MODEL 427R-2 REFRIGERATOR SECTION SERVICE INPUT OPERATIONS
Model Configuration Mode
The main control board is used in several different models, so when a 427R-2 Unit is manufactured, the main control
board must be configured/programmed by a series of key strokes at the control panel. This is called Model
Configuration.
If a new main control board is installed during a service call, double dashes ( - - ) will appear on the LCD (See
Figure 3-85). This indicates the board must be configured for the model it was installed into. This is accomplished
in Model Configuration Mode, which is entered as soon as power is supplied to the unit. While in this mode, open
the bottom drawer, then toggle through the model codes by pressing the WARMER or COLDER keys, until proper
model code is displayed (See Figure 3-86 and 3-87, and Model Code Table below). With proper model code dis-
played, press UNIT ON/OFF key to lock the model configuration (See Figure 3-88).
