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.
To perform a self diagnostic test, locate the test in Table 2, Diagnostic Tests.
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. The temperature control panel is reset automatically.
⢠Unplug the refrigerator for at least 10 seconds. Test mode will terminate when the refrigerator is plugged back in.
Test mode will terminate automatically after 15 minutes of inactivity.
(or in your case.... after the deforst cycle completes and possibly + 15 minutes)
