Rangemaster toleda ovens not working?

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......

Depends on how old it is, most of the older ones require both hotplates removing.

SOURCE: Both ovens only light to pilot light, wont go

Faulty FFD's ( flame failure devices) once the flame is established it allows the full flow of gas to the burner... must be a gas-safe engineer to replace part..

SOURCE: i have a leisure rangemaster 110 double gas oven

the flame safety device need replacing (FFD)... this lets the full gas through when flame is sensed... safety 1st as a gas engineer will be required..
