5.2 OVEN SYSTEMS
For Gen 2 ovens, operation is the same through the
CookWheel, but power is received from terminal
RBJ20-2 of the relay board.
Speedcook Oven Door
Th is section contains information about the
following:
- Removing/reinstalling the Speedcook oven door
- Door skin replacement
- Left lock motor assembly
- Right lock motor assembly
- Measuring RF leakage for microwave safety
- Halogen light assembly
For information on accessing and removing parts,
and for part numbers, see the Appendix.
Th e proper fi t and adjustment of the oven door is
essential for safe and reliable oven operation.
Removing/Reinstalling the Speedcook Oven
Door
To remove or reinstall the Speedcook oven door,
follow the steps below. Refer to Figure 5.1.
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.
Convection System - Lower Oven
(Double Wall Oven Only)
Th e lower oven convection system is designed to
rapidly heat and recirculate air into the cook cavity.
Th
is section contains information about the
following components:
- Broil element
- Bake element
- Convection element
- Convection fan motor
For information on accessing and removing parts,
and for part numbers, see the Appendix.
Broil Element
Th e broil element consists of independently-operated
inner and outer elements. Th e inner broil element’s
L1 voltage is controlled by the K12 solid state relay’s
output “B” while the L2 voltage is controlled by the
K13 relay’s N.O. terminal. Th
e outer broil element’s
L1 voltage is controlled by the K12 solid state relay’s
output “A” while the L2 voltage is controlled by the
K13 relay’s N.O. terminal.
Bake Element
Th e 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
Th e 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
Th e 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. Th
e
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.
