Manual Component Activation Mode - Sub-Zero 700-3 BASE Technical & Service Manual

Integrated
If Error Codes are observed in Diagnostic Mode, a non-flashing SERVICE icon will appear on the LCD when
Diagnostic Mode ends, indicating error codes are still stored (See Figure 3-39). To clear a non-flashing SERVICE
icon and the error codes, the problem must be corrected and the unit must be ON, then the door ajar alarm bell
ON/OFF key must be pressed and held for 15 seconds. The control will emit a short "beep" when the SERVICE
icon and error codes are cleared. (See Figure 3-40)

Manual Component Activation Mode

Manual Component Activation Mode energizes the cooling system for 5 minutes, allowing a Service Technician to
check for proper voltage readings at activated components without having to wait for the zone to call for cooling.
To initiate Manual Component Activation Mode the unit must be ON, then press and hold the desired COLDER key
and the UNIT ON/OFF key for 10 seconds (See Figure 3-41). All cooling functions for that zone will begin and the
zone compartment temperature will be displayed in the left display area of the LCD and the right display area will
show the thermistor location.
NOTE: If a COLDER and the UNIT ON/OFF keys are pressed and held for less than 10 seconds, Diagnostic Mode
will be initiated. This was covered earlier in the section.
NOTE: It is possible to toggle through the other temperature readings as in Diagnostic Mode, but in this case the
temperature readings will last for 5 minutes rather than twenty seconds.
NOTE: The compressor overload could prevent the compressor from energizing.
NOTE: Manual Component Activation Mode will end 5 minutes after it is initiated. It is possible to end this 5 minute
run time and return to normal operation by switching the unit OFF then back ON. If this is done, note that the elec-
tronic control will observe a 3 minute minimum compressor OFF time when the unit is switched back ON. This is to
protect the compressor and its electricals.
