System status
indicators
The front panel of the oven contains the system status indicator (Figure 10) . Yellow
indicates that the set point has not yet reached the set value. Green indicates that the
set point has been reached and that the oven is operating normally. The indicator
monitors the following items:
• Normal – the green indicator illuminates when the oven temperature is near its
programmed set point.
• Heating – the yellow indicator illuminates whenever Normal status has not yet
been achieved. When started cold, this indicator will remain illuminated while
the oven is warming up (typically about 30 minutes).
• Error – the red indicator illuminates if a functional error has been detected. An
audible alarm will sound and an error code will appear on one of the
alphanumeric displays. For example, if the oven doesn't reach temperature in a
reasonable amount of time, you will get an E02 error and a red Error light. Refer
to the section, "Error codes and troubleshooting" on page 21 for a list of error
codes and their meaning.
• Door Open – the red indicator illuminates whenever the door is open. When the
door is open, the rotisserie will stop and the heater will shut off. When the door is
closed, both functions will resume.
