On my last flight of the day Wednesday I had a trim failure alarm on my KFC150 autopilot. The autopilot had always worked fine before that. The trim light just blinks during the self test and when I push the test switch all the lights illuminate and then the command bars fall out of view and the trim light constantly blinks again. The electric trim still works. I recycled the breaker Wednesday and flew a number of legs today so it has been electrically recycled a number of times now with no improvement. My manual trim wheel seems stiffer than I recall but I rarely use it since I have electric trim, which works fine. My avionics guy can't get to it for while. Is there somewhere I can lube and see if the manual trim gets easier and maybe the autopilot will work again if something is just binding or dry. If so, I assume removing the belly panel (one piece belly) and looking up in there, something may be obvious ? Thoughts ?
