OVEN SYSTEMSAND COMPONENTS
Convection System
The convection system is designed to rapidly heat,
clean, and recirculate air into the cook cavity. See
page 41 for a schematic.
The convection system consists of the following
components:

Blower motors

Blower motor speed controllers

Heaters

Jetplates

Jetplate support rails

Oven rack

Rack oscillation motor

Swing arm assembly
Blower Motors
The convection motor is a brushless AC switch
reluctance type. Its top speed is 7100 RPM at 1
HP. The motor is controlled by a proprietary
controller, spins counterclockwise, and can be
tested on the service screen (page 16).
Blower Motor Speed Controllers
The blower motor speed controller (BMSC) is
proprietary and will only operate the convection
motor described above. It is controlled via 0-10
VDC speed command from the control board. The
BMSC can be tested on the service screen by test-
ing the blower motors (see page 16).
Heaters
There are two convection sheathed-style heaters for
each cavity. Each heater is rated at 3000 watts at
208 VAC with a resistance of 14.4 ohms. The heat-
ers are controlled by the K5/K6 (top cavity) and
K7/K8 (bottom cavity) solid state relays. The heat-
ers can be tested on the service screen (see page 16).
Jetplates
The jetplates channel air from the blower motor
into the cook cavity. Different hole patterns are
available for custom cooking results; contact
TurboChef for more details.
Jetplate Support Rails
Each jetplate is supported by two rails. These rails
must be removed prior to replacing or removing
the jetplate for cleaning (see pages 5-8 for detailed
cleaning instructions).
NOTE: Some models may not include support rails.
Oven Rack
The oven rack sits on two pins and oscillates to
help ensure even cooking.
Rack Oscillation Motor
The rack oscillation motor actuates the swing arm
assembly, which causes the rack to oscillate. The
motor can be tested on the service screen (see page
16).
Swing Arm Assembly
The swing arm assembly consists of two arms con-
nected by a link bar beneath the oven cavity. It is
actuated by the rack oscillation motor.
