Toronto & Ontario ASIC Repair Service — Ship Your Miner to D-Central

Running ASIC miners in Toronto, the GTA, or anywhere in Ontario? When your hardware goes down, you need a repair shop that knows mining equipment inside and out — not a generic electronics repair store that has never opened an Antminer. D-Central Technologies is Canada’s leading ASIC repair facility, operating out of Laval, Quebec since 2016. We serve Ontario miners through our fast mail-in repair service: ship your miner to us, and we will diagnose it, fix it, and ship it back — typically within 7-14 business days total including transit.

Ontario has one of the most active mining communities in Canada. Between Toronto’s tech-savvy population, the province’s expanding renewable energy grid, and growing interest in home mining and Bitcoin space heaters, Ontario miners are running everything from Bitaxe solo miners to full-scale Antminer S21 operations. But finding qualified ASIC repair in Ontario has historically been a problem — there are very few shops with genuine chip-level repair capability. That is where D-Central comes in.

How the Mail-In Repair Process Works

Getting your miner repaired from Ontario is straightforward. Our process is designed to minimize your downtime and keep you informed at every step:

1. Contact us — Call 1-855-753-9997 or email [email protected] with your miner model, symptoms, and any error codes. We will confirm the repair is worth pursuing and provide shipping instructions.
2. Pack and ship — Pack your miner securely in a sturdy box with ample foam padding (original packaging is ideal). Remove the PSU unless instructed otherwise — it reduces weight and the PSU is rarely the issue. Ship via Canada Post Expedited, Purolator, or UPS to our Laval, Quebec facility.
3. Diagnostics — Once your unit arrives, our technicians run full diagnostics: chip enumeration, voltage measurements, thermal testing, control board verification, and firmware checks. We identify every fault, not just the obvious one.
4. Quote approval — You receive a detailed breakdown of what is wrong, what needs to be repaired or replaced, the exact cost, and the estimated turnaround. No work begins until you approve the quote.
5. Repair — Our technicians perform component-level repairs: chip replacement, trace repair, voltage regulator replacement, thermal restoration, firmware recovery — whatever it takes.
6. Post-repair testing — Every repaired unit goes through extended burn-in testing to confirm stable hashrate, correct chip counts, proper temperatures, and reliable operation before it ships back.
7. Return shipping — Your repaired miner is securely packaged and shipped back to you with full documentation of all work performed.

Shipping from Toronto to D-Central

Toronto to Laval is approximately 540 km by road — one of the most well-serviced shipping corridors in Canada. Transit times are fast and predictable:

• Canada Post Expedited Parcel: 2-3 business days from Toronto/GTA
• Purolator Express: 1-2 business days
• UPS Ground: 1-2 business days

From other Ontario cities, shipping is equally reliable: Ottawa (2 hours from Laval by road), Hamilton (same as Toronto), London (2-3 days), Kitchener-Waterloo (2-3 days), and even Thunder Bay or Sudbury reach us within 3-5 business days.

Shipping tips:

• Remove the PSU to reduce shipping weight (saves $10-$20 on shipping)
• Use the original box and foam if available — ASIC miners are heavy and need proper padding
• Include a note with your name, contact info, and a description of the symptoms
• Add shipping insurance — your miner is valuable equipment
• Request a tracking number and share it with us so we can watch for your package

Common Repairs for Ontario Miners

The most common issues we see from Ontario-based miners include:

• Hashboard failures — Missing chips, low hashrate, one or more boards not detected. This is the #1 repair we perform across all manufacturers.
• Overheating and thermal shutdowns — Common in garage and basement setups where ambient temperature or airflow is not properly managed. We repair the thermal damage and advise on setup improvements.
• Power surge damage — Ontario’s grid, especially in rural areas, can deliver voltage spikes that damage control boards and hashboards. We diagnose and repair surge damage at the component level.
• Fan and cooling system failures — Worn fans, connector damage, fan controller faults.
• Firmware corruption — Failed updates, corrupted flash memory, boot failures.
• Control board issues — Network connectivity drops, hashboard detection failures, erratic behavior.

Repair Pricing

D-Central repair costs range from $65 to $300 CAD depending on the diagnosis:

• $65-$100 — Fan replacements, firmware reflashes, connector repairs, basic maintenance
• $100-$200 — Single chip replacements, voltage regulator repair, thermal restoration
• $200-$300 — Multi-chip hashboard repair, complex trace damage, control board repair

You always receive an exact quote after diagnostics. No work begins until you approve the price. If a repair would cost more than the miner is worth, we will tell you — we are miners too, and we do not waste your money.

Turnaround Time for Ontario Miners

Total turnaround from ship-to-return for Ontario miners is typically:

• Simple repairs: 5-8 business days total (2-3 days shipping each way + 1-3 days repair)
• Standard hashboard repair: 9-14 business days total (2-3 days shipping each way + 5-7 days repair)
• Complex board-level repair: 12-20 business days total (2-3 days shipping each way + 7-14 days repair)

These are typical timelines — many repairs are completed faster. We provide a specific estimate with your quote, and we communicate proactively if anything changes.

3-Month Warranty on All Repairs

Every repair we perform includes a 3-month warranty on the specific work done. If the same fault recurs within the warranty period, ship it back and we repair it again at no additional cost. The warranty covers our workmanship and all replacement components we install. We stand behind every solder joint.

Frequently Asked Questions

How do I ship my miner from Toronto to D-Central?

Contact us first at 1-855-753-9997 or [email protected] to initiate the repair. We will provide our shipping address and instructions. Pack your miner in a sturdy box with foam padding, remove the PSU to save on shipping, include a note with your symptoms and contact info, and ship via Canada Post Expedited, Purolator, or UPS. Most carriers deliver Toronto-to-Laval in 2-3 business days.

Can I drop off my miner in person if I am in the Toronto area?

Our facility is in Laval, Quebec — about a 5-hour drive from Toronto. While some customers do make the drive (especially with multiple units), most Ontario customers use our mail-in service. The Toronto-Laval shipping corridor is fast and reliable, typically 2-3 business days each way.

How much does shipping cost from Ontario?

Shipping costs depend on the weight of your miner and the carrier you choose. A typical ASIC miner (without PSU) weighs 10-15 kg. Expect approximately $25-$50 CAD each way via Canada Post Expedited or Purolator Ground. We can advise on the most cost-effective shipping option when you contact us.

What if the repair costs more than my miner is worth?

We will tell you. After diagnostics, if we determine the repair cost exceeds the market value of the unit, we will give you an honest recommendation. You are never obligated to proceed with a repair. You only pay the diagnostic fee if you decline the repair, and even that is waived if you proceed.

Do you repair miners for commercial mining operations in Ontario?

Yes. While our focus is on retail miners and home mining operations, we accept repairs from commercial operations as well. For bulk repairs (5+ units), contact us directly to discuss volume pricing and logistics. We can arrange freight shipping for larger quantities.

Is the 3-month warranty valid for mail-in repairs?

Absolutely. The 3-month warranty applies equally to all repairs regardless of whether you dropped off in person or shipped from Ontario. If the same fault recurs within the warranty period, ship it back to us and we will repair it at no additional cost.
