mfr said parts to seller next week. I love the miner, wish they sent spare parts with batch's. runs a sweet 56-66t on 2hu. normal mode.

Interesting. When one of my hashboards quit, the unit would do about the same ~50th/s but only for about 20 minutes before dying. Temperatures are misread, fans operate at incorrect speeds. Having 1 hashboard out essentially renders the whole unit unoperable.

Did you unplug the faulty hashboard?

luckily, I did not have to unplug bad HU or board to continue to mine. Seller let me know there is firmware to allow to mine on good boards. since I was able to get machine to mine, I would not commit to trying to update firmware. My version is below. I did out of frustration do a factory reset and that was a nightmare for me. I had a hard time getting my pool back into system but it ended up being a stupid mistake on my part. looking into the manual thats on mfr site, I can say, I would not want to update firmware, afraid to make a mistake and ruin machine. good luck! I have since given seller info and waiting for them to ship me a HU.

I was to the point of sending a hash board to blokforge, sent them all they wanted. right before they sent me approval, I had moved the machine and when I plugged it in, Bam! everything is fine! kinda crazy, makes me think firmware upgrade they offer may be in order. I'm not interested in doing that yet, don't wanna screw it up and have a dead unit. As far as disassembly, super easy. They sent my a Avalon video link. I had already removed hash unit previously to look for hardware issues. The unit was quite dusty in the short time used maybe 40 days or so. I removed and cleaned everything this eve. In the future I plan to just remove the fans and blow the dust out from the exhaust side. how often do farms clean their rigs? looks like it will be monthly for me. mfr didn't skimp on the grey thermo paste. its like working with antisieze, gets everywhere.
NOTICE: you do not have to remove but two screws and the connector to remove a board. the video is for complete breakdown of machine and they remove control board and everything. Careful removing fans on inlet side, the temp sensor is there and kinda fragile. also fans are best kept on fan plate, not necessary to remove each one. Top panel slides off.

Have you contacted the distributor or Canaan?
What is the line voltage feeding the miner? It must be between 208 -240VAC.
The Avalons are very easy to work on and odds are that if a replacement part is needed it will be sent for you to replace vs sending the miner in for warranty repair.

Does someone have contact for Canaan technical support/repair? I have one under warranty that needs repair and I’ve been struggling to find a contact.

Thanks!

Hi Guys

I want to tell you about my experience with this matter recently and to hear your opinions about it



At the beginning of September, my father and I traveled from Guatemala to Arizona specifically to buy 4 Avalon 1246 of 85th from blockforge, at the time of the trip me and chase exchanged quite a lot of messages regarding the miners.

after we arrived at the company everything was great it looked like a legit company ( and it is !!)

So we decide to buy the miners as expected from the HK warehouse

- from the beginning chase always said "the miners are properly tested before shipping to make sure everything is fine " and we trust him

A couple of weeks later we received the miners in Guatemala and the first miner that gets plugged in and log into shows the exact error that you all are talking about.
-long story short 2 out of 4 miners had the same issue.

Naturally, I talk with Chase, he sends me the firmware update, and of course, the 2 miners still had the same issue.

I send them the logs and everything that they need and te told me "it is a warranty-covered issue we will talk with Canaan to resolve this "




Its been 3 weeks and they still saying "we haven't heard from Canaan sorry "


I believe that it's not fair nor ethical to hide under Canaan when they said they tested them and that they as blockforge will give you a warranty for them, but truth be told I am not seeing that warranty nor support
for the miners.

I needed to vent this since I don't know what to do, today I asked for a refund if not taking care of the issue for next week, and we should put some pressure over them because since as we all know
time its money and I don't want to use them with the bad hasboard since I don't want to risk the "it no longer covered by the warranty"

Have a great day you all and keep mining ( with an actual good miner )





Update ---- 18 oct 2021

They finally told me that the hash boards were approved to be replaced with new ones so let's dive into this process
