went to one of these today and the fan was running and running, pulled burner out and put a bit of card over end and she fired after 10 seconds. Put burner back in boiler and sometimes she fires and sometimes she does not.
Changed the control box and photo cell and it sorted problem.
Question is : has anyone seen this fault before ? and how do you test the photo cell with a multimeter . I can test bigger gas and oil photocells by messring the current because you can get at the wires.
