Your gas oven is fitted with an electronic controller which manages the operation of the burner
and monitors the flame. This controller includes features which ensure the safe operation of your
appliance and will prevent the build up of unburnt gas, should a fault occur.
It is normal for the flame to turn on and off during cooking, to maintain a stable temperature in
the oven. The Thermostat Indicator Light indicates when the flame is on or igniting (indicator
glows), or when the flame is off (indicator off).
The burner flame can be seen by viewing through the 2 holes in the front of the burner cover.
Ignition and Response to Ignition Failure
The controller will attempt to ignite the flame when an oven function is selected and the
Thermostat turns on (indicator light changes from off to on). The controller will make up to 2
attempts to ignite the flame, stopping if a flame is detected by the controller. If by the end of the
2 attempts a flame is not detected then the burner and ignition will be turned off and a delay of
90 seconds will be observed. During this delay the controller will not respond to the Function and
Thermostat controls.
At the end of this delay, switch the Thermostat or Function Selector off and leave off for at least
5 seconds. Then switch the Thermostat and Function Selector on again to re-attempt ignition.
If the oven controls are left on when the delay ends then ignition will not be attempted until the
Thermostat or Function Selector is first turned off for 5 seconds.
Response to Flame Failure
If the controller cannot detect flame due to a fault, then the controller will respond
• firstly by attempting to re-light the burner with a sequence of up to 3 attempts and
• If the re-lighting sequence is not successful the burner will be shut off.
The re-lighting sequence will include up to 3 attempts to re-light the burner, stopping if a flame
is detected by the controller. If by the end of the re-lighting sequence a flame is not detected then
the burner and ignition will be turned off and a delay of 90 seconds will be observed. During this
delay the controller will not respond to the Function and Thermostat controls.
At the end of this delay, switch the Thermostat or Function Selector off and leave it off for at least
5 seconds. Then switch the thermostat and Function Selector on again to re-attempt ignition.
If the oven controls are left on when the delay ends then ignition will not be attempted until the
Thermostat or Function Selector is first turned off for 5 seconds.
Recognising a Safety Shut-down Condition
During normal cooking the Thermostat indicator light is on when the burner flame is igniting or
on, and the Thermostat indicator light is off when the flame is off.
If an oven function is selected and the Thermostat light is on, but the flame is not on or
attempting to ignite then the controller has invoked a safety shutdown of the burner. A 90 second
delay is observed from the time the shut-down occurred before the controller will respond to the
oven controls.
Once the delay period has ended the Thermostat or Function Selector must be turned off for at
least 5 seconds before oven functions can resume.
Power Failure
In the event of an interruption to mains power, the restoration of power will not cause the burner
to ignite if the controls were left on. However the grill element will resume heating on models
which do not have an electronic clock.
To resume operation of the appliance after a power interruption:
• First turn the Function Selector or Thermostat controls to the off position. The controls must
remain in this position for at least 5 seconds
• If the appliance has an electronic clock then set the time of day on the electronic clock.
Normal operation of the appliance may now resume.
