Troubleshooting Guide

Statistics

1. Enter into Statistics by first entering Diagnostics Mode and choosing Statistics from the Service Menu
(Key Press of 5)
2. Throughout the duration of statistics, the Upper Information Line will display: "Statistics".
3. For the case of a double oven, the upper oven will be addressed until the "UPPER/LOWER" key is pressed.
Pressing this key at any time during Statistics will toggle the selected cavity and set the state to the "Last 5 func-
tions" initial menu. If single oven configuration, an invalid beep will be generated and no change will occur.
4. The ENTER key will cycle through the first level of the statistics.
5. To see the last 5 functions of the unit, user will press the "SET TIMER" key from the "Last 5 functions" initial
menu and the details of each mode will be displayed as the user chooses. Once in the level that displays the
data, the ENTER and CLEAR keys will operate per their default definitions.
6. If the data record for one of the "last 5 modes" has a bad checksum or is empty, "No Mode" will be displayed in
place of the mode name, and the data for all items will be 0 if viewed.
7. To see the total # of cycles of each mode, when user is on the "Total # of each individual..." screen, any key
press of the mode keys will display the # of cycles for that mode. Once in the level that displays the mode count,
the ENTER and CLEAR keys will operate per their default definitions. In addition, pressing one of the mode
keys from this level will jump directly to that modes' display.
8. To exit mode
a. LOCK key will bring user back to the initial Service Menu.
b. The OVEN OFF (UPPER OFF/LOWER OFF) keys will also exit mode and return the display to TOD screen.
c. Or a CLEAR key press from the initial state (unit operation time) will return user back to the initial Service
Menu.
d. No Key press for 5 minutes.

Error Priority

Error codes are organized in a priority-based scheme which allows for different behavior based on the priority of the
error. There are three priority levels, defined as follows:
Priority 1: These errors are considered safety related or of such catastrophic scope that the control is considered
inoperable. These errors will be continuously displayed to the end user, indicating that a service call is required.
No user functions will be allowed, and any active functions will be cancelled upon generation of the priority 1
error. The error can be canceled, but will re-generate if the condition which caused the error still exists.
Priority 2: These errors will be displayed to the user only during an active cooking/clean mode, or upon an attempt
by the user to enter a cooking/clean mode. The criteria for these errors is that they are likely to limit the proper
functionality of the system and would normally cause some customer dissatisfaction. These errors can be can-
celled and will not be displayed again until the user again attempts to start a mode. Any active function in the
cavity for which the error has scope will be cancelled upon generation of the priority 2 error.
Priority 3: These errors are defined as errors which could cause some possible or conditionally impaired functionali-
ty, most likely to be never noticed by the end user. These errors, although logged internally, will never be dis-
played to the end user, and are generally not cancelable by the end user.
