer(s) between bottom door hinge and bottom door trim. Adjust door accordingly and retighten door hinge screws. (See Figure 2-4.)
Figure 2-2. Unit Leveling
UNIT COULD TIP UNDER CERTAIN LOAD CONDI­TIONS. FAILURE TO INSTALL ANTI-TIP COMPO­NENTS AND EXTEND LEVELERS TO FLOOR ACCORDING TO INSTALLATION MANUAL COULD RESULT IN SERIOUS INJURY OR DEATH.

ELECTRONIC CONTROL TERMINOLOGY & COMPONENT DESCRIPTIONS
All 600 Series units utilize an electronic control system. The electronic control system monitors, regulates and con­trols a variety of functions, as well as displaying temperatures and possible problems with the unit. In this section, some basic electronic control system terminology is defined, and electronic control components described. An understanding of the following information is needed in order to comprehend the electronic control system.
TERM / COMPONENT DEFINITION / DESCRIPTION
Control Board The electronic board which contains the microprocessor, relays, electrical connec-
tions and LCD. The electrical hub of the electronic control system.
NOTE: See "Control Board Summary / Layout" in following section.
Microprocessor An electrical component on the control board which receives electrical signals from
other components in the electronic control system, processes that information, and then sends an electrical signal to the relays instructing them to open or close, and other electronic components to switch on or off.
Relay The electrical components on the control board which, when closed, allow power to
the appropriate components.
LCD (Liquid Crystal Display) That part of the control board seen at the control panel which displays compartment
temperatures, service indicators, etc...
Control Panel The information input and read-out area of the electronic control system. The LCD
is visible through a window on the control panel.
Membrane Switch That part of the upper control panel where all input functions are performed.
Keys Buttons on the Membrane switch used for input functions.
Indicators The words that are displayed on the LCD.
Set-Point The desired compartment temperature. This is the approximate average of the high
offset and the low offset.
High Offset The maximum compartment air temperature the electronic control system will allow.
When the high offset is reached, power is supplied to the compressor to run.
Low Offset The minimum compartment air temperature the electronic control system will allow.
When the Low Offset is reached, power to the compressor is interrupted.
Offset Temperature Range The difference between the low offset and the high offset.
Thermistor A resistor with which resistance changes as the temperature around it changes. For
electronic control system purposes, the microprocessor deciphers this resistance signal as temperature.

When in OFF mode, 115 Volts are still present at the control board.
Basic Input Operations
This section illustrates the basic input operations performed at the control panel. Switching the unit on & off, tem­perature adjustment, and switching the icemaker system on & off will be explained.
POWER ON/OFF
All 600 Series units arrive in Off Mode, and “OFF” is visible on the LCD. By pressing the UNIT ON/OFF key at this time (See Figure 3-4.), “OFF” disappears from the LCD as power is allowed past the control board to the rest of the unit, and the compartment temperatures are displayed.
NOTE: Whenever the last stroke of the UNIT ON/OFF key is off, “OFF” will be visible on the LCD.
TEMPERATURE ADJUSTMENT (ADJUSTING SET-POINT)
To adjust the compartment temperature, press the WARMER or COLDER keys on the control panel in multiple key strokes until the desired set-point is achieved. One key stroke equals a 1° F change. (See Figure 3-5.)
NOTE: Freezer temperature range is -5° F to +5° F, with an initial Set Point of 0° F; Refrigerator temperature range is 34° F to 45° F, with an initial Set Point of 38° F.
NOTE: Set-point will be displayed for 10 seconds after the last WARMER or COLDER key stroke, then the compart­ment temperature will appear. As the compartment temperature changes, the temperature displayed on the LCD will change, by no more than 1° F per minute.
Icemaker System ON/OFF
All 600 Series units arrive with the icemaker system of
f. By pressing the ICE ON/OFF key at this time, power is
allowed to the icemaker system, and “ICE” is displayed on the LCD. (See Figure 3-6.)

Control Condenser Fan Operation (Models 611, 632, 642, 650, 690)
NOTE: Power to the condenser fan on models 601R and 601F is supplied direct from the compressor.
The microprocessor senses the 115 volt output supplied to both compressors. If either compressor is running, a sig­nal is sent to the condenser fan relay on the control board to close, supplying power to the condenser fan. If both compressors are off, the condenser fan is off. (See Figure 3-10)
NOTE: The condenser fan will run 100% if the VACUUM CONDENSER indicator is activated, This will be discussed in MONITORS COMPRESSOR RUN DURATION.

Figure 3-12. Compressor Power Signal Trace
Figure 3-11. Temperature Display
Monitor, Display and Regulate Temperatures
The temperature signal from the thermistor in the refrigerator and/or freezer compartment is monitored by the micro­processor, and displayed on the LCD. Though the compartment air temperature does fluctuate, the LCD displays the average temperature. (See Figure 3-11) When the compartment temperature reaches high offset, the signal is sent to the compressor relay on the control board to close. This allows power to be supplied to the compressor and evaporator fan, which cycle on. (See Figure 3-12) As the compressor and evaporator fan run, the compartment tem­perature drops. When the compartment temperature reaches low offset, the signal is sent to the compressor relay on the control board to open. This interrupts power to the compressor and evaporator fan, cycling them off.
NOTE: If the compartment temperature should ever exceed either the high offset or low offset (for example: when a door is left open), the temperature displayed on the LCD will change by one degree per minute.

Figure 3-13. Refrigerator Compressor OFF
Figure 3-14. Defrost Heater Signal Trace
Monitor and Control Rerigerator Off-cycle Defrost
Temperature signals from the refrigerator compartment thermistor and evaporator thermistor are monitored by the microprocessor. If the compartment temperature reaches high offset before the evaporator rises to 38°F, the command to start the compressor will wait, allowing the evaporator to fully defrost before the compressor is energized. (See Figure 3-13)
Monitor and Control Freezer “Adaptive Defrost”
Initially the freezer compressor in a 600 Series unit will cycle-run for 12 hours, after which the microprocessor sends the signal to the defrost relay on the control board to close. This supplies power to the defrost heater, and the compressor is switched off. (See Figure 3-14) With the “Adaptive Defrost” technique, the length of time that the heater actually stays on to defrost the evaporator and satisfy the defrost terminator is observed by the microprocessor. The microproces­sor then determines the number of hours before the next defrost. If the heater stays on for a shorter time than specified, the microprocessor increases the next defrost interval. If the heater stays on longer than spec­ified, the electronic control decreases the next defrost interval. This is an ongoing process whereby the defrost time and the defrost interval will vary by unit use.
NOTE: A five (5) minute delay/dwell follows all defrosts.
NOTE: Minimum defrost interval = six (6) hours;
Maximum defrost duration = twenty-five (25) minutes.
Initiating Freezer Manual Defrost
To manually initiate freezer evaporator defrost, press and hold the ICE key at the control panel for ten sec­onds. (See Figure 3-15).
NOTE: To observe the initiation of manual defrost, “ICE” must be displayed on the LCD. Then press and hold the ICE key for ten seconds. At first, “ICE” will dis­appear. After ten seconds of holding the ICE key, “ICE” will appear again, indicating manual defrost has begun.

Monitor Icemaker System and Display If Service Is Needed.
The microprocessor monitors the voltage supplied to the icemaker water valve (See Figure 3-16). If the water valve is energized for more than fifteen (15) seconds, power to the icemaker system is interupted, and a signal is sent to the SERVICE and ICE indicators on the LCD to flash (See Figure 3-17).
NOTE: To allow ice to freeze fully and reduce effects of low water pressure, the electronic control system disables the icemaker system for 45 minutes after each ice harvest.

Monitor Compressor Run Duration, Displays If Service, or Condenser Cleaning Is Needed
The microprocessor senses the 115 volt output supplied to both compressors, monitoring the length of compressor run time (See Figure 3-18).
If several excessive compressor run periods occur, the microprocessor closes the condenser fan relay on the control board, allowing the condenser fan to run 100%. A signal is then sent to the VACUUM CONDENSER indicator on the LCD to flash (See Figure 3-19).
NOTE: Please keep in mind that a flashing VACUUM CONDENSER indicator is caused by excessive compressor run, which could be related to problems other than a dirty condenser. This will be covered in the TROUBLESHOOTING GUIDE.
NOTE: After correcting the cause of the error, the unit must be switched OFF, and back ON to clear the error indica­tor.
