Thermador C271 Service Manual - Wire Harnesses
The “C” oven uses 5 wire harnesses to transfer signal voltage between the
DAC control (relay board), display head, and touch control boards (glued
on the glass). The 5 wire harness’ connect to the corresponding pin
headers on the corresponding components (relay board, display head,
touch control board). These 5 wire harness’ are identified as follows:

2 Wire White Power Harness:
This wire harness has 2 wires and connects from
pin header P8 on the display head to pin header
P2 1 on the left touch control board. The center
hole of the connector is plugged so it cannot be
mis-wired. This harness sends 24 volts AC. To
the touch control boards.
7 Wire White Bridge Harness:
This 7 wire harness connects from pin header P2
on the left side TCB to pin header P2 on the right
side tcb. The #2 hole on the connector housing is
plugged (there is no wire). This harness sends
commands between the left tcb and the right tcb.
8 Wire Yellow Display Harness:
This 8 wire yellow harness connects from pin
header P10 on the display head to pin header P10
on the relay board (right rear corner of relay
board). This harness sends display signals from
the relay board back to the display head.
9 Wire Orange Communication Harness:
This 9 wire harness connects from pin header
P11 on the display head to pin header P11 on the
relay board (right front comer of board). This
harness sends communication signals from the
display head to the relay board.
18 Pin White Communication Harness:
This split wire harness has 18 wires and connects
from pin header P1 on the large left side tcb to
pin header P1 on the display head. The side with
the single connector goes to the display head; the
side with the split (2) connector housings goes to
the left side TCB. This harness sends communi-
cation from both the left and right TCBs to the
display head.
