Alphanumeric Codes-900 Series - Norcold 9182 Service Manual & Parts List

Description of Alphanumeric Codes for 900 Series (Diagnostic Indicators)
The refrigerator's operating control is equipped with Alphanumeric Codes which assist the service technician in trouble
shooting and alert the refrigerator owner to a problem in any mode of operation. When a problem occurs within a given mode, the
operating controls will revert to a stand-by mode in which an alarm will sound and a two digit alphanumeric code will be displayed in
the center control window. The alarm will sound until an alternate operating mode is selected. The alphanumeric code will continue
to be displayed until the controls are turned off and then back on or until the problem is corrected. Diagnostic codes which begin
with A indicate a minor problem that may usually be corrected by the refrigerator owner. Diagnostic codes beginning with C or D
indicate faults which are not owner serviceable but instead require service from a qualified service technician. Codes and their
meanings begin below.
