I believe the main oven's thermostat has failed. The oven ignites but the flame never gets above the lowest setting, even when the knob is turned right up to mark 9. Is this likely to be the termostat and is this the unit at the back of the oven right by the flame? It seem to be just screwed in?

its more likely to be the (fsd) fail safty device when the oven is turned on the flame will be low after 60 seconds the fsd will open and the flame will rise check inside the oven across the flame there should be a bulb shape stat if this is not across the flame the fsd wont open the fsd should be changed by a engineer hope this helps
