• For the next 2 minutes 220 VAC is sent from terminal 3 on connector X11
through the normally closed auxiliary contacts of contactor K50 to the K5
contactor coil
◊ K5 contactor closes and the motor turns CCW
◊ The normally closed auxiliary contacts on K5 open preventing the K50
contactor from energizing.
• NOTE: If the door switch (S7) opens by the door opening, then the fan circuit
is de-energized. Then the motor will be pulsed in the opposite direction to
“break” the fan. This is to stop the fan quicker for the operator.
c The hot air heat circuit is energized
• 220 VAC is sent from terminal 3 of connector X12 on the Control Board
(A10) to the coil of Contactors K41 and K61 until the cabinet reaches the set
temperature as sensed at probe B6.
◊ The Contactors K41 and K61 close and he 220 VAC is sent to the outer
elements (E41 and E61)
• 220 VAC is sent from terminal 7 of connector X11 on the Control Board
(A10) to the coil of Contactors K42 and K62 until the cabinet reaches the set
temperature as sensed at probe B6.
◊ The Contactors K42 and K62 close and 220 VAC is sent to the inner
elements (E42 and E62)
◊ If the reduced power option is chosen then Contactors K42 and K62 are
not energized.
d When the condensate box is heated to 140 degrees F at the B3 probe, 220 VAC is
sent from terminal 5 of connector X12 to the condenser valve (Y1) until the
temperature drops.
e If the “Crisp and Tasty” mode is selected
• 220 VAC is sent from terminal 6 of connector X12 on the Control Board
(A10) to the Dehumidification Valve (Y2) to pull the humidity out of the
cabinet down the drain.
◊ In the light and medium modes (one and two drops in the display) the Y2
valve will be energized until the bypass probe (B5) is satisfied.
◊ In the full mode (3 drops in the display) the Y2 valve will be energized
continuously.
f When the timer counts to 0 or the core temp probe (B10) reaches the set amount
the cycle ends
5 With the combi in the Combi mode with time on the timer, the door closed and the
start switch is depressed
a The front display will include a lighted bar under the combi 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.
b The fan circuit is energized
• If the combi fan is in the normal setting 220 VAC is sent from terminal 5 on
connector X11 through the normally closed auxiliary contacts of contactor
