The number 1 button always sticks. Have to always use the main phone which is not a cordless to dial. Have 2 cordless phones with the main phone not being cordless. Both cordless have buttons that stick.
Tish, Most likely this is just dirty button contacts. You would need to be a bit handy to take the phone and circuit board out. But if you can do that part, basically it's just a matter of cleaning the underside of the button contact and the circuit board that the button touches with alcohol and a q-tip.
