My leisure classic 110 gas cooker will not increase the flame in the ovens when turning the dials (just stays very low)

This question also edited for clarity. 'make model (what it is)' first. Proper names with capital letters too. :>D

It needs a new thermostat. this has to be done by a registered gas technician, so call for service.

Where can I purchase an Xenon II Instructions book?

Several things to check. First be sure the pilot light flame is directly striking the thermocouple. It is a pencil sized rod that is next to the pilot light. Sometimes people reduce the size of the pilot flame to save gas. You may need to increase the pilot flame. Follow the small gas line from the pilot flame back to the gas valve. There is a screw where the small pilot gas line goes into the valve. Remove the screw and then deep in the hole is a tiny screw that can only be reached by a tiny flat blade screw driver. Turn the screw counter clockwise to increase the pilot flame. The thermocouple needs to be red hot to work properly. The second item to check is to see if there are any breezes that occasionally blow through the kitchen. Sometimes the hood fan will draw air under the ovens and actually blow the pilot flame out. Same fix, increase the flame. You may also experience low gas pressure to the appliance during heavy usage. You would need a manometer gauge to check for proper gas pressure. In short, if the oven goes out during your busiest time when everything gas powered is on, the oven may be starved for gas.

I had a similar problem when my new Leisure cooker was installed last December. The burners would light when I held the knobs in but when I let go the flame would go out. The engineer took off each of the burner knobs and stuck a small wad of aluminium foil between the inside of the knob and the contact on the front of the cooker - he said it's a design fault and the gap is just a bit too large for contact to be made reliably. This fixed the problem and I've had no trouble since.

sounds like the ffd is at fault, this is a safety device that alows the main flow of gas through. when the cooker is cleaned the sensor can be moved by accident from its position over the flame, another reason could be a build up of grease etc, stopping the flame reaching the sensor. if none of these then the ffd unit needs to be replaced. they are about £20.00 for the part

you should not attempt to repair this unless you are gas registered. It is against the law!

bloody hell that is so scarey i have the same problem and its round about the same time yours went funny if you have a solution can you let me know as im looking for the answer myself [email protected]

I just installed one in my house. I found that when you start the lower (gas) oven you need to turn the dial all the way on to 500*, push the knob in (you should hear the igniters clicking), then even when you see flames coming out of the burner, continue the ignition for 10 to 15 seconds. It should continue to stay lit thereafter.

It sounds exactly the same as I am experiencing on my oven of the same model. My theory is that the full flame gas is controlled by a thermostat, and that this has broken hence why the oven only stays on preheat. This will be a matter of a replacement part. Most likely the thermostat is a bi-metal strip that, because it has heated and cooled so many times in it's life it has simply finally given up. Try searching online for the correct part and get a corgi registered fitter or another suitably qualified fitter to come and replace it.
