1.
Issue: The miner has no hash rate. One of the hash board’s temperature exceeds 80 degree Celsius.
Reason: A piece of heat sink is loose or dropped off.
Solution: Remove the hash board that exceeds 80 degree Celsius to repair.
Note: If large quantity of hash boards temperature exceeds 80 degree Celsius, please add cooling devices, as the high temperature will ultimately go into the high temperature protection mode and the miner will shut down. Moreover, the miner can easily get defective when working in a high temperature environment.
2.
Issue: The hash rate is good, but there is no temperature shown on the Miner status.
The hash board is easily burnt if there is no temperature shown for monitoring or when the real temperature is very high
Reason: The temperature detector is damaged on one of the hash boards that lead to the other two hash boards to have the issues on temperature display as well.
Solution: Test the 3 hash boards one by one by connecting to the control board and let it run for about 5 minutes, find the faulty hash board with temperature detection problem and ship it back to repair.
3.
Issue: The hash rate is lower than normal. There is an “X” shown on the Miner status.
Reason: The ASIC chip is damaged, which resulted in the loss of some hash rate on the hash board.
Solution: If that hash board can still work well, you can keep and continue to let it work. There is no need to repair it unless the hash board becomes totally defective.
4.
Issue: The hash rate is lower than normal. There are a lot of “X” shown on Miner status
Reason: The chips are damaged, which lead to the entire hash board running abnormally.
Solution: Remove the hash board to repair.
5.
Issue: The hash rate is lower than normal. There are a lot of “-” shown on Miner status
Reason: It may be caused by instability of the PSU voltage or a defective hash board.
Solution: Replace the PSU and control board-hash board 18 pin ribbon cable. If replacing didn't work, please remove the hash board to repair.
6.
Issue: The hash rate is lower than normal. Some chips are lost. The hash rate is only running at 2/3 of the normal.
Reason: Chain scission of chips
Solution: Remove the hash board to repair.
7.
Issue: The miner has no hash rate. There is X.X.X.X shown on the Hardware Version. Hash board cannot be detected. There is no information shown at all on the Miner status interface.
Cause: The firmware of miner is not detected.
Solution: Power off the miner and reset it. Reload the firmware.
8.
Issue: The miner worked great when it was powered. After awhile, there is no hash rate.
Reason: One of the fans is not detected. Miner will work well only when both fans are detected.
Solution: Switch the control board connection between the two fans to find out which one is defective.
9.
Issue: A large number of Antpools surfaced. Hash rate is normal. There is no use resetting the router.
Reason: One of the computers in the network has been infected by virus or malware.
Solution: Find infected computer and remove the virus or malware.
10.
Issue: Miner can’t find IP. Red light flashing; Green light does not blink
- Reason：The Miner is not connected with the Internet.
Solution: Test the Internet cable, connection and the settings of the Internet (DHCP mode is required).
- Reason: The miner program has not started.
Solution: Reset the miner several times.
- Reason: The application of miner is lost.
Solution: Perform control board recovery
11.
Issue: The miner doesn’t work after powering on despite changing the PSU.
- Reason: There is a short circuit inside one of the hash boards.
Solution: Find which hash board is defective. Remove the defective part to repair.
- Reason: Control board failure
Solution: Change the control board
12.
Issue: PSU can’t work when if the PSU fan is running. Miner works well after changing PSU.
Reason: The PSU is defective. The PSU fan is powered by a different output. The defect can’t be judged by whether the fan rotation power is normal.
Solution: Ship back the PSU to repair.
13.
Issue: Miner restores to factory setting after powering off.
Reason：The software in BB board is damaged.
Solution: Perform control board recovery
14.
Issue: Miners work well for several month before it starts to malfunction.
- Reason: The hash boards were corroded by humidity and lots of dust.
Solution: Remove the defective hash boards, dust the miner and reduce air humidity.
- Reason: Large amount of dust, resulting in congestion in the air duct. Heat can’t be dissipated. Catkins are likely to cause congestion in air duct.
Solution: Remove the defective hash boards, dust the miner and add dust elimination.
15.
Issue: The machine is defective when network changed
Reason: Due to the network setup, miner can’t find the IP.
Solution: Power off and reset the miner.
16.
Issue: S7 malfunction after running for a while. It runs again after rebooting.
-Reason: Temperature exceeds 80 degree Celsius and miner will automatically shut down.
Solution: Increase the amount of air flow.
- Reason: The PGA in BB board weld badly, which lead to miner’s shut down.
Solution: Remove the BB board to repair.
17.
Issue: PSU can’t work but fan is running. All the indicators are off.
Reason: The control board cannot get power as the power circuit in IO board is damaged.
Solution: Switch the BB Board and IO Board with good miner to troubleshoot the defective parts.

help
my antminer a3 didnt show chain# 3
The current PSU is 1600 watt. You think I can hook up my 750 watt to power the third board? I don't know why, it just feels like it would have to be the same wattage. I have no knowledge to base that on.
This is horrible news. It seems like if the other two boards are working fine then sending a replacement board would be the best option. I am still under warranty but I really do not want to send the whole machine back and pay shipping in addition to losing the mining profits and risk more damage or the miner getting lost in the mail. This sucks. I talked bitmain up a lot and referred a lot of friends and now I am really worried. I was told by support when I ordered that these machines should last for years. I've taken great care of it and spent all this time and money for a costly return and headache? So bummed out right now. I don't even want the 2 L3+ I ordered. What's the point if they break so soon and repair is so hard? Wishing I never decided to mine right now guess everyone was right.
Help me
My D3 after 1 - 2 day chain 2 not working , many HW and hashrate down 0.5 GH - 0.7 GH
no 1month yet.
earning very lower :(
Dear Bitbitbears:
I am a customer just like you, Do you relize that most of china is on holiday for new years?
I have left many support tickets, average response time for first response is 7 to 10 days, from then on each question added to the ticket is responded within 24 hours most of the time. If you see one hashboard without red lights on it, it is most likely a faulty (dead) hashboard, and will have to be sent in. After i sent a miner in, it arrived on december 23, of course with christmas i was not expecting them to scan the package right away, by December 28th they issued me a new miner and it is waiting delivery via fedex, the miner is currently 30 miles from my house but everything is shut down for new years.
Please give bitmain support some time to respond to your ticket be, as yours is not the only ticket they are helping with, Imagine 2000 tickets sitting on your email and you are only one person, Im sure thats the work load if not more of each support agent.
As for your sob story, Dont be stupid, only invest what you can afford to loose!
I am a long time customer of bitmain, going on 3 years now, i have had my issues, Never once had a complant, but i read peoples sob stories like yours over and over again about waiting 3 to 7 days for someone to read your ticket,
Please process my order

@Grand, thank you for your help. I just tried to download the newest firmware and nothing changed with chain 6. When I flashed the firmware all I got was a bunch of code after waiting a minute.
Hi everyone,
I have one PSU of following specifications, so to what Antminer it could be used!
Sorcerer Power Supply Unit Input 176 264V AC 15A MAX 50/60Hz 1600W 8 X 6-PIN
Thanks so much
Hi, My L3+ doesn't show any of the symptoms shown above and seems to be working fine has good hash rate, However for the last 2 days i have only been profiting 0.06 LTC in 24 hours
Thats barely $3.72, please advise, I have check and read all questions and answer, I don't seem to hear anybody having a similar problem

Daq79, that is great. No I haven't seen that problem, but it should be an issue with mining. I don't pay much attention to the temps (witch I should) my room stays at 40 degree c that my miners are in.
Not sure with account I logged into this is Kris kern :)
@Grand
Thank you very much for your kind reply
I did excatlty that you told me but now not even the status green light not bling and i cant get in even inside miner status on backstage. more over a red light r25 tf open on one of hashboard. i am really confused i tryied many times. any idea for this situation?
kris kern, thanks for the info. I will try it out in the morning.
@Adam Chow. Try reboot your modem @ router. And try again with the ip reporter.

The boards do have 2 led lights . Only one should be lighting up. Not sure what the problem is with 2 lighting up, at least you know the board is getting power and not completely dead. Try unplugging both the good boards. And use a ribbon cable from a good board on the bad board. I have found one wire pushed out of the connection on a ribbion cable. This can cause the board to not read proper.
Pato, if you look right below that if it starts saying other things, bmminer started. Try doing reboot, or flash new firmware and factory settings. After many reboots mine finally starting working
Hi Edward, we are sorry that the repaired board still did not work. We warranty our repairs for 45 days in addition to the original 180 day warranty. If we have not already replied to your ticket we will reply shortly.
Regards,
Barbara

Hi, I have 3 Antminer S9's with hashboards that are not working. This is now a total of 5 boards in 6 months. I could send this back as a warranty claim but I see that all the new machines have a different firmware version not available on the website. I suspect the problem has to do with the temperature sensors. The new software seems to not display one of the sensor readings and has an entry in the kernel log referencing a 'special fix'. So, can anyone tell me where I can get the below version of the firmware. Thanks.
the HW value is a little bit high but is ok, maybe it's just network instability.
[NEED HELP]
I'm having a Antminer S9, i found the IP via Report IP, login to control panel, configure the Static IP, but seems something goes wrong, and i can't login to control panel anymore.
I reset the machine few times, but can't search the IP via Report IP anymore.
Please help me, thanks
@mohdfaisalkhamli firmware has been update from bitmain sites ,, PSU original APW3++ by bitmain

@Paveen A,
Try powering it off and resetting your internet router. Sometimes mine will show false xxxx when I have a bad or lost internet connection.
Contact Barbara (Bitmain) <support@bitmainhelp.zendesk.com>
She is so helpful.
Pato. I had a 13.5 the start showing that same asic (#)#### then a few days later the hashboard died..
