Frequently Asked Questions
How accurate is this repair cost estimate?
This estimator is based on our experience repairing over 2,500 ASIC miners since 2016. The ranges reflect typical costs for each issue type, adjusted for your specific model. However, the actual cost depends on the exact components that need replacement, which can only be determined through hands-on diagnosis. D-Central always provides a firm, itemized quote after diagnosis — before any work begins. You never pay more than the quoted amount.
How do I ship my miner to D-Central for repair?
Package your miner securely in its original box or a sturdy box with adequate padding (foam, bubble wrap). Remove any aftermarket modifications and include a note with your contact information and a description of the issue. Ship to: D-Central Technologies, 1325 Rue Bergar, Laval, QC H7L 4Z7, Canada. We recommend using a carrier with tracking and insurance. For customers outside Canada, ensure proper customs documentation listing the item as “electronic equipment for repair” to avoid import duties.
Do you offer a warranty on repairs?
Yes. All D-Central repairs come with a warranty on the work performed and parts replaced. If the same issue recurs within the warranty period, we will re-repair it at no additional cost. The specific warranty duration depends on the repair type and is communicated with your quote. We stand behind our work — we have been in business since 2016 and our reputation depends on quality repairs.
What if the repair cost exceeds the miner’s value?
We will always tell you upfront if a repair doesn’t make economic sense. After diagnosis, if we determine that the repair cost approaches or exceeds the used market value of the miner, we will clearly communicate this and discuss alternatives — including sourcing a replacement unit, using your miner for parts, or exploring a partial repair to get some hashboards running. The decision is always yours.
How long does a typical ASIC repair take?
Most repairs are completed within 5-10 business days from the time we receive your miner. Simple issues like fan replacements or firmware recovery can be done in 1-3 days. Complex repairs involving chip-level work on multiple hashboards may take up to 15 business days. We will provide an estimated turnaround time with your quote. During peak periods, timelines may extend slightly — we always prioritize quality over speed.
What if I’m not sure what’s wrong with my miner?
That’s perfectly fine — and actually very common. Select “Unknown / won’t turn on” in the estimator, or simply describe your symptoms as best you can. Our diagnostic process is designed to identify the root cause. The diagnostic fee ($75-100 CAD) is applied toward your repair cost if you proceed with the repair. We will provide a detailed report of everything we find, even if you decide not to repair.
