    If the unit is more than 10 years old, I replace the rollout switch and both the primary and secondary safety switches as well.

    All you need is a wire brush and some nitro to clean it. Takes longer to pull it out then it dose to clean.

    I think I have recycled 25 lbs of aluminum from those gas valves alone.

    If they want it to work now, I would rebuild it. Anything less and you could get dinged by return visits. And those rollouts are notorious!

    Blue box of death. Those ignition controls suck.

    Question:

    How can you tell if a JCI ignition module is bad...?

    I typically use the same approach as Timebuilder.

    In fact I think its a universal standard procedure for those that have worked on York units with any frequency.

    However, the oriface I typically keep, they dont go bad.

    Also, how on earth do you know the gas to the pilot is adequate?

    Never said gas to the pilot is adequate, gas on pilot outlet ov the valve has good pressure. Checked with manometer.

    Thats what I was getting at, pressure does not equal volume.

    Went back, took apart burner assembly, replaced part of pilot tube, cleaned orifice and holes on crossover tube. For some reason couldn’t get old orifice out. It’s running. I also replaced spark rod and flame sensor. Don’t want to go back for stupid calls. Thanks for all inputs.

    That's good.

    The orifice is held in by a crimp on the crossover tube into a groove in the circumference of the orifice.

    Get that Lisle tool for future tests. It can be impossible to hear a spark on a windy roof, and it takes place on the other side of that metal wall. If you have the tool, you can easily confirm a spark.
