Cu r rent Flow And Ope ration
LOWER OVEN CONVECTION BAKE
• Relay switch E13 to the normally open switch (Relay SPDT) closes in preheat and remains
closed for 12 seconds out of every 60 seconds during temperatures less than 200 degrees.
During preheat temperatures above 200 degrees, relay switch E23 to the normally open
switch (Relay SPDT), remains closed for 20 seconds out of every 60 seconds. After preheat
the relay switch remains open.
• During temperatures less than 200 degrees, relay switch E13 to E12 closes during preheat
and remains closed for 40 seconds out of every 60 seconds. After preheat, and while
temperature is less than 200 degrees, the relay switch will remain closed for 30 seconds out
of every 60 seconds.Temperatures above 200 degrees, the relay switch will remain closed 15
seconds out of every 60 seconds.
• Relay switch E11 to E14 closes and remains closed during this cooking mode.
• Relay switch E7 to E6 closes and energizes the Convection Motor.
LOWER OVEN CONVECTION ROAST
• Relay switch E13 to the normally open switch (Relay SPDT), closes in temperatures below
200 degrees, and will remain closed for 12 seconds out of every 60 seconds. In temperatures
above 200 degrees it remains closed until preheat is complete. After preheat, the relay
switch will remain closed for 20 seconds out of every 60 seconds.
• During temperatures below 200 degrees, relay switch E13 to E12 will close in preheat for 40
seconds out of every 60 seconds. After preheat the relay remains closed for 30 seconds out
of every 60 seconds.
• Relay switch E11 to E14 remains closed during this cooking mode.
• Relay switch E7 to E8 closes in temperatures above 200 degrees. This energizes the K2 relay.
• Relay switch E7 to E6 closes, which energizes the Convection Motor.
LOWER OVEN CLEAN
• Relay switch E13 to the normally open switch (Relay SPDT), will close during preheat. After
preheat, the switch will remain closed for 45 seconds out of every 60 seconds.
• Relay switch E13 to E12 will close after preheat. The switch will remain closed for 15
seconds out of every 60 seconds.
• Relay switch E7 to E8 will close. This will energize the K2 relay. Also, the "DRLK" is closed to
operate the lock motor, which opens LK1 and closes LK2
