Using Table 3 (Element Duty Cycles During Preheat) - Thermador Masterpiece ME271E Series Service Manual

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 table below 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.

2.1.1 Using Table 3 (Element Duty Cycles During Preheat)

In Table 3, Duration is defined as the number of seconds an element
is turned on (e.g., 12 indicates the element will be on for 12 seconds.)
Start Point is defined as the point in the cycle at which the element will
turn on (e.g., 30 indicates the element will turn on in the 30
of the cycle).
Using the data in the table, below is an example of how the elements
cycle on and off during a 60-second Preheat cycle in True
Convection mode (see Cavity C):
ME302ES built in 01/2008 (see columns labeled 1)
•
Bake Element: After initial 30 seconds of the cycle, element
turns on and remains on for the final 30 seconds of the cycle.
•
Ring Element: After initial 30 seconds of the cycle, element
turns on and remains on for the final 30 seconds of the cycle
(same as Bake Element).
•
Broil Element: Turns on at the beginning of the cycle (0) and
remains on for the first 30 seconds of the cycle.
ME302ES built in 08/2008 (see columns labeled 2)
•
Bake Element: After initial 33 seconds of the cycle, element
turns on and remains on for the final 27 seconds of the cycle.
•
Ring Element: After initial 36 seconds of the cycle, element
turns on and remains on for the final 24 seconds of the cycle.
•
Broil Element: Turns on at the beginning of the cycle (0) and
remains on for the first 27 seconds of the cycle.
In Fast Preheat (available in cavities B and C with convection fan), the
same elements reflected in the table are used, but the broil element is
on ~10% longer, and the convection fan stays on as well.
It is important to note that during regulation (regular cooking period
that follows Preheat), different elements may be used and element
duty cycles will vary.
