SOURCE: my gas oven flame
the flame failure device( FFD) may have malfunctioned,not allowing full volume of gas through to the burner.This is a safety feature, preventing full gas pressure to the oven straight away.
SOURCE: Oven will not respond
try pressing the oven regulator knob for a while 3 to 5 seconds on ignition its a safty thing so kids cannot gas themselves all cookers have them. you have to hold it in.

Reading the user manual, it states that the flame initially comes on low, until it is "sensed" by the flame sensing device. This to me sounds suspiciously like the flame isn't being sensed and so never gets increased to the normal level.
I've not had time for a proper look at it.... but from a quick glance this morning this looked like a "flame rectifier" probe next to my burner (as we commonly use in boilers to sense if the gas burner is lit). This is just a metal probe. They send a high-ish AC voltage signal (Sine wave) from it, through the flame, to the earthed metal case. The flame acts like a diode (yes it really does work !) and simple electronics detects the change in the applied signal (rectified) due to the flame. I know from personal experience they (the probes) get coated with crud (carbon, etc) and need a good clean. I suggest you try cleaning both it and the metal area opposite it. If necessary the probes metal tip could be GENTLY rubbed with very fine Emmery cloth, etc, if badly coated.
Other than that, if it is sensing the flame, then it must be the gas control device (solenoid valve ?) that is jammed, blocked or just defective.
Simples......

thromo stat bad the tempature knob has a gas valve attached to it along with two gas lines you will have to remove the oven to acess all lines as they run on the backside of the case remove the burners and gas input line copper line remove gas supply tube to all burners remove valve and take to dealer they need the numbers off the vavle for exact repacement not just the numbers off the stove itself east fix with simpl hand tools thermost has a themocouple attached to burner assembly and this is your problem bad part is themocouple is built into thermostat and is no serviceable only fix is to replace "thermostic gas valve"
