Cooktop ignition or cooktop burners faulty

Is the power on?
Are the sparker (ignition electrode) or burner holes

blocked by debris?
Are the burner heads correctly located? See the section

entitled ‘Cleaning’.
Remember that each cooktop burner has a special

safety device that stops the flow of gas if the flame goes

out. When lighting a cooktop burner the safety device

has to be overridden by holding in the control knob so

that the gas can flow. This allows the flame sensor to

heat up and operate the safety device. Keep holding the

knob pressed in to let the gas through to the burner for

few seconds. The igniter should spark and light the gas.
If, when you let go of the control knob, the burner goes

out, the safety device has not held in. Turn the control to

the off position and wait one minute, then try again this

time holding in the control knob for slightly longer.

Cooktop burners will not light

If only one or all the cooktop burners will not light,

make sure that the parts have been replaced correctly

after wiping or removing for cleaning.
Check that there is not a problem with your gas

supply. You can do this by making sure that other gas

appliances you may have are working.
Do the burners spark when you push in the control

knob? If not check the power is on.

Steam is coming from the oven

When cooking foods with a high water content (e.g.

oven fries) there may be some steam visible at the rear

grille. Take care when opening the oven door, as there

may be a momentary puff of steam when the oven

door is opened. Stand well back and allow any steam to

disperse.

An oven fan is noisy

The sound of the oven fan may change as the oven

heats up – this is perfectly normal.

What cleaning materials are recommended for the range?

See the ‘Cleaning’ section for a full list of recommended

cleaning materials.

We do not recommend corrosive or caustic cleaners

as these may damage your range.

The knobs get hot when I use the oven, can I avoid this?

Yes, this is caused by heat rising from the oven, and

heating them up. Do not leave the oven door open.

6. Troubleshooting

If there is an installation problem and I don’t get my

original installer to come back to fix it who pays?

You do. Service organizations will charge for their

service if they are correcting work carried out by your

original installer. It is in your interest to track down your

original installer.

Food is cooking too slowly, too quickly, or burning

Cooking times may differ from your previous

oven. Check that you are using the recommended

temperatures and rack positions. See the oven cooking

guide section of the instructions. The oven control

settings and cooking times are intended to be used

only as a guide. Individual tastes may require the

temperature to be altered either way, to get the results

you want. Try cooking at a higher temperature setting.

The oven is not cooking evenly

If you are cooking a large item, be prepared to turn it

round during cooking.
If two racks are used, check that space has been left for

the heat to circulate. When a baking sheet is put into the

oven, make sure it is placed centrally on the rack.
Check that the door seal is not damaged.
A dish of water when placed on the rack should be the

same depth all over. (For example, if it is deeper at the

back, then the back of the range should be raised up or

the front lowered.)
If the range is not level arrange for your supplier to level

it for you.

Oven not coming on

Is the power on?
If not there may be something wrong with the power

supply. Is the range supply on at the circuit breaker?
If using the multi-function oven, have you set a cooking

function?

Oven temperature getting hotter as the range gets older

If turning the knob down has not worked or only

worked for a short time then you may need a new

thermostat. This should be installed by a service

technician (see the ‘Service and Parts’ section of the

instructions).
