Viking Refrigerator Diagnostic Information
Service Diagnostics Mode permits you to determine the firmware as well as software program variations, test status of “design specific” system components and sensors, and also alter state of elements where relevant (i.e.– compressor on/off, and so on.).
Enabling Service Setting: To make it possible for Solution Mode, press and hold the “WARMER” button while pushing the “COLDER” button 4 times within 5 seconds.
After getting in Solution Mode, the very first number that you will certainly see shows the software application version number for the particular unit you are servicing. As an example, if you are servicing a 24 inch wine cellar (DFUW, DUWC, VUWC), the first number you will see is 11. See chart listed below for equivalent design and software program recommendation.
The 2nd number you will certainly see indicates the software variation release. For instance, if you see 44 on the display screen panel it shows software application variation 4.4.
Diagnostics:
While in Service Setting, press the “SET” button to step via Examinations 0-9. The initial number of the display screen will certainly reveal the test number. The 2nd number shows the existing state of each part under test as well as is displayed as “1” getting on, CLOSED, or SHORTED as well as “0” being OFF or OPEN. Examinations 0 and 1 reveal an open or shorted problem identified at the sensing unit inputs. Examinations 2 through 6 permit you to transform loads ON with the “WARMER” switch and OFF with the “COLDER” button. Examinations 7 through 9 validate state modification of the door switches over and/or magnetic reed sensing unit. The element examinations available are described in Readily available Part Tests chart.
