[Elecraft] K3 push buttons no longer workin

[markmusick at sbcglobal.net]

Mark,
What is the serial number of your K3?
Later K3s above serial number approximately 4000-4100 have a different encoder.
My serial # 3505 had to have the encoders replaced.
The new encoders are apparently more robust. I have not had any trouble with the encoders on K3 serial #7436.
My brother-in-law now has K3 serial #3505 and has not had any problems since their replacement in 2015.

73,
Mark, WB9CIF

In my case the 4 rotary encoders had to be replaced.
