Hey everyone, so my Avalon 921 is showing a status code of 131073 at ECHU instead of the usual 0 0 0 0. It's showing 131073 across the board. I get that it’s related to the hashboard, but could a PMU malfunction be behind this? The voltage readings for the PMUs seem fine. Is it possible that the hashboards are okay and there might be another issue? Everything else in the API log appears to be normal.
Hi, please see my troubleshooting guide for the Avalons.
The link is in my signature space, as are also my other guides.

The guide is also somewhat applicable for 9/10/11/12 series Avalons.
Edit: I remember explaining that same ECHU code for someone, and I found my old post here: https://bitcointalk.org/index.php?topic=5325107.msg57013711#msg57013711
I have one more question, i have some A921 new fans but it is 12V 9A instead of 12V 4.68A. I know that if it is below the factory specs there will be problems for sure. it is right to use them? i mean the new ones 12V 9A?
Should not matter for the most part so long as they are moving the correct amount of air (CMF) or more at the RPM that the miner is expecting.
What model fan did you get to replace the stock ones? And why?
The stock ones that they used, were at least for me and the people I know, just about indestructible vs the ones from other miner manufacturers.

As it is an 9 Amp fan, I would make sure the power wires are thick enough.
Probably you wont have fans at 100 percent pulling the max. current all the time,
but for a while they can be at 100 percent speed.
