Location of thermal fuse in leisure cookmaster range cooker

The light may just be a burned out light bulb. Remove it and take it to an appliance store to find a replacement. As far as the oven goes, elements do burn out. They are relatively inexpensive. Make sure you have turned the oven OFF before you do anything. The heating elements do pull out and you can replace them yourself. Take the information about your oven and the heating element to an appliance store for a direct replacement.

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.

where the power goes in there should be fuse links on both sides if they all in then its the thermal fuse inside

I have a Flevel 100 and wish I had checked out all the problems everyone is having first as I would never have bought it...what a waste of money...already replaced the element on it...the ordinary cooker died weeks ago...now the fan one has died leaving me with no means of cooking in an oven...this is going to the nearest dump as soon as I can get to the shop to buy a very cheap standin...Flavel I hope you are ashamed!

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.
