The Cad cell has no effect on it lighting.

Might want to pull the nozzle assembly again, and see what it looks like.

Its not the cad cell.

When is the last time the burner set up was checked? Over fire draft, smoke, CO2, stack temp.

Reclean the nozzle assembly. And install a new nozzle again.

Nozzles are not something that is reliable.

With a 500 or so dollar Bacharach Fyrite test kit.

My setup for checking burners is a fair bit more yet.
