Diagnostic Aid; Troubleshooting - GE GSS20 Series Technical Service Manual

Diagnostic Aid

Note: Not all diagnostic tests are available on all
models. See Diagnostic Chart, on next page, for
details.
The purpose of the diagnostic aid is to allow,
through a touch control board, the operation of
individual components and test circuits on
electronic refrigerators that do not contain built-in
diagnostics. This includes all electronic models
with a 4-pad touch control and electronic models
with temperature knobs.
The following 3 parts are required to assemble the
diagnostic aid:
• WX05X14999 Wiring harness
• WR55X10092 Temperature control board
• WR55X10068 Touch control membrane
and housing
Mount the temperature control board in the touch
control housing and connect the ribbon cable.
Connect the long (single connector) end of the
test harness to the J2 connector on the
temperature control board.
)
Connect the other end of the test harness to the
refrigerator using the appropriate plug for the
model being tested.
Note: On steel liner models with a 4-pad
temperature control (no filter reset), you must
disconnect the original touch control and plug the
cabinet harness directly onto the diagnostic aid
control board.

Troubleshooting

Enter the diagnostic mode by pressing both the
freezer temperature (colder and warmer) pads
and the refrigerator temperature (colder and
warmer) pads simultaneously.
Note: All 4 pads must be held for approximately 3
seconds. A blinking "0" in both displays indicates
the refrigerator has entered the test mode.
