GE JS760 Service Manual

Fault Retrieval Mode
Service technicians have a couple of methods for interfacing to the control to aid in finding root
cause to Fault Codes. This is either from using the NewFI tool or from using a separate mode
in the RC15, the Fault Retrieval mode. The following describes the Fault Code Retrieval mode.
Note that this can also be a consumer facing mode for the user to save a call and communicate
issues to a Service Technician

The Range should not enter Fault Retrieval mode if the oven is active.

The user can access Fault Retrieval mode during Fault Display
 Mode is activated by pressing the 1+3+0 keys simultaneously for 3 seconds

If there are no faults present in the system, then "nonE" will be displayed on the Time
Display

"nonE" will also display if 1 or 2 key is pressed when no faults are present.

If Wingboards are not part of the system, display will blank out for respective key
presses for Wingboard Version Number.

Format of Fault in SSDs shall be:
Left Temperature Display: Number of occurrences.
Time Display: Fault number
Right Temperature Display: Status ("Act" for currently active, or "Clr" for not active)
The following defines RC15 key actions while in Fault Retrieval mode:
Key Action

temperature
display "_XX", Critical Minor in the hours digits of the Time Display "XX_ _", Non-critical
Major in the minutes digits of the Time Display "_ _XX", Non-critical Minor in the first two
digits of the Lower temperature display "XX_") in decimal notation
4 Display RC15 Parametric version (Critical Major in the last two digits of the Upper
