  • Pedal Note Stuck

    Hi there,

    The organ at my church has a problem: with any stops drawn a note in the pedal (B) plays. I tried pulling the pedalboard in and out, check both "sides" of the contacts for unusual things but to no avail. Any ideas? I am thinking it might be an electronic problem.

    Thanks!

    Philip

    If the problem persists with the pedal board removed, it is either an electrical issue or a chest problem. If it stops when you pull the pedals away from the console, then it must be a mechanical issue with the pedal itself.

      It continues with the pedal board out.

    Not sure of the configuration of your instrument, but it could also be a stuck contact in the relay or switch stack.

      It would be useful to have more information about the organ. Are the chests Pitman chests in which case it could be a stuck primary valve in the chamber. What kind of switching system does it have? Has it been updated to solid state, then who is the manufacturer? Either by using a meter or a small 12 V test light, test the pedal contact to see if it is shorted or stuck. It could be so many things. Time to start troubleshooting.

        That's the problem... I know minimal details of the organ.

      I guess you would say the B is ciphering. Is it just one pipe that ciphers, or is it any B pipe? I sounds like it is any pipe, in which case if it's a tracker/mechanical action, the pallet valve might be stuck open, either because of mechanical interference, or because the spring is weak and needs to be replaced. For electropneumatic or direct electric, it could be the solenoid driven valve stuck open, either because of the solenoid, or a problem with the electrical system as mentioned.

        Just one B note (on any stop).

        Is this low B or high B? It matters because as I understand it Moller used pitman chests in which case the lower pedal octave pipes will be on their own offset chests. So low B would indicate an electrical switching problem. High B might well be a sticking primary valve problem. I'm no expert but a look in the chamber to see if these pipes that are sounding are all on the same chest or not.

        The B below the second C of a 32 note pedalboard.

      Well it seems the problem has gone away for now but who knows if it will act up again.

        Though it might be a harbinger of things to come.

        Probably the pallet valve I would think then. May very well need to be releathered.
