Turbo Chef Technologies Residential Single and Double Wall Oven Convection System Lower Oven

5.2OVEN SYSTEMS

Convection System - Lower Oven		For Gen 2 ovens, operation is the same through the
(Double Wall Oven Only)		CookWheel, but power is received from terminal
		RBJ20-2 of the relay board.
The lower oven convection system is designed to
rapidly heat and recirculate air into the cook cavity.		Speedcook Oven Door

output “A” while the L2 voltage is controlled by the

		follow the steps below. Refer to Figure 5.1.

Bake Element

The bake element’s L1 voltage is controlled by the K11 solid state relay’s output “B” while the L2 voltage is controlled by the K13 relay’s N.O. terminal.

Convection Element

The convection element’s L1 voltage is controlled by the K11 solid state relay’s output “A” while the L2 voltage is controlled by the K13 relay’s N.O. terminal.

Convection Fan

The convection fan motor is powered by 120 VAC L2 voltage, which is controlled by the selector switch’s terminal “3.” When a convection cycle is selected, the switch to terminal 3 is closed and the convection fan motor is supplied voltage. The convection fan will continue to run until the selector switch is turned to a non-convection cycle and the switch to terminal 3 is opened.

CAUTION: DO NOT lift the oven door by the handle. Lifting the oven door by the handle can damage the oven door and cause it to misalign.

1.Ensure the oven has cooled to at least 160°F (71°C).

2.To gain access to the right and left upper-hinge pockets, remove the oven from the cabinet approximately 7” (178 mm).

3.Remove the insulation covers (1) and insulation (2).

4.Remove the locking screw (3) from the receivers (one on each side).

5.Open the door completely.

6.Pull both hinge locks forward.

7.Raise the door until the hinge locks prevent the door from closing any further.

8.Hold the door by the sides and lift the door out of the hinge pockets.
