Hey everyone, We have had a couple of good years out of the sovereign BBQ, but of late the flame seems to go out a few times before staying alight, sometimes not! It takes a few relighting efforts for the thing to stay alight, gas bottles are full, no problems in the van with the stove and the water system works fine. I don't think it is the gas system as such. I have checked the pyro sensor that runs the auto shutoff and it is positioned correctly according to the sovereign website. Can these fail or become worn out???? Anyone had any similar experiences and can offer a solution??? Thanks guys and gals....... Pete and Tracey.
