Ja having more than 1 miner to use for testing/spares is nice but largely only useful for the Avalons as their actual hash boards are highly modular. Ants', ones from Inno and MicroBt and others not so much. The hash boards are large 1-piece boards and those manufacturers generally require sending them the entire miner for repairs. Canaan will try to let you troubleshoot it and then send you the parts.

Shipping international is a bit of a PITA on top of it all.
I'm going to stick with L3's for now, hopefully L7's next year. Bitmain has a repair shop in the USA now, which seems like should make dealing with issues like this easier.

Reseller offered to refund my purchase or have unit returned to china for repairs.
I am sending it back for a refund.
Something I have learned through this is the importance of having more than 1 unit of any particular make/model.
Having the ability to swap parts is critical.
Looking like I might just buy more L3's instead.

For anyone following, or who finds this in the future I am going to share my experience.
Canaan just got back to me, asked if I had another unit to swap control boards.
This is my first unit of this make and model so I do not. I told them this and about the RED led on the power supply.
Waiting for response.....

From what has been written here in the Forum it is always a PSU problem. After replacement of the PSU the miners (Avalons, ones from Inno or BtMicro, or Bitmain, etc.) have always worked telling us the controller side is fine.
Quite an experience getting into this whole mining thing! No shortage of obstacles to overcome, lol. I would not have had the patience for this in my 20's..... Thanks for the help! Hopefully Canaan will help me out, otherwise it gets returned and I buy something else  |

Seems odd the PSU would be powering the controller but not the hashboards.
The high power section supplying power to the ASIC chips is controlled separately with a variable voltage output set by the controller. Bitmain machines often have problems with the PSU high-power section while the miners still work enough to report problems via the GUI. is that typically an issue with the controller or are there components in the PSUs that are known to fail? |

On a positive note, I called the number listed for that reseller and left a voicemail earlier and the guy just got back to me.
He wants me to contact canaan and see what they think first and if I don't get it sorted out by Friday he will accept the return. Good news.
I am inclined to believe it is the power supply. The PSU has an LED indicator on it, which flashes green during startup and then goes RED. I don't recall seeing it red before now.

Ya might want to let us know who the reseller is. Was it Blokforge? They are one of the very few factory-authorized resellers of Canaan gear and I know that along with their website they also have Amazon pages. If it is Blokforge you used they should be very responsive to your problem as they are an excellent company to work with. "NewMarketBrands" Return address is in Canada, unit was shipped from HongKong. I assume its someone who just bought from someone in China and had it sent to me. Amazon approved the return, so I guess now the question is do I believe they will actually give my money back if I send this thing to the address listed. |

With your log showing Vo[0] PS[16 1197 4 0 0 1252] I'm thinking that there is a problem with the PSU or a string Vcore regulator. Mine show values for all spots with no '0's. I take it you have contacted Canaan or your reseller about this? If not you should. I emailed Canaan. I purchased through Amazon, working on contacting the seller to process a return. I have low confidence in the return process but maybe Amazon will help if there is an issue. |

Miner has been running for 6 days, it quit hashing a few hours ago and reboot will not resolve.
In the overview menu, mining status is red, network status red, fans status all green, temp status 31c(T) GREEN, 0c(H0) 0c(H1) 0c(H2) all RED.
Canaan garbage?
It's sitting next to 16 Antminer L3's which run just fine.
Anyone have any suggestions?
I am considering sending it back, assuming the seller would even allow the return.
