Figure 3-46. Initiate Manual Component Activation Mode -
Press and Hold Desired COLDER Key and UNIT ON/OFF Key for 10 Seconds
Manual Component Activation Mode
Manual Component Activation Mode energizes a cooling system for 5 minutes. When activated, the chosen com-
partment’s compressor and evaporator fan are energized along with the condenser fan. While in Component
Activation Mode, the evaporator temperatures for that compartment are displayed on the LCD. This mode also
allows the Service Technician to check for proper voltage readings at the activated components without having to
wait for the compartment to call for cooling.
To initiate Manual Component Activation Mode, the unit must be ON, then press and hold the desired compartment
COLDER key and UNIT ON/OFF key for 10 seconds (See Figure 3-46). The evaporator temperature for that com-
partment will be displayed in left display area of the LCD and the right display area will show the thermistor location.
NOTE: If the COLDER and UNIT ON/OFF keys are pressed and held for less then 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 20 seconds.
NOTE: The compressor overload could prevent the compressor from energizing.
NOTE: Manual Component Activation Mode will end 5 minutes after 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 electronic
control will observe a three minute minimum compressor OFF time when the unit is switched back ON. This is to
protect the compressor and its electricals.
Press and hold for 10 seconds
Clearing Error Codes
If error codes are observed in diagnostic mode, a non-flashing
SERVICE indicator will appear on the LCD when
Diagnostic Mode ends, indicating error codes are still logged (See Figure 3-44). To clear a non-flashing SERVICE
indicator and the error codes, the problem must be corrected and the unit must be ON. Then, the Bell ON/OFF key
must be pressed and held for fifteen seconds. The control will emit a short “beep” when the SERVICE indicator and
error codes are cleared. (See Figure 3-45)
