Diagnostics & Troubleshooting - Whirlpool JOB AID GC1SHAXM Installation And Operation Manual

DIAGNOSTICS & TROUBLESHOOTING
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
Diagnostics on this product are different than
on other Whirlpool SxS refrigerators. Several
error codes are available, however there is no
"diagnostic mode" that can be "entered" on the
electronic control to allow operation of each
function separately.
Virtually all functional component testing must
be performed similarly to a non-electronic
product by verifying whether the component
is "good," or whether there is voltage present
at the component. To know how these com-
ponents function in this product, refer to the
"Theory of Operation" section and the contents
of this section.
IMPORTANT INFORMATION
Electronic Control Board
• Virtually all components and functions are
electrically connected to and controlled by
the Electronic Control Board both on the
"line" and "neutral" side. The exception is the
ice dispenser motor and the dispenser light.
These components are directly connected
to and controlled by the User Interface.
WARNING
Electrical Shock Hazard
• The majority of components and functions
controlled by the Electronic Control Board
are switched on the "neutral" side of the
circuit. This means the "line" side of the
circuit to the component(s) always has
voltage potential.
User Interface Control Board
• The User Interface Control Board is also
energized by "line" and "neutral" circuits
through the Electronic Control Board.
Communication between the two boards
is through the "TX" and "RX" circuits (refer
to the Wiring Diagram and Strip Circuit).
• Turning OFF the refrigerator turns off all of
the interior and indicator lights except two
dots (".") in the temperature displays.
