10 TROUBLESHOOTING
The information in this section will be helpful when troubleshooting, diagnosing, and resolving faults and other issues affecting the normal operation
of the oven in the range. Please refer to the cooktop Failure Codes and Service Programs in QuickFinder.
10.1 Error Codes
A Service Guide/Wire Diagram that includes error code information is available in QuickFinder and is also packed with
every range. Separate diagrams for the induction cooktops are also packed with each range. Find them in a pouch taped
to the rear vented panel, as shown in Figure 33.
Additional error code information and suggested repair actions can be found in the following table. Note that error codes
which begin with E1 apply specifically to the oven cavity, and those which begin with E2 apply specifically to the
