OPERATION

2.1

Element Duty Cycles

A new PID algorithm controls the way in which the elements cycle on
and off during each cooking mode duty cycle. Every minute, the oven
temperature is compared to the set point and a recalculation occurs,
which results in varied element cycle times rather than the standard
fixed 60-second cycle.
During Preheat, however, a 2-point control is still used and there is a
defined element on-time. The following table reflects the duration and
start point by Preheat mode, for cavity types A, B, and C.
Technicians should have ample time to troubleshoot element
problems during the ~10-minute preheat period.
