Re: Rangemaster gas grill - little or no gas pressure
Have just had a brand new Rangemaster 110 installed for less than a week. Initially everything worked fine, then, Christmas day the gas stopped working completley on all hobs. All cylinders were full but no hobs would produce gas when knobs tured.
I have tried the rangemater help lines but they are helpfully off until the 29th.
Not impressed as there appears to be no obvious answer, can anyone hel;p?

common problem, there is a device in the oven called a solenoid/ff device these are safety devices and fail after a few years. replacements can be obtained from main stockist Gas On spares on 0121-585-7799
Do not use as yellow flames indicate incomplete combustion and where gas is involved carbon monoxide and its associated dangers.. please do not use and get a gas certified engineer to either repair or replace due to the age of the appliance.. Thanks
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.
to find out if the regulator is good or bad, turn any of the burners that do not have the problem, one at a time but take a close look at the flame and see if the flame goes lower and lower as you turn a second burner and a third and the fourth one, if the flame goes lower and lower the regulator is bad. but if the problem is with just the grill one , it has to much air, you can turned down the air where the burner meets the valve that supplies gas to it the burner has a vent, it needs to be close a little bit, you can close it little by little and testing the burner on the on position until the splutter goes away.
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.
