ELECTRONIC CONTROL DIAGNOSTIC MODE AND COMPONENT TESTING
The Jenn-Air Ovens provide a Diagnostic program
that can help diagnose concerns with the oven.
The diagnostic program will need to be accessed
anytime the User Interface or Control Panel
Assembly is replace because the Oven Cavity
size (27 or 30”) needs to be programmed into
the control.
The Diagnostic Mode will provide Error Code
information, and the ability to clear error codes
from the control memory. It can help activate
the Appliance Manager relays for diagnostic help
and, as mentioned before, provide the process
for selecting the oven cavity size anytime the
User Interface or Control Panel Assembly is
replaced.
