Broil Pre-Heat
Broil Mode
Sequence Of Events:
1) K4, 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 an 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
element.
4) Broil relay K9 closes and send current from L2 to the other leg of the broil
element. The broil element is on for 60 seconds during each 1-minute
cycle.
