Roast Mode
Sequence Of Events:
1) K4, K8, K9 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 a cooling fan fault and display an F34 error code.
For the upper oven, and an F64 error code for the lower oven,
3) 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
elements.
4) Bake relay K8 and broil relay K9 alternately open and close and send
current from L2 to the other leg of the bake and broil elements, this
completes the 240-volt circuit, the bake element is on for 48 seconds, and
the broil element is on for 12 seconds during each 1-minute cycle.
