Thanks for that.
I am assuming that the smell is only detected from the outside !!
OK, sometimes when the flue is cleaned, there is dust and soot that has become loose, but not completely removed.
It willl then take several hours or days for this to be burnt off by the small amount of heat produced by the gas burner. This could be the issue here.
Failing that, the other problem that can occur is the jet itself.
Over time the hole gets corroded and this can not be cleaned. The jst has to be replaced. The problem is that if the hole is corroded, not enough gas is let through and his can result in poor burning of the gas. If you notice the fridge is not as cool as it was, you should change the jet
