Whatsminer M2 - Temperature sensor error

[rohith_r]

Hi,

I brought a Whatsminer M2 five months back. Since last week it is not hashing.
PSU is working fine.


It says in

Whatsminer Dashboard

Event cause  - Slot 0 Temp sensor error
Event Action - Reset hash board

https://drive.google.com/open?id=1k8kBVa1lbAZgp16qWPoG4Qn-I0jT4gas

In system log

Slot 0: Sensor invalid, reset hash board

Could anyone pls let me know how to reset the hash board or factory reset the miner ?
any help is much appreciated.

Thank you,
Rohith

Check data cable and power cable connections.

Try soft reset in the software.

Try hard reset by using the reset button in the miner front panel.

Yeah, I unplugged and plugged again all the cables in the miner.

I tried both software reboot in miner webpage and reset using reset button on miner.

But I found it just resets the pool settings and not the whole miner (since it didn't change miner login username & password)

Any procedure to do full miner reset ?  or any further suggestion ?


Tried the troubleshooting guide https://drive.google.com/file/d/1hwa17Skw1DFBDoHDDmgJrlaqrScvuvRX/view?usp=sharing from Whatsminer. Page 2 / 5
Though the guide is for M3, it looked same for M2

Thank you,

If any of those tips shown in that 'Help Desk Document.pdf' doesn't work, I would contact Pangolinminer for more specific troubleshooting.

Did you manage to resolve this issue? I'm getting the same error

I've had the same problem and cleared it by taking the miner apart and blowing the dust out.  I was  a chunk of fuzz causing the read error.   I'll be listing an M2 on eBay w/o PSU soon.  Prob go cheap.
