Glow worm 45/60 not firing up,pilot lights on new thermostat fitted still won't fire up,thanks

Either the electronics are not recognising that the pilot flame is alight - or the main gas valve is not opening for some reason - the electronics or the valve itself.

If the flame sensor is incorrectly positioned it might not be getting hot enough to trigger the next stage.

I am not qualified to offer this opinion.

Good Luck..., March 2016
