Sticking keys

[John Ross]

The fact that it only happens when the damper pedal is used, suggests higher friction for those notes. When the damper pedal is used, the damper spring 'assistance' is removed.
So it could be the keys need eased, or an action centre is tight, and needs to be replaced, or lubricated.
If the notes are next to each other, be sure and check nothing is between the keys.

  I have a customer that has a Yamaha console. Two or three notes stick only when the damper pedal is used. I have checked the damper lever felt for indentions and there OK. Briddle strap wire is clear. Key dip is the same as other keys.  I checked a few other things that another Tech suggested but nothing seems to stop the sticking. Any ideas will be appreciated.
