HI i have a cheap Glen (belling) freestanding gas cooker with a single oven/grill. The grill will light ok but only stays on for about one minute then goes out. After this has happened the grill will light again but goes out as soon as hand pressure is taken off the knob. Is this something easy I could fix myself or do I need a gas fitter - the oven only cost 150 quid so don't want to spend much on it
Thanks Matt
