I have a Rangemaster 110 gas cooker. Everything works perfectly on it apart from the right hand oven i.e. the large non timed oven with the draw underneath. The gas lights ok with no problem, but it doesn't matter where you turn the control knob to, the flame remains small and the heat doesn't get above a 'keeping warm level'. I don't think the jets are blocked because the gas lights straight away and are lit all the way across the burner. It looks like there is some sort of thermostat or temperature sensor that lies across the left hand side of the flame. Could this be gone? Or is it likely to be something else?
Its going to be the fsd gone if the burner lights all the way across, the type of control sparky is on about hasnt been used on domestic uk cookers for around 30-40 years., as its a gas passing part, unless you are gas competent you will have to call in a pro.
Will the flame go out if you turn the control knob to the off position?
Sometimes gas cooking control knobs have two seperate types of control in the one knob. One control turn the gas on or off, one adjusts the variable quantity of gas allowed through a gap to your flame jets. Some control knobs can get gummed up and stick a little. The can be fixed by carefully taking apart the control knob, taking note of EXACTLY how everything goes back together and cleaning any gummed up bits. Then reassemble the knob and drizzle soapy water over the control to test for leaks. A leaky gas join blows bubbles and makes noise. Let me know if this fixes the problem.

I have the same problem, I use a plumbers blow torch and heat the flame sensor up (keep the control knob on position 9) after a few seconds the full flame comes on.
Been doing for the last few years.
