[Elecraft] K3: VFO Freeze - board reseating/DeOxit not solving problem

[John K3TN]

My nearly 2 year old K3 had the VFO A freeze problem early on and I sent it
back to Elecraft. The jostling during shipping apparently temporarily cured
- they didn't see the problem, tried temperature cycling to eliminate other
possibilities and sent it back. 

The problem recurred, so I did the board reseating and that seem to fix it
for a while. Then it came back, tried spraying contacts with DeOxIt, problem
return again and now doesn't seem to want to go away.

Is there any possible culprit other than dodgy board seating? I'm sort of
starting to feel maybe it is more something with the VFO A knob/encoder, not
the board connections.
