5With the combi in the Hot Air mode with time on the timer, the door closed and the start switch is depressed
b The front display will include a lighted bar under the Hot Air symbol
•When the heat circuit is energized the heat symbol will be energized
•The cooking mode symbol will be energized.
•The time display will invert and begin to count down.
cThe fan circuit is energized by the Control Board (A10) transmitting and receiving a signal from terminals 5,6,7 and 8 on connector X10 to terminals 3,4,5 and 6 of connector X28 on the Gas Board (A20)
dThe Gas board (A20) Transmits a signal from terminal 4 of connector X26 to the Motor Drive.
•The motor Drive Board sends a signal through the thermal switch in the motor from Terminal 5 and receives on terminal 6
•If the thermal switch is not open the Motor Drive Board (U10) sends 240 VAC 3 phase to the motor.
•The motor reverses direction every 120 seconds with a 15 second coast.
•NOTE: If the set temperature is less than 212 degrees F than fan will be pulsed on for 2 seconds every 60 seconds after the cabinet set temp (B6).
eHot air heat circuit is energized
•A signal is sent from terminal 2 of connector X24 on the Gas Board (A20) to terminal 4 of connector X2 on the Hot Air Power Burner and Fan Control (U20) selecting the set speed of the combustion blower.
◊When this speed is attained the signal is sent from terminal 2 of connector X2 on the Hot Air Power Burner and Fan Control (U20) to terminal 3 of connector X24 on the Gas Board (A20)
•A request for heat is sent from terminal 3 of connector X20 on the Gas Board (A20) to terminal 10 on connector X1 on the Hot Air Control Module (N20)
◊24 VAC is sent from terminal 2 of connector X2 on the Hot Air Control Module (N20) to the hot surface igniter (R20).
◊The gas valve is energized allowing gas and air into the burner chamber to be ignited by the hot surface igniter.
◊The Hot Air Burner Control Module (N20) senses at least 1.5 micro amps DC from the flame sensor (P1) at terminal 3 of connector X2 and sends a signal from terminal 2 of connector X1 to terminal 10 of connector X25 on the Gas Board (A20
