sustain pedal doesn't work

by Steve
(Simi Valley, CA)

Sustain doesn't seem to work. I plug in the pedal and it won't sustain. I unplug it and plug it back in and it won't stop sustaining. The pedal doesn't respond. I've tried both ways, with the pedal sustaining while pressed and not pressed (switch on the bottom) but it doesn't seem to make any difference. I've tried other pedals and they do the same thing. I've tried turning half damper on and off to no avail. Also, a reset to factory defaults does nothing as well.

If you plug the Sustain Pedal in while the piano is turn "ON" it will not do anything. Must turn the piano/keyboard "OFF" THEN plug in the pedal then turn on the keyboard. Then it should sustain properly

I can't use my sustain pedal Yamaha NP-12 Piaggero
by: Anonymous

I had the same problem. My sustain pedal just stopped working. As someone else commented, the sustain pedal is a simple on/off switch. I checked my pedal with an ohm meter and there was no continuity with the pedal pressed or not pressed.

So it was not a polarity problem - it was a defective pedal! These pedals are very cheaply made and I suspect they have a high rate of defective pedals. My pedal is still under warranty so I am returning it.

I can't use my pedal too Yamaha Np-31 Piaggero
by: HELP

I have a Yamaha Np-31 Piaggero and my sustain doesn't work too. I was just playing, using the pedal, then stopped using the pedal for a second and the piano was having sustained notes without de pedal being used. So I turned it off and I turned it on and now the sustain doesn't work with pedal or no pedal. Please help I'm so annoyed, I use the pedal most of the time, and I get triggered everytime I try to play without sustain, is uncofortable. Help!!!

Fix Sustain Pedal function
by: Anonymous

The sustain pedal is a simple on/off switch. Test function with an ohmmeter. Touch both parts of the jack on either side of the black insulator ring when not touching the pedal and there should be continuity of the circuit. Depress the pedal and it will no longer conduct. If this is so there is nothing wrong with the pedal.
Go to piano function button and press it. Scroll through functions with >> button until you get to "Assignable Pedal". Turn round selector knob until the word "sustain" appears then press execute button and sustain pedal your sustain pedal will now work!

Peddle won't work
by: Anonymous

I have the yamaha p 45 and I bought it with a spoon sustain peddle and a stand. I used the peddle for a few days and it worked perfectly fine. One day I was just playing a new song I learned for my mom and then I stopped playing. A few hours later I went to play again but the peddle just didnd't seem to work. I tried pulling it put and plugging it back in, I tried turning the piano on and off but nothing seems to work. Does this mean its just broken?

my pedal does not have a switch ANYWHERE! Yes, I checked the bottom, I checked the side, though there isn't a space to put it. Heck, I checked to inside and there's NOTHING WHATSOEVER! It won't work. Before I turned it upside down and it worked, but now I guess the magic power wore out and I don't know what to do.

HOW AM I SUPPOSED TO PLAY MUST GET OUT NY MAROON 5 IF I CAN'T SUSTAIN!?!?!
im triggered

My sustain pedal stopped working so after some switching on and off and turning the switch at the bottom of the pedal, I gave up and bought another one. Now I have 2 pedals that don't work?! Any ideas?

DGX-640 Sustain is WEAK!
by: Larry S.

I've had the YPG 625 and 635. Both instruments have perfectly fine pedal sustain. My DGX has extremely minimal sustain... its ridiculous actually. I've been thru every possible setting/adjustment and been thru the manual. I've tried THREE different pedals that all work fine with 2 different YPG-625's and a 635! It's difficult to believe the piano itself is faulty. ANY IDEAS???

sustain pedal working in reverse
by: Dom E

I have a Yamaha MO8.
I had this issue and the turn off , unplug pedal ,wait a minute or 2 , plug pedal in and turn on keyboard did not work.
What did work was turn off, unplug pedal, wait,plug pedal back in but keep pedal depressed while turning on the keyboard. Good luck.

How do you switch the polarity inside the pedal when there is no switch?

sustain pedal
by: Anonymous

Actually, the pedal has a switch on the bottom that allows you to change the polarity. I ended up taking it to a repair shop and a new pedal worked! The two pedals I tried were both broken. Turns out the pedals are very fragile and the wires in the cord can get disconnected. A new pedal did the trick. I have a S90ES. I guess the keyboard is perfectly fine, it's the pedal that was the culprit. For me, it was coincidental, I suppose, that both pedals I tried were faulty.

You don't say which keyboard you have, but some of them work on reverse mode. In other words you have to go into the utility set up and reverse the polarity of the sustain pedal. I had to do that with my previous yamaha keyboard.

Tyr plugging in the sustain pedal with the power off. Never plug it in with the power on.
