Questions about our mining repair services?


We answer your questions about our mining equipment repair service.
Contact our support team to learn more about our hashboard repair solutions if your question remains unanswered.

Yes, an ASIC miner can be repaired. Depending on the type of mining machine, there are a variety of repair services available to choose from. Generally speaking, we offer repairs for control boards, power supplies, hashboards, temperature sensors and other components that could be causing your miner to malfunction. We have all the necessary parts and tools to properly diagnose and repair the device. In addition to offering fast turnaround times, we accept payment via bank transfer, credit cards and other methods such as cryptocurrency payments. 

Some manufacturers such as Bitmain offer additional services when it comes to repairing their Antminer machines. They have a service center in China which offers repair work for their miners as well as technical advice for specific matters like installation and use of the machines. Through their website you can request a repair service by filling out a form with information about the location and address of your mining equipment

D-Central’s experienced technicians are available to test and diagnose miner issues while customers can track process updates online. It should also be noted that depending on the type of repairs needed prices may vary so it is best to determine pricing before any work is performed or related deals are made. While most manufacturers offer warranties on their products, it’s not so clear that this option will save you money as they normally require the complete machine to be sent back to China. This process is not only costly in shipping, but also very time consuming. Most often, paying for the repair yourself will cost less than honoring the manufacturer’s warranty.

Basic repairs are the first steps in repairing your miner. We will ultrasonic clean all of its hashboards and do a complete dusting of your fans, case, control board and power supply. We then start troubleshooting and diagnosing all your hashboards and proceed to replace the necessary parts up to a certain quota. For example, if it needs new chips, we will replace up to 5 chips per hashboard before considering it a No-Fix. The replacement of a non-recoverable component added to this service will be added to the invoicing.

We also offer fast turnaround times. Our prices are competitive in the industry, so customers can feel confident knowing they are receiving a quality repair experience for a reasonable price. Our technical team has years of experience in the mining industry. We are familiar with all the major manufacturers, such as Bitmain Antminer, and can repair their miners quickly.

Our basic repairs offer a full range of miner repair services, including diagnosing and repairing power supplies, temperature sensors, boards, and more.

Maintaining an Antminer is a necessary process to keep the device running smoothly. In order to maintain your Antminer, you need to follow some simple steps and be familiar with the basic concepts of mining. You should also have access to technical support in case of any problems. The following guide will help you through the basics of Antminer maintenance.

First, you should always make sure that your Antminer is properly cooled. The fans on the device must be kept clean and clear of debris, and the ambient temperature should be monitored to ensure that it does not exceed safe levels. If necessary, you can add additional cooling fans or install air conditioning to keep your miners running optimally.

Second, you should regularly check all cables and connectors for damage or wear. Damaged cables can result in reduced performance or even complete failure of your miner. If any connectors are loose or corroded, they should be replaced immediately.

Third, you should monitor the status of your miners and report any issues as soon as possible. Regularly checking temperatures, fan speeds, and other parameters can help prevent minor problems from becoming major ones later on. If there are any errors detected by the miner, they should be investigated and addressed as soon as possible.

Fourth, you should be familiar with the local repair centers and services that can help you maintain and repair your miners. Many companies offer dedicated support for Antminers, offering fast turnaround times, experienced technicians, and necessary parts or tools to get your miner running again as quickly as possible.

Fifth, you should always keep a record of any repairs or maintenance work performed on your miner. A clear and accurate record will help you identify where problems occur and how they were addressed. This will also provide useful information when making decisions about future repairs or upgrades to the device.

Finally, you should arrange payment for any service or repair fees upfront in order to ensure that there are no delays in getting the work done. Many companies now offer services such as bank transfers or money orders to make payment easy and reliable.

Taking the time to properly maintain your Antminer will ensure that it runs smoothly and reliably for years to come. By following the above steps, you will be able to get the most out of your miner and avoid costly repairs or downtime. If you ever encounter any issues with your miner, contact an experienced service center right away in order to diagnose and fix the problem as quickly as possible. With diligent care and attention, you can maximize the performance of your mining rigs while keeping them running safely and efficiently.

If you’re experiencing problems with your Antminer 17 series miner, one possible issue could be that the heatsinks are missing. This is a common problem with the Antminer 17 series. The copper plating on top of the chips delaminating causes this. This delamination of the copper is also due to the poor quality of the solder during the manufacturing of these machines. Since very little TIM allows good heat transfer from your chips to the heatsinks, the copper plating peels off the top of the chip, and the heatsinks follow. Your machine cannot mine even if only one heatsink is missing.

You have two solutions, either a repair that requires replacing all the delaminated chips on your hashboard or replacing the original heatsinks for our improved all-in-one heatsink upgrade, which ultimately protects you from this problem. Either way, this will be treated as a repair and, depending on the number of delaminated chips, may even involve an advanced repair, which is billed at an hourly rate + our base flat rate.

For more information about our repair process, contact us today! We will help arrange delivery or pick-up of your miner with ease, determine the cost of repairs, and deal with all related pricing issues.

Bitmain offers a 1-year warranty on all of their products. If there is a problem with your miner, you can contact Bitmain’s customer service department to have it repaired. In some cases, you may need to send the miner directly to Bitmain’s repair center in China. However, if the problem is with the control board or power supply, it is counterintuitive and frustrating to send the entire machine in for repair in China. The process for repairing miners can take some time, and the transport on top makes it even longer. To add on top the shipping costs are prohibitive. Using a local repair shop that offers hashboard, power supply and control board repairs is the most convenient way to get your miner repaired, but repair charges will be billed to you.

Local repair shops can also offer services such as miner maintenance and independent individuals may be able to diagnose, fix, or arrange the necessary repairs. Depending on the location of the repair shop, they may even offer free pickup/delivery so you don’t have to wait around while your machine is being serviced if it needs to be sent in for repair.

The cost of repairing miners varies based on what type of equipment is needed and how much labor is required. Prices range from just a few dollars for minor fixes like replacing temperature sensors, up to several hundred dollars for complete machine rebuilds. If you are paying for a repair, make sure to ask questions and get an estimate of the cost before committing to repairs.

Repairing your Bitmain Antminer is no small task, but with the right tools, resources, and knowledge it can be done quickly and affordably by experienced technicians in the mining industry. Most importantly, make sure you understand what it will take to fix your miner so that you don’t end up spending too much money on unnecessary repairs.

At our mining device repair center, we have the experience and expertise to handle a wide range of repairs on all types of mining devices. However, there are some repairs that we cannot perform. We do not offer repair services for hashboards or units containing traces of burns, silicon to hold heatsinks, or any form of glue that prevents the signal from being detected. These repairs are typically more difficult and expensive, and in many cases are not worth the investment.

There is a large volume of machines bought in China which contains only glue or silicon and which burns your chips within hours of use. We advise you to get reimbursment from the sellers of these machines which are nothing short of scams. Machines which have several delaminated chips/heatsinks missing or which need replacement of more than 5 chips are disqualified on a case by case basis, depending on the level of difficulty and the cost of the repair, it may happen that we will tolerate such a repair, it will however be longer and not be a priority.

ASIC miners are devices that are created for a single task and they do it very well. That is why they are used in the mining industry. However, these machines have a limited lifespan and eventually need to be repaired. The repair process can be costly, but there are companies that offer this service at a reasonable price.

Antminer repair services can be done by an independent individual or a service center. If you choose to have the repair done by an individual, you should make sure that they are qualified and experienced in the field. If not, there is a risk of them damaging your machine further.

The power supply and control board are two of the most important parts to get repaired when it comes to Antminer repairs. Service centers usually have the necessary equipment and technical expertise to diagnose, repair and test these components if needed. They also offer warranty coverage for their work in case something goes wrong with your mining device during the repair process.

With proper maintenance and professional repairs when there is an issue, your miners can keep generating revenue for a long time. The cost of repairs is determined by the manufacturer, however most companies offering the service will have competitive prices compared to buying a new machine.

When a temperature sensor in an Antminer fails, it is important to know what to do. One or more of your temperature sensors may need to be replaced. In some cases, it could also be chips around the temperature sensor not reporting the correct values and may require chip replacement. We have also witnessed cases of corrosions and broken traces which prevent the temperature rise signal from passing through. You can send your ASIC miner to our repair center where we will promptly replace your sensors, test all chips, and prepare your board for hashing.

The repair process could involve testing for power supply issues, checking boards and components related to temperature sensors, replacing defective equipment or repairing individual components. Once testing is completed and any necessary repairs have been performed, we will fill out any related paperwork as well as offer warranty support if needed.

It’s important to note that the amount of down time will depend on how quickly parts are acquired and how fast repairs can be completed; however, most of the time we will be able to provide an accurate estimate based on our years of experience in the mining industry. Our repair services for miners also include technical support throughout the entire process.

If you’re having issues with your Whatsminer, don’t worry – help is available. We will walk you through the process of repairing your miner, from identifying the problem to getting it back up and running.


We offer support for power supplies, control boards, temperature sensors and more. We can help you identify the issue quickly so that we can get started on repairs as soon as possible. Our mining equipment repair services include complete machine maintenance, and our expert technicians will be able to diagnose any problem your miner may have. We offer fast turnaround times for repairs, with most repairs being completed within 14 days.

Just like unrecognized chips, it can also be a power distribution problem, a first or last chip problem, or even a chain break that prevents the signal from getting through and requires the replacement of several parts. We can definitely solve this problem.

The prices vary between them according to the level of difficulty of a repair, the number of points of failure and our experience with models that are more problematic than others. Second, the prices of the parts themselves are bound to have a direct impact on our pricing. This is why our prices can also vary over time, if a shortage of chips is felt as it is now, the prices of parts unfortunately increase, making the repair more expensive.

For tickets with less than 8 machines, we have an average processing time of 2 to 4 weeks. For tickets over 8 machines, this is assessed on a case-by-case basis, but we normally process the volume within 6 weeks. We now have a team of over 30 qualified technicians ready to serve you. Follow the progress of your repairs in real time on our repair portal. For more information on processing and timelines, contact our support team, which responds within 24 hours on business days.

We install warranty seals on repaired machines. If you open the machine during its coverage period and the seals are broken, your machine will lose its coverage. We install seals against humidity or water damage on your hashboards, if these sensors are activated, the cover is broken. Any trace that your equipment has been used in an unsuitable context and that the manufacturer does not cover may be refused. Finally, if you overclock your machine, in particular by using an after-sales service firmware, we reserve the right to refuse to honor our repair warranty. Consult our support team before doing any prescribed manipulation to avoid misunderstandings.

If you have several machines with only 1 defective hashboard, we simply advise you to group the good hashboards in the good machines and the bad ones in the bad machines and finally send them to us. However, sometimes some of our individual clients only have one hashboard to fix in total. In these cases, we invite you to join us and we will deal with you on a case-by-case basis. We normally do machine repair processing and not an individual hashboard for several reasons. We have a long history of providing service for individual hashboards, but several variables become beyond our control, such as machine condition, machine firmware, repaired component re-insertion, shipping, etc. Finally, if you bring us the complete machine, the repair price remains applicable for the machine, because it often happens that by opening the machine and cleaning it, certain weaknesses become more apparent and require intervention. Failure to take this action may result in problems with your machine for which you will hold us responsible. Thus, we offer a repair service applicable to complete machines, regardless of the diagnosis you have carried out beforehand.

Upon reception of a service receipt, I grant permission to D-Central to perform any action deemed necessary in an attempt to repair my device. Furthermore, I release D-Central from any liability for any data loss which may occur, or component failures occurring during attempted repair, testing, or at any other time. D-Central is not responsible for loss of profit or any direct, indirect, special, incidental, or consequential damage occurring during or after device service, including during transport. I realize that D-Central will repair the apparent damage for the immediate functionality of my device, but cannot restore it back to new equipment, as it is used and has been damaged. Therefore, D-Central cannot guarantee its durability beyond the components that have been worked on during the repair. However, D-Central being confident in the quality of its repairs, a 30-day warranty is offered on unit repairs, if the warranty seals are left intact, but remain entirely up to D-Central’s discretion for individual hashboard repairs. I agree to take on all shipping charges, including for warranty repairs. D-Central is not responsible for any failures or delays in performing the service agreed upon. I accept that a 30$ per hashboard repair attempt fee will be charged if my device cannot be repaired, to cover diagnostic and the resources used in this attempt.
Upon first notice of completion, by phone and/or email, I agree that a 30-day period is
granted for me to claim my device, after which storage fees will be added to my invoice.
These fees are established at 15% of the amount receivable for my repaired device, divided
into 3 months remittance, with an additional 10$ base fee per month. As the law states, any
unpaid or unclaimed device, within 90 days of an official notice of completion, will be
considered abandoned and therefore become D-Central’s property.
