How Much Does ASIC Repair Cost? Flat-Rate Tiers, Repair vs Replace & What Drives the Bill

ASIC miner repair cost in Canada ranges from roughly $95 CAD for a simple connector or fan swap up to $195 or more for chip-level hashboard work — exact pricing depends on what failed, which generation of chip is inside, and how many domains are affected. D-Central publishes its flat-rate pricing tiers before you ship anything; use the ASIC Repair Cost Estimator to get a model-specific range in under a minute.

The section below explains what those tiers cover, what actually drives a repair bill up or down, and how to decide whether a repair is worth it at all. If you already know you need service, request a free quote from our Laval bench.

The three repair tiers — what they cover and why

D-Central structures repair pricing around the complexity of the work required, not the brand on the front panel. Tiers are typical starting prices in CAD; the final figure follows diagnosis and is confirmed in writing before any work begins.

Tier	Starting price (CAD)	What it covers	Common examples
Level 1	from $95	Mechanical, thermal, and passive component faults that do not require chip-level work.	Damaged ribbon cables, loose or corroded connectors, fan replacement, thermal repaste / re-pad service, IP or connectivity faults, single failed passive components.
Level 2	from $145	Board-level work on PSU, control board, or single-domain hashboard faults.	APW-series PSU repair, control-board recovery and firmware reflash, a single failed LDO or boost stage, one dead power domain on a hashboard.
Level 3	from $195	Chip-level hashboard repair and multi-domain faults. Price scales with the number of failed chips and domains and the extent of secondary damage.	One or more dead ASIC chips (BM1368, BM1370, BM1398, BM1366, BM1387, etc.), multiple failed domains, boards that passed through a voltage event.

Prices are in CAD. Inbound and return shipping, and applicable taxes, are not included. The pricing page covers the exact component-by-component breakdown per model family (S19, S21, Whatsminer M30/M50, Avalon A12xx–A15xx).

Every repair includes diagnosis, labour for the quoted tier, parts for that fault, post-repair testing on a bench fixture at rated hashrate, and a 3-month repair warranty (7-day DOA). Diagnosis from $65 CAD is applied to the repair cost if you approve the job; if you decline, you pay only the diagnostic fee and return shipping.

What actually drives the cost up

Two repairs on the same model can land in very different tiers. Here is what the bench actually looks at:

Fault type and depth of damage

A loose ribbon cable is a 15-minute swap. A hashboard that failed partway through a voltage event may have multiple dead chips across several domains plus secondary damage to level-shifters and LDO regulators — that is a fundamentally different job. The tier reflects which situation you are actually in, not which one the symptom log suggests.

Chip generation

Newer ASIC generations pack more chips per board in denser arrangements. The S21 (BM1368) runs 108 chips in 12 domains; the S21 XP (BM1370) runs 91 chips in 13 domains. Sourcing the correct replacement chip and executing a clean rework on a modern fine-pitch QFN package requires more time and precision than work on an S9 (BM1387). Complexity scales with the generation, which is reflected in Level-3 pricing for newer silicon.

Domain count and secondary damage

A single-domain fault on an S19 hashboard (38 domains, 2 chips per domain) is a contained job. A fault that knocked out 6 of those 38 domains is a multi-chip, multi-component job at a different scale. If the failure also scorched a trace, burnt a connector, or spread to neighbouring circuitry, that becomes a line-item addition to any base tier.

Parts availability

End-of-life models — check the Antminer EOS Tracker — may have thin or zero spare-chip supply. When parts are scarce, sourcing time and cost affects the total. We will tell you up front if a model has a parts problem rather than take a job we cannot complete.

Shipping (not in the tier)

Inbound and return shipping are separate. ASIC miners are heavy (the S9 is roughly 5 kg; the S21 series approaches 10+ kg), and fragile boards need appropriate packing. Budget shipping as a real line item in your decision.

Repair vs replace: a decision matrix

Repair is not always the right call. Before you ship, run this check — or use the Warranty or Repair decision tool for a step-by-step guide.

Situation	Likely verdict	Why
Fan, cable, connector, or thermal issue on any in-production model	Repair (Level 1)	Low cost, fast, and the fix is durable. A machine you paid $2,000+ for should not go to scrap over a $20 fan.
PSU failure on a supported model	Repair (Level 2) or replace PSU	PSU replacement is cheaper than a full machine swap and brings the unit back to full capacity. Weigh a new APW PSU vs a repair quote.
Single-chip or single-domain fault on a current-gen machine (S19 XP, S21, M50-series)	Usually repair	Used market value of current-gen hardware typically well exceeds a Level-2–3 repair. The Used ASIC Price Index gives a live reference for comparable units.
Multi-domain fault on a legacy machine (S9, S17)	Run the numbers first	A chip-level repair on an S9 may approach the used value of another S9. Compare the repair quote to the price of a working used unit before committing.
Burn damage to a hashboard (scorched connectors, burnt copper)	Often decline	Burn damage is not safely repairable in most cases. We will tell you so before taking your money.
Manufacturer warranty still valid	RMA first	Use the manufacturer’s warranty if it applies — Bitmain’s standard warranty is typically 180 days from ship date. Independent repair voids the manufacturer warranty on most platforms; confirm before opening the unit. See the Warranty or Repair tool.
End-of-life model with no parts	Replace	If we cannot source the chip, repair is not feasible. Check the EOS Tracker before sending.
Repeat failures on the same board	Investigate root cause	A board that has failed twice likely has an underlying electrical issue (dirty power, overvoltage, inadequate cooling) that a single repair will not address. Fix the root cause first.

If you are on the fence, the Repair Cost Estimator gives you a model-specific range and the Used ASIC Price Index gives you a live CAD price for comparable hardware — together they give you the numbers for the repair-vs-replace calculation.

PSU repair: its own cost category

The APW-series PSU (APW3, APW7, APW9, APW12) is a separate and often overlooked repair category. A failed PSU can cause symptoms that look like hashboard failure — including zero hashrate, missing boards, and erratic sensor readings — so correct diagnosis matters before any repair work begins.

PSU faults typically fall in the Level-2 tier. If you have a PSU-specific failure, the ASIC PSU Repair Guide covers common APW failure modes, safety precautions, and what the bench does at the component level. Do not open a PSU without understanding the hazards; residual capacitor charge in a mains-connected supply is lethal.

Hashboard repair: what chip-level work involves

Chip-level hashboard repair is the most complex and most misunderstood part of ASIC service. The short version:

• Every Antminer hashboard is a daisy-chained UART chain. A break anywhere in that chain — a dead chip, a failed level-shifter, a bad LDO — can take an entire domain or the entire board offline. Diagnosis has to localize the break before any component is touched.
• Domain architecture varies by chip generation. The S19 (BM1398) runs 38 domains; the S21 (BM1368) runs 12 domains with 9 chips each; the S21 XP (BM1370) runs 13 domains with 7 chips each. A single-domain fault on a 38-domain board is a much smaller scope than a single-domain fault on a 12-domain board where each domain holds 9 chips. See the ASIC Hashboard Repair guide for the technical architecture.
• Chip replacement requires specialized equipment. BGA and QFN rework on ASIC chips requires hot-air rework stations, soldering microscopes, flux-cleaning, and re-balling or rebonding depending on the chip package. This is not hobby soldering; a bad rework destroys neighboring components.
• Testing after repair is not optional. We test on a board fixture and verify hashrate output at rated load before a board ships back. A repair that passes at the component level but fails under thermal load is not a repair.

How to estimate before you ship

1. Run the ASIC Repair Cost Estimator — select your manufacturer, model, and symptom to get a tailored range and an estimated tier.
2. Check the flat-rate pricing page — see the exact component-by-component menu and the policies it is drawn from.
3. Not sure what is wrong? Use the ASIC Fault Finder to identify likely fault types from your error codes or symptoms.
4. Compare to used market value via the Used ASIC Price Index to sense-check the repair-vs-replace decision.
5. Submit a repair request — our bench will diagnose first and quote before any work begins.

Frequently asked questions

How much does ASIC miner repair cost in Canada?

D-Central’s flat-rate repair tiers start at $95 CAD (Level 1: cables, fans, thermal service), $145 CAD (Level 2: PSU repair, control board recovery, single-domain faults), and $195 CAD (Level 3: chip-level hashboard repair). Final pricing follows diagnosis. Use the ASIC Repair Cost Estimator for a model-specific range, or see the full pricing page for the component-level breakdown.

Is it worth repairing an old ASIC miner?

It depends on the fault type, the model’s current used-market value, and parts availability. A fan or cable repair on any miner is almost always worth it. Chip-level repair on an old machine (S9, S17) is worth running the numbers on first — compare the repair quote to the price of a comparable working unit in the Used ASIC Price Index. The Warranty or Repair decision tool walks through the full logic.

What is not included in the repair price?

Inbound and return shipping are separate from the repair tier. Applicable taxes are also added at billing. If you decline a repair after diagnosis, you pay the diagnostic fee (from $65 CAD) and return shipping only.

Does ASIC repair void the manufacturer warranty?

On most platforms, yes — opening the unit or performing independent repair voids the manufacturer’s warranty. Bitmain’s standard warranty on new Antminer units is typically 180 days from ship date. If your unit is within that window, use the manufacturer RMA process first. The Warranty or Repair tool helps you determine which path applies to your situation.

How long does ASIC repair take?

Turnaround at D-Central’s Laval bench is typically 5–15 business days from receipt, depending on the complexity of the job and current bench load. This is an honest estimate, not a same-day guarantee. A correct repair comes before a fast one. We confirm a window with your quote and keep you updated throughout.

What ASIC models do you repair?

D-Central services every major platform: Bitmain Antminer (S9 through S21 XP and current generation), MicroBT Whatsminer (M30S, M50, M60-series), Canaan Avalon (A12xx–A15xx), and others. Dedicated repair guides exist for each family — see the ASIC Hashboard Repair hub. If a model is end-of-life, check the Antminer EOS Tracker for parts and support status before shipping.
