Avionics Reluctance King KY 92
Posted: Thu Oct 19, 2017 9:11 am
New install KY 92 comm(720 chl) over a decade ago.
One knob feels slightly sticky. Radio has seen very little use.
I asked avionics guy to lube the mechanical rotating switch part.
Purchased new with understanding contact surfaces were GOLD plated. Longevity.
The Independent technician is a survivor of original shop that I had purchase/install.
I sensed a little fear in his response. Well maybe I should say strong reluctance.
One statement was " If I spray contact fluid on the switch the fluid will cause the plastic portion of the switch to deteriorate." Very surprised by that statement.
Is it safe to forcibly turn the one sticky knob?
What is really going on in servicing aged avionics?
Please advise.
