Manual Entry Model Configuration Mode

Manual Entry Model Configuration Mode allows a Service Technician to verify a main control board of the 427R
refrigerator section was configured correctly, and/or to reconfigure the main control board if a mistake was made
during the configuration process.
To initiate Manual Entry Model Configuration Mode the unit must be ON and the bottom drawer open. Then, Press
and hold the drawer ajar alarm bell ON/OFF key and the UNIT ON/OFF key together for 15 seconds. The unit will
now be in Model Configuration Mode, with the model code of the last configuration displayed (See Figure 3-89 and
Model Code Table on previous page). If needed, toggle through the model codes by pressing WARMER or COLD-
ER keys, until appropriate model code is displayed (See Figure 3-90 and 3-91). With appropriate model code dis-
played, press UNIT ON/OFF key to store model configuration (See Figure 3-92).
