This is my son's set. It was given to him about six months ago by
someone who didn't know what the four links most likely meant. I
removed the fan, disassembled it, cleaned the shaft and bushing with
isopropyl and relubricated it with a small amount of ATF,
(transmission oil). It has been fine until recently when it started
sporadically shutting down again with a four blink code. So I'm going
to investigate it again. I know that I can purchase a new fan, however
I just thought that maybe a different lubricant, one that doesn't get
sticky when subjected to high temperature is what I need. Has anyone
done this successfully? Thanks, Lenny
