Eight Bitmain Antminer L7 log errors will be covered in this guide, along with solutions for each.
Table of Contents
1. Fan Error
If the log returns:：”ERROR FAN LOST: fan lost”
The fan then encounters a problem. It is abnormal if the fan speed is zero or differs noticeably from other fans. Simply change it.

2. Reading Temperature Error
If the log returns:” level=error pid=865 chain=2 error=”temp lost” msg=check_temp “
Temperature sensors on the hash board are typically to blame. Unplug and reconnect the wires to try and fix the problem. If that still doesn’t fix the issue, try returning it for repair.
3. High-Temperature Alert
If the log returns:” Fatal Error: Temperature is too high “
The temperature inside your mining rig is exceeding the safe operating limits. Finding the primary causes of high temperatures is crucial. Approximately two minutes after turning off the electricity, restart the miner. However, due to the high-temperature protection mode, if the surrounding temperature rises too much, the Bitmain Antminer L7 will still halt operations and shut down.

3. Lost of Chips
If the log returns:”chain=2 msg=”ChipSetting_get_addr_LTC detect 0 chips”or”level=notice pid=875 chain=2 msg=”ChipSetting_get_addr_LTC detect 0 chips””
The chips are typically not discovered. May be fixed by unplug and reconnect the wires. Try sending it back for fixing if that doesn’t resolve the issue.
4. Data Storage Error
If the log returns: “EEPROM eeprom_key_version or eeprom_encryption_algorithm error!”
Usually brought on by the storage chip exception on the hash board. Try card flash before send back for fixing.
5. Version Error
If the log returns:”level=error pid=23808 msg=”chain_offset 1, chain 1, get_sw_version error!”
Normal causes include abnormal hash board version information. Before returning for repair, try replugging the cable or card flash.
6. Pool Connection Error
If the log returns:” stratum connection timeout “or” level=error pid=879 poolno=2 msg=”…retry after 30 seconds failures 1″ “
Typically, a connection to the pool is to blame for the error. Checking the internet and the pool is necessary. Be aware that an unstable connection might be to blame. Even when Bitmain Antminer L7 miners can operate well, we’ll need to check the internet and the pool.
7. Internet Error
If the log returns：” level=fatal pid=22126 error=”net lost” msg=”lost internet 1200 seconds > 20 minutes, poweroff.” “
Typically brought on by an internet glitch. Verify the internet settings.
8. Setting Error
If the log returns: “Most likely you have input the wrong URL, forgotten to add a port, have not set up workers, or the network was disconnected.”
Typically brought on by inaccurate or incomplete pool input information. Check the settings for the pool.
