Self Diagnostics
To enter Self Diagnostic mode, both temperature control panel displays must be illuminated. A display
can be illuminated by pressing an adjacent temperature adjustment button. When both displays are
illuminated, set the freezer and refrigerator temperature settings to 5. Simultaneously press and hold all
4 temperature adjustment buttons for approximately 3 seconds. A flashing 0 in the refrigerator and
freezer displays will indicate that the refrigerator is in Self Diagnostic mode.
For temperature control panels with single-digit displays, the COLDER temperature adjustment button
will increment the numbers up and the WARMER temperature adjustment button will increment the
numbers down. Use the freezer temperature adjustment buttons to enter the test code number in the
freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in
the refrigerator display. When a test code has been entered, the displays will flash to confirm the test.
Press the HOLD button for 3 seconds to begin the test.
For temperature control panels with 3-digit displays, the COLDER temperature adjustment button will
increment the numbers down and the WARMER temperature adjustment button will increment the
numbers up. Use the freezer temperature adjustment buttons to enter the test code number in the
freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in the refrigerator display. When a test code has been entered, the displays will flash to confirm the test
code. Press any button other than a temperature adjust button to begin the test.
When testing has been completed, do one of the following things:
• Enter code 1 5 to completely reset the system.
• Enter code 1 6 to exit diagnostic mode.
