Hi, the sustain pedal on my Kawai CN41 digital piano doesn't work.
While moving the piano, the pedal wire that clips into the underside of the keyboard was inadvertently jerked out. The edge of the plastic clip is broke and now the sustain pedal doesn't work.
I think I have a connection problem where the clip gets plugged into the underside of the piano keys? Are there replacement parts or suggestions?
Here are videos on How to Fix the Sustain Pedal on a Piano:
In some cases, when the keyboard is switched on, it sustains by itself, even when the damper pedal is not depressed. In this case, try doing either a factory reset or when you switch on the piano, make sure you keep the pedal pressed. It should reverse the action.
With digital pianos, usually the pedal is either not registered or is registered in reverse if the power is on when you plug in the pedal. So you just need to turn-off your digital piano keyboard, plug in the pedal to the sustain jack and then switch-on the power. This solves the problem most of the time.
If you're playing the piano after a very long gap, the Damper, Sustain, and Soft pedals may not work. Occasionally it works, but the very next moment it doesn't work for the same keys. If you have moved recently, something may have been jarred during the move process, which may break something related to the pedal. And most don't understand the internal wiring to fix it by themselves.
In some cases, a wire from the pedal gets 'unplugged' or broken. The problem with the pedal sometimes is that the wire at the back is not put in a right place.
In some cases, even after opening the pedals box, you may not notice anything wrong. Opening the cover of the piano to check connectors or if anything else looked wrong, but it may all seem very clean and nothing seemed to be unplugged. In that case, you may need professional help.
With sustain pedals on digital pianos, there are a couple of places where things could go wrong. The first is the physical connection itself. May be while moving the piano, connection between the pedals and the cable / cable stops would have become loose. These fixes are easy to diagnose and to fix. It could mean tightening up some screws, or if the cable is broken then probably replacing it. If the main board itself is not recognizing the Pedal presses then it becomes a bit tricky, since you have to trace if the signal for the "Pedal Press" is reaching the circuit board.
When trying to reset the program (to make it go back to normal) make sure to save all your file so you have a copy, again if it does not work you need to consult a technician or service centre because sometimes we need to check the inside of the unit to make sure or wire and contact is place. To do a reset you will need a service manual of your Digital Piano.
