This guide will address the issue where the Bitmain Antminer D7‘s hash rate is ZERO but can be recovered by restarting.
Issue: after running for a period of time, the Bitmain Antminer D7’s hashrate shows “0”. Rebooting can assist in restoring the hashrate, though.
Possible causes and solutions:
1. High-temperature protection
Verify that the Bitmain Antminer D7’s temperature is within a normal range by checking it. The max operating temperature of Bitmain Antminer D7 is 75 degree Celsius.
2. PSU might have issue
If the miner status shows all chips “x”, test by replacing with a good known PSU. In the interim, make sure the power input voltage ranges from 210V to 240V.
