Troubleshooting
1. 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 four pads must be held for approximately
3 seconds. Blinking "0's" in both displays indicate
the refrigerator has entered the test mode.
3. Press and release any pad other than the
temperature pads to active the test mode.
4. Enter the display numbers as shown in the
diagnostics chart on the next page for the test
desired.
5. Press and release any pad other than the
temperature pads to active the test mode.
Note:
Selected models have limited test capability.
See the COMMENTS column in the Diagnostics
Chart on the next page for clarification.
Control Diagnostics
A diagnostic aid can be assembled which consists
of a control board, membrane and wiring harness.
The parts required are WR55X10120,
WR55X10068 and WX05X14999.
The control diagnostics allow the technician to
functionally test individual components to aid in
troubleshooting.
On the electronic bottom mount models, the
diagnostics are performed by removing the
existing temperature control board and plugging in
the diagnostic aid or by accessing the main board
on the back of the refrigerator and plugging into the
J4 connector.
Enter the appropriate display numbers
as shown below and press any pad other
than the temperature pads to activate
that test mode. Not all test modes are
available on all models.
