Resolving Issues With the All-in-One Miner Power Supply

If your miner is not powering on, the fan doesn’t spin, and the network port light doesn’t light up, follow these troubleshooting steps:

Step 1: Confirm whether there is a proper connection throughout the whole line. All plugs need to be re-inserted, and ensure they are inserted tightly. Both power cord sockets need to be checked. If the fault still occurs, proceed with the following checks.

*Note: The power supply of the 17 and 19 series all-in-one machines requires dual power cords. The power supply can only output when both power cords are powered at the same time. If only one is inserted, the power supply has no output.

Step 2: Check whether the power supply fan rotates. If the fan doesn’t rotate, you need to inspect the power supply circuit.

Step 3: Begin checking the power supply line from the socket. Use a multimeter to measure the socket, and both sockets need to be measured. If there’s no voltage, ask an electrician to check the line and air switch. If you don’t have a multimeter, plug into and replace with a normally working socket to confirm.

Step 4: If the voltages of the corresponding sockets of the two power cords are normal, measure the output terminals of the two power cords. If there’s no voltage, replace the corresponding power cords. If you don’t have a multimeter, try to replace the power cords directly.

Step 5: If the voltage is normal, replace the power supply.

Step 6: If the power supply fan rotates, but the miner doesn’t turn on, first disconnect the power supply, open the miner and the upper cover of the power supply, unplug the power cord of the control board, power on the power supply, and use a multimeter to test whether the power supply line of the control board has 12V. If there’s no 12V, replace the power supply.

Step 7: If there’s 12V, disconnect the power supply, and re-plug the power cord and voltage regulator line of the control board. If the original fault still persists, replace the control board.

Step 8: You have now completed the troubleshooting process.
