, push in and turn the control knob to the full on position (large flame symbol). If your hob has an ignition switch on the facia, press it in until your burner lights. • Hold the control knob in for 15 seconds then release. If the burner fails to light within this time, release the control knob and wait one minute before attempting to re-ignite.

Push in the control knob and after a couple of seconds press the ignition switch. • Hold the control knob in for 15 seconds then turn to desired heat, If the burner fails to light within this time, release the control knob and wait one minute before attempting to re-ignite.

I have exactly the same problem and am trawling the internet to try and solve it. My oven is gas and I've had a qualified gas engineer who is a friend look at it - he tells us we need a new safety cut out device which is basically a long wire - but i cant find it.
Have you had any luck????

First, Change your technician.
There is a part that senses the heat from the ignited gas, usually quite close to the flame on the oven burner where it first ignites. It is called a generator and it produces about 1/3 of a volt, that holds the gas valve open only while the flame is lit, as a safety device. Pressing the knob at the time of ignition bypasses this by holding the valve open, after releasing the knob then the system relies on the presence of an oven flame to hold the valve open. Check the generator at the point it enters the oven control valve, is it loose? Maybe it is faulty or the oven valve is faulty. Any real technician can identify the the problem easily.

indicates the oven door is not closing properly
get a technician out to check and adjust the hinges

I had the same problem. I solved it by re-attaching a device which had come undone. On the right hand side of the burner is a rod with a metal wire attached. This was lying loose. It should be fixed to a little grey clip which is itself attached to a a piece of metal. By re-fixing the clip and the rod to the clip it solved the problem. Hope this helps. I have photos of how it should look. email [email protected] for a JPG.

I'll give this a go! With a cooker like this, you depress and then turn the control knob, press the ignition button and continue to depress the control knob for a few seconds. This is because a device called a thermocouple is heated by the flame and you have to continue to depress the control knob so that sufficient gas flows to heat up the thermocouple. If the thermocouple does not get hot or stay hot then the gas valve is automatically closed - stopping the gas. The thermocouple is a 'flame failure' safety device. If the gas gets cut off then the flame goes out and the thermocouple goes cold switching off the gas valve automatically. However, you are having to try and manually keep the gas going for a good five minutes. I would think that there is either a problem with the thermocouple or the gas control valve!

The knob won't have any effect on the flame size.  The knob controls temperature.  If you're referring to the pilot light staying on and then the main flame not going on...that's another problem.  If the main flame will not go on, the assembly that controls the main flame is likely defective.  If the unit has a thermocouple, you might change it out first.  Sometimes, that's all that is needed and they're cheap.

make sure clock is set properly - refer to your instruction book. to test if clock is in fact faulty, access the clock and bypass it by shorting together the two wires to the clock relay
