The Most Common Problems on Antminer 19 Series

Table of Contents

In this blog post, we will discuss some of the most common problems that can occur when using the 19 series miner. We hope this information will help you avoid these issues and maximize your profits from mining cryptocurrency.

The problem of the “0 ASIC” error and unrecognized chips

The “0 ASIC” error and unrecognized chips are two of the most common issues with Antminer mining rigs. Weak or substandard solders can lead to failures and a “0 ASIC” error code (especially on older models – the 17 series had a 30% failure rate). It is also possible that this error results from a power distribution problem, a problem with the first or last chip in the chain, or a break in the chain preventing the signal from passing through. The repair may require the replacement of several parts, but it is solvable.

Missing Heatsinks

If your Antminer is missing heatsinks, it’s important to take action as soon as possible. Heatsinks help dissipate heat from the chips, and if they’re not present, the chips can overheat and fail. In some cases, the machine may even shut down automatically to prevent damage. If your miner is missing heatsinks, you should have them replaced as soon as possible.

Wear and Tear of ASIC chips

Cryptocurrency mining puts a strain on the chips, which do all the work, which can often lead to failures. Your hashboard will need repairs ranging from chip replacement to a complete chip reflow. Due to the silicon lottery, not every ASIC chip has the same reliability and computing power. The silicon lottery refers to the inherent differences between two ASICs from the same product line. This means that your chips are going to work differently on the board. At some point, some chips will have different life cycles. This is why each chip must be handled with care.

Bad temperature operating range

Freezing temperatures or overheating can prevent the Antminers T19, S19, S19 Pro, S19j Pro and S19 XP from working. These models have temperature safety features that detect when the machine is drawing air through its fans below 23°F (-5°C) or above 185°F (85°C) and l ‘sends in protection mode. This automatically shuts down hash tables reporting low or high temperatures. It is theoretically possible to safely operate your machine between 32°F (0°C) and 104°F (40°C), but Bitmain recommends ambient temperatures between 59°F (15°C) or above. 95°F (35°C). Be sure to regulate the ventilation, heating and cooling of the environment while ensuring free air circulation around each miner.

Dust or Clogged Fans

Fans get clogged with dust, and when they seize up, your miner can quickly overheat and burn out or crash. Dust buildup on the heatsinks and hashboards will alter airflow, impact heat dissipation, and reduce efficiency. Dust can be one of the most debilitating bitcoin mining problems and accelerate component deterioration. A simple blast of air can help but trust a professional for disassembly and deep cleaning. The first step in every basic ASIC repair operation is an ultrasonic cleaning and thorough dusting of all fans, cases, control board and power supply.

Issues With Thermal Paste

When Bitmain released the S19, there were some reports of machines running hot. This was likely due to the use of substandard thermal paste. Thermal paste is used to help transfer heat from the chip to the heatsink. When it is not applied properly, or is of low quality, this heat transfer can be inhibited, leading to overheating.

Temperature Sensor Problems

Temperature sensor problems are another common issue with Antminer mining rigs. If the sensors are not working properly, the miner will not be able to regulate its temperature, which can lead to overheating and component failure.

Unstable Power Supply

An unstable power supply is one of the most common problems with Bitcoin mining rigs. If the power supply is not stable, it can cause the miner to overheat and break down. In some cases, it can even damage the chips.

Bad bonds, rust and corrosion

Mining hardware is subjected to a lot of wear and tear, often leading to breakdowns. One of the most common causes of these breakdowns is bad bonds, displacement of resistance capacity, rust, and corrosion. These issues can have various negative effects on the miner, including reduced efficiency, overheating, and component failure.
