71 SERVICE REQUIREMENTS
1.1 Health & Safety
Note: When servicing the wall oven, Health and Safety issues must be considered at all times. Specic safety
issues are listed below with their appropriate icon. These are illustrated throughout the service
information to remind service people of the Health and Safety issues.
1.1.1 Electrical Safety
Ensure the mains power has been disconnected before servicing the wall oven. If the
supply is required to be on to service the oven, make sure it is turned o when
removing any electrical component or connection to avoid electrical shock.
1.1.2 Electrostatic Discharge
An anti-static strap is to be used as electrical static discharge (ESD) protection when
servicing electronic components.
1.1.3 Good Working Practices
Ensure the work area is in a tidy and orderly condition at all times so as not to cause a
hazard while service work is being completed. Always clean and tidy the oven and work
after service is completed.
1.1.4 Insulation Test
Megger test to check insulation.
Warning: Short together the phase and neutral pins on the plug so as not to damage any
electronic circuitry.
1.1.5 Sheet Metal Edges
When working around cut sheet metal edges use appropriate gloves or protection to
eliminate the chance of receiving a laceration.
1.2 Specialised Tools
For servicing this product, specialised tools are required.
1.2.1 Static Strap
To be used as ESD (electrostatic discharge) protection when replacing or handling
electronic components.

2.2 Cabinetry Dimensions
Important!
Some environmental factors and cooking habits can cause condensation in and around the oven during use. To
protect surrounding cabinetry from possible damage caused by frequent or excessive condensation, we recommend
moisture-proong the oven cavity.

11 3 TECHNICAL OVERVIEW
3.1 Model Number Description, Product Codes & Service Versions
E.g. OB60SC7VEX1
Type OB = Oven Built In
Width 60 = 60cm
Cavity B = Double Cavity
H = Double Under Bench
N = Compact Oven
S = Single Cavity
L = Large Cavity
Functions 7 = 7 Oven Functions
Family C = Classic
D = Designer
L = Commercial
V = Exclusive
Features E = Electronic clock
M = Electronic Minute Timer
T = Soft Touch Control

Series 1 = 1st Iteration
The product code is a dedicated number used to identify model variations e.g. dierent colour, market
etc.
e.g. :80831 -A is a single stainless steel, AA product. The -A relates to the service version of the product.
The Service version is used to signify that some new components or features are not retro-table to
earlier product versions.
e.g. 80831-B uses a number of dierent parts (which are contained in a separate parts manual) to 80831-
A, so is important to only order parts for the correct product code with correct service version.

3.3 Oven Cavity Fan
The oven cavity fan turns on as soon as the mode is
selected.
The fan should always operate when the fan element is
on.
Voltage: 230 V
Wattage: 30 watts
3.4 Cooling Fan & Venting System
The cooling fan specications
Voltage: 230 240 V
Frequency: 50 HZ
Wattage: 14 watt
The venting system allows a small amount of air to ow through the cavity from an inlet at the left rear, to
an outlet in the top. The outlet air is ducted to the cooling fan and then expelled.

14
The outlet vent sits in the top right of the cavity liner, this carries the vapours up through the duct to the
cooling fan and is then expelled.
These models have valves on the inlet and outlet vents. The valves are operated by wax actuators and
are driven by the oven controller. This allows the venting rate to be customised to suit the oven function
being used by the customer, and helps eliminate condensation.
The Pyro version includes a catalytic converter in the outlet to reduce smoke and CO during a self clean
function.
High Spec Multi and Pyro
Inlet Valve
Outlet Valve

15
The micro switches are activated by a cam, which
tells the PCB when the door is‘unlocked’ or‘locked’.
The board needs to see a ‘locked’ signal for the
pyro cycle to work and an ‘unlocked’ signal for the
cooking functions to work. The stoppers are used
to stall the motor to force it to change direction.
The start-up direction of the motor is random so
if it starts in the wrong direction the stoppers are
used to reverse it to go the right way.

3.10 OB60 Clock Module
3.9 OB60 Function Switch
The OB60C model only uses a
mechanical type thermostat.
The thermostat is used to switch the
oven element on and o to maintain
temperature.
3.8 OB60 Mechanical Thermostat
The function switch is only used in OB60
models, and is used to select the oven
functions.
The function switch has 7 functions.
when switched on will operate the light in the
oven as well.
Refer to product wiring diagram on page 60
Some OB60 models use a clock module which is
a user interface display.
This module shows the time, and allows the user
to select automatic cooking and a cook timer.

3.11 Temperature Module
The OB60C models use a display module as a
customer interface to show cooking temperature.
This temperature is illuminated and shown on the
control panel.
The module uses a harness to communicate with
the clock module, and has an encoder for the
customer to select temperature.
The module also has LED lights which show red
while heating, and turn white when the oven is at
the correct temperature.
3.12 Function Module
The OB60C models use a function module as
a customer interface, and shows the cooking
function selected by illuminating the icon on the
control panel.
The module uses a harness to communicate with
the clock module, and has an encoder for the
customer to select the oven function.
The module also has an illuminated white halo
around the control knob.
3.13 User Interface Harness
The temperature and function modules are
linked to the clock module via the user interface
harness.
This harness uses knob encoders for the
customer interface for selecting the oven
function or selecting the oven temperature.

19
3.14 Limiters
All models have a fan run on limiter which is set
to 55 deg C.
This limiter will keep the cooling fan running until
the cavity temperature drops below 55 deg C.
The over temp limiter is one shot type Honest
Well TY24, the trip temperature is 110 deg C. refer
to parts manual.
3.15 Power Board
The power board is located in the top panel area,
and is held in place by clips.
The power board is connected to the clock via a
harness and controls the following components:
• Elements
• Door switch
• Temperature sensor.
• Door lock (pyro model only)
• Lights
• Rotisserie motor
• Cavity fan
• Cooling fan
The power board is a GOEP type board so is used
in both the pyrolytic model and multifunction
model. This means if being changed for any reason,
the model ID must be selected for the product it is
being tted to.
Refer to section 6 for more detail.
