I just replaced the light bulbs on the refrigerator side. They are exactly as recommended in your manual and I took one with me to make sure what I bought was correct. They do not come on when the door opens. Is there a switch?

Yes, the Sub-Zero 600 Series refrigerator has a light switch that may cause the bulbs not to turn on when the door opens. The switch is mounted to the top mainframe in all models except 601, where it is mounted to the bottom mainframe above the unit grille. If there are two switches, the left-most one is for the light. If the switch is disconnected or defective, it can prevent the lights from turning on.

Page 16 ELECTRONIC CONTROL TERMINOLOGY & COMPONENT DESCRIPTIONS All 600 Series units utilize an electronic control system. The electronic control system monitors, regulates and con- trols 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.
Page 17: Basic Electronic Control System
Electronic Control System 600 Series (Prior to #1810000) BASIC ELECTRONIC CONTROL SYSTEM Input operations for the electronic control system are performed at the control panel, with monitoring, regulating and controlling functions taking place at the control board. Temperatures and possible problems with the unit are illumi- nated on the LCD.
Page 18: Control Board Summary / Layout
Electronic Control System 600 Series (Prior to #1810000) Control Board Summary / Layout The electrical connection points on the control board are labeled, indicating which components are connected at which connection points. Below is a layout diagram of the control board, followed by a summary table.
Page 19: Basic Input Operations
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.
Page 20: Unique Input Operations
Electronic Control System 600 Series (Prior to #1810000) UNIQUE INPUT OPERATIONS This section illustrates electronic control input operations not associated with typical unit function. Show Room Mode Showroom Mode was incorporated into the electronic control system so these appliances could be displayed in a showroom setting.
Page 21: Functions Of Electronic Control System
Electronic Control System 600 Series (Prior to #1810000) FUNCTIONS OF ELECTRONIC CONTROL SYSTEM This section covers the monitoring, regulating and controlling functions of the electronic control system. NOTE: All electronic control system functions described in this section are normal operation only. Malfunctions will be covered in later sections.
Page 22 Electronic Control System 600 Series (Prior to #1810000) 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 sig- nal is sent to the condenser fan relay on the control board to close, supplying power to the condenser fan.
Page 23: Monitor, Display, Regulate Temperatures
Electronic Control System 600 Series (Prior to #1810000) Monitor, Display and Regulate Temperatures The temperature signal from the thermistor in the refrigerator and/or freezer compartment is monitored by the micro- processor, and displayed on the LCD. Though the compartment air temperature does fluctuate, the LCD displays the average temperature.
Page 24: Monitor And Control Off-Cycle Defrost
(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.
Page 25 Electronic Control System 600 Series (Prior to #1810000) 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).
Page 26: Monitor Compressor Run, Displays If Service Or Condenser Cleaning Is Needed
Electronic Control System 600 Series (Prior to #1810000) 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).

(In this example, the refrigerator evaporator thermistor is faulty.) (See Figure 3-35) 2.
Page 31: Using Temperatures To Troubleshoot Sealed System
Using Temperatures To Troubleshoot Sealed System To give the 600 Series a true “Sealed System”, the compressor process stub is soldered shut at the factory after the sealed system is charged. Troubleshooting the sealed system is possible without a process valve because of the 600 Series Electronic Control System.
