Convection Pre-Heat Mode
Convection Mode
Sequence of events:
1)
K4, K10, K11 relays close.
2)
K4 relay energizes both cooling motors; airflow from cooling motor
closes the “air switch” contacts. The completed “air switch” circuit signals
the board {signal voltage). Note: if the air switch circuit is not completed
within 40 seconds, the board will interpret an cooling fan fault and
display an F34 error code for the upper oven, and an F64 error code for the
lower oven.
3)
K11 relay closes and activates the convection motor. Note: the convection
motor will stop when the oven door is opened during any convection
mode.
4)
Pin header P14 on the relay board sends 24 VDC to the double line break
relay (DLB) coil. When the coil is energized; the DLB contacts close.
Current flows from L1 to one leg of the bake, broil, and convection
element
5)
Convection relay K10 closes and sends current from L2 to the other leg of
the convection element. The convection element is on for 60 seconds
during each 1-minute cycle.
