Introduction - GE GSS20 Series Technical Service Manual

2001 Energy SxS models are being introduced in
response to the requirement for more energy-
efficient refrigerators by mid year 2001, along with
having feature and operation enhancements. The
primary differences in this refrigeration system are
the adaptive defrost system (see Pub. # 31-9062),
control board, software, and control systems that
operate independently in fresh food and freezer
sections. The new high-efficiency control system
has the ability to cycle components and adjust fan
speeds as required to maintain temperature-
setting ranges in freezer and fresh food sections.
Feedback systems are digital inputs and relay
outputs. Sensors (thermistors) are used to
measure temperature with communications to a
main PC board, which controls the unit
components. The refrigerator has versions that
have control knobs or touchpads (Profile models)
to provide inputs to a microprocessor. The freezer/
fresh food controls are temperature setpoint type
and have settings of 0-9 with 9 being the coldest
temperature possible. The new NO CLEAN
condenser is serviceable from the rear and is
designed to prevent the customer from having to
clean the condenser in normal usage conditions.
Sealed system operation and compressor are
functionally the same as previous models, with
some minor changes.
The 20', 22', and 25' side-by-side models are the
models affected. These models are available with
through-the-door chilled water and ice dispenser,
and built-in water filter feature. On models
requiring icemaker, the newest electronic
icemaker (see Pub. # 31-9063) has been or can
be installed.

Introduction

The freezer has adjustable shelves, slide-out
Spillproof shelf, QuickSpace shelf, and deep door
shelves, based on model. The fresh food section
has a baking soda holder, fruit and vegetable
drawer, drawer dividers, adjustable humidity
drawer, and convertible meat drawer.
This new high-efficiency refrigerator is a
combination of the most efficient refrigeration
system and the most desirable customer features
available.
