Hi,
I've just cleaned the right side of the Antminer S3+ (as if you was looking at it with the Ethernet port at the back) by blowing to get the dust out. I took off the metal heatsink and cleaned up the paste a little and reapplied some of my own (not too much at all). I made sure that none was overflowing onto the other components and then reapplied the heatsink and then turned on the miner. Throughout this process I was grounding myself by touching my PSU's metal casing, before, during and after this.
When it was on, I noticed my ASIC status showing ------- in the bottom left. I noticed a small RED LED illuminated (RF1) on the miner on the opposite side from where I was working on (the left side) as you can see In the photos below. I've tried restarting the miner, but still the same issue. I never had this issue before.



Any ideas?
Thanks,
Owen.
