The purpose of this section is to familiarize the service technician with operation of the user interface and proper
function of the electronic control system. This section explains all electronic controls and diagnostics for the unit
with the exception of ice maker controls. Ice maker controls operation is detailed in the “Ice Maker” section.
There are two standard user interface controls available with dispenser equipped models: Express-Select

(See Figure 3-1 and 3-2).
The user interface for non-dispensing models is an Express-Select
™
control (See Figure 3-3). The control layout
is different from the dispenser model
Express-Select
™
control user interface in Figure 3-1, but functions of the
corresponding selections are the same unless otherwise noted. See page 3-4 for details.
