one of the hobs is stuck.spring action is lost and the turnig 'axel' (on to which the knob fits) is really stuck.I wanted to loosen the nut and see but i was worried as I did not know where the gas input was, in case I needed to stop it.

Hi Foxy, many thanks. I returned to this site many times during the first couple of days and as there was no response I did not rerturn till today when I did accidentally.
I sprayed a bit of WD 40 let it stand for 5 mts and the shaft got loosened. Then I cleaned the area thoroughly and just lubricated the shaft with a drop of singer oil.
Started working beautifully.Advised my wife to keep this area nice and tidy. Almost 3 years on thing are excellent. Even my wife was pressurising me to call someone and get the whole control system replaced which I resisted knowing that the damage on my purse would be significant.
Many thanks any way

Hi Muta, if you turn the shaft,you can create a leak so please do not.The engineer will have to be called who is CORGI registered and replace the gas tap assy.All the best.
