Thanks man, it is not related to the temperature at all. The second I start it up in a cold dry enviorment, I get first error 351, then within 2 minutes I have all 3 error codes
Then download Whatsminer Tool and flash the latest firmware, there is a good chance that it will fix these false temp positives you are getting, you can also join Whatsminer Telegram group here >
https://t.me/WhatsMiner, there is more related content and more folks who are experienced with MicroBT gears than we have in the forum since Whatminer isn't really as popular as Bitmain.
