Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Please tell me, what make and model of organ you are asking about ?
Use the Reply To Expert function, to let me know.
Thanks for the information.
I don't think there is any way to factory reset a Baldwin organ, though I have not looked up specifics for this model yet. (I will do so, now.)
If the stops were pistons, then you'd hold them, and set them to the desired value, then release them.
Look for three pistons ... and let me know what stops are coming On, if you can identify them.
If the stops are Great, Swell, and Pedal, then that's a complete spread, typical of a circuitry defect or defects. I suspect your Baldwin will require electronic (or mechanical) repair.
Since other Experts may have a more detailed or more favorable opinion, I have Opted Out, opening the case to other Experts in this category.
