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 mains
supply is required to be on to service the wall oven, make sure it is turned off when
removing any electrical component or connection to avoid electric 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 wall oven and
work area after service is completed.
1.1.3 Insulation Test
Megger test to check insulation.
arning: Short together the phase and neutral pins on the plug so as not to damage any
electronic circuitry.
1.1.4 Sheet Metal Edges
hen working around cut sheet metal edges use appropriate gloves or protection to
eliminate the chance of receiving a laceration.
1.1.5 Diagnostics
hile in diagnostics some safety devices are bypassed. Ensure you do not run
components unattended.
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.

3 MODEL / SERIAL N MBER LOCATION & IDENTIFICATION
The product data label is located on the left hand side behind the grill, between the control panel and
the oven door (top oven on double models).
The data label contains information specific to that model, like product code number, model number,
and serial number.
The product code is a dedicated number used to identify the model variants, e.g. color, markets,
features.
E.g. 71164-A = a DCS-branded double stainless steel model built for the North American market.
The letter shown after the product code signifies the service version of the product. The service
version changes when new parts are introduced to the model which are not backwards compatible.
hen ordering parts, it is very important to use the correct product code and service version. Each
product code / service version variation has a dedicated parts manual. For example, 71164-A will
comprise different parts to 71164-B.

4.1 Oven Cavity Fan
The cooling fan will turn on as soon as the oven mode dial is moved from the ‘OFF ‘ position. It will
turn off after eight seconds if a temperature isn’t selected.
The cooling fan will only turn off if the oven cavity has cooled below 302°F (150°C) after use. If the
oven cavity temperature is above 554°F (290°C), the cooling fan will run at high speed.
During the Self-Clean Cycle, the cooling fan in the cavity being cleaned will run at high speed. The
other cavity will run on low speed (in a double oven).

4.9 Halogen Bulbs
The oven cavity lights will come on when the door is opened or when an oven mode is selected.
The lights will turn off when the door is closed (if no oven mode is selected) or if the programmed
oven cook time has finished.
There are three soft start halogen bulbs in each oven cavity.
Voltage: 12 VAC
attage: 20 watt
The door lock will only operate during the Self-Clean cycle
and is designed to stop the oven door from being opened
when very high temperatures and potentially dangerous
fumes are produced in the oven cavity.
Voltage: 208 – 240 VAC
attage: 40 watt
4.10 Door Lock Motor
The O models use a display module as a customer interface to show oven mode and cooking
temperature. It also displays time of day when set, and is utilized for the auto setting and timer setting.
Temperature and time settings are illuminated and shown on the control panel.
The display module also incorporates push buttons which allow the user to input and cancel time and
menu settings, probe settings, and user preference settings.
The module uses wiring harnesses to communicate with the function and temperature encoders, and
the power board.
4.11 Display Module

16
The O models use encoders as a customer interface for setting oven mode and temperature. One
function and one temperature encoder are provided for each oven. The function encoder is an
absolute encoder, meaning the dial can rotate a full 360 degrees. The temperature encoder is a
jog encoder, rotating 30 degrees left or right and returning to the center position when the knob is
released.
The encoders have an illuminated white halo around the control knob.
4.12 Function and Temperature Encoders
4.13 ser Interface Harnesses
The temperature and function encoders are linked to the display module via the user interface
harnesses.
The power board is located in the top panel area,
and is held in place by plastic standoff clips. The
power board is connected to the display module via a
harness and controls the following components:
Elements
Door switch
Temperature sensor
Door lock
Lights
Cavity fan
Cooling fan
Vent fan
The power board is a GOEP type board. If being
changed for any reason, the model ID must be
selected for the product it is being fitted to. Refer to
Section 6, Diagnostics, on pg. 34.

4.15 Power Transformer
Input Voltage: 120 VAC 60hz
Output Voltage: 12 VAC
4.16 Thermal Limiter
These products have manually resettable thermal
limiters.
Single ovens have one thermal limiter below the cooling
fan. Limiter is mounted on a bracket with spacers
underneath.
Double ovens have three thermal limiters, one for the
upper cavity and two for the lower cavity in series. On
the lower cavity, one limiter is mounted on a bracket
with spacers below the cooling fan; the other limiter is
mounted on the vent channel.
A thermal limiter will cut off power to the elements/
product, if it senses any malfunction in the cooling
system (see table below). hen a limiter is tripped
“open”, the reset button (orange tab) on the body will
be sticking out and there will be no continuity across its
contacts. The reset button needs to be pushed back to
reset the limiter.
If a limiter is found to be open, the root cause of the
tripping needs to be diagnosed and repaired. Refer to
Section 7.14, Tracing Limiter Faults (pg. 46).
All limiters used on these models are identical.
