Antminer L3+ pcb problem temperature


yesterday i received my L3+ and this morning i had a problem with it, one PCB is not showing Mh/S and no temperature pcb and chip, as seen on the picture i uploaded. and in the kernel it say “temp data failed” asic status only 0

let me know what to do
thanks a lot


I dont have an L3 but you can try replacing the fan…if it is a 3 wire red, black and yellow color fan that is…if the tac on the fan is not putting out a reading then the board thinks the temp cant be controlled and shuts down the miner…a few of my miners work in this manner…


thanks i will try this :slight_smile:


if this is the issue…go with a high rpm fan…2000 rpm or higher…but just make sure you get a PWM fan…

mainly just make sure you get the same wire colors that come on it…if it comes with blue and no yellow and the old one has yellow black and red then it wont work…

any 4 wire fan works fine for 3 pin connectors that have a yellow wire on the 3rd pin…in my experience and trial of learning about fans after buying the wrong one 3 different times…
