Bitmain Warranty Denied? We Repair “Scrapped” S21 & L9 Hashboards in the USA
By Aleksandr (Alex) MuranovShare
Bitmain warranty denied and your S21 Pro / S21 XP / S21+ / L9 board got labeled “scrap” or “unrepairable”? If there are no visible burn marks (no charring/blackening), we can still attempt a component-level repair in our USA lab (Florida). Typical turnaround is 4–5 business days. If your non-burned board can’t be repaired, we’ll credit $100 service-only store credit for that board.
When Bitmain Says “Scrap” or “Unrepairable”, What Does It Usually Mean?
Bitmain uses “scrap” language when they believe the board is not economical or not possible to repair under their after-sales process. In practice, users often see denial outcomes tied to physical/chemical damage (burning, corrosion/oxidation), “mixed board” situations, shipping damage, or other conditions that can void warranty.

Our Policy: We Take Rejected Boards (If They’re Not Burned)
We’re a USA-based repair shop in Florida and we accept mail-in repairs from all states. We focus on component-level diagnostics and board repair for modern miners where downtime is expensive.
Eligible models
- Antminer S21 Pro hashboard
- Antminer S21 XP hashboard
- Antminer S21+ hashboard
- Antminer L9 hashboard
Not eligible (automatic reject)
- Visible burn damage: charred/blackened PCB, melted areas, blown traces, obvious scorching
- Boards physically destroyed beyond safe handling (cracked PCB, missing large sections, severe mechanical damage)
Important: If you’re unsure, send intake photos first or include a note in the box. We’ll confirm eligibility during intake.

- 🔧 Component-level diagnostics (power rails, domains, shorts, ASIC chain behavior)
- ⚡ 4–5 business days typical turnaround once the board is received (most cases)
- 🧪 Testing under load where applicable before we sign off

$100 Store Credit Guarantee (Service-Only, Per Board)
If Bitmain rejected your board as “scrap/unrepairable” and it has no visible burn damage, we’ll attempt repair. If we determine it’s not repairable after diagnostics, we will dispose of the board (we agree it’s effectively scrap) and issue $100 store credit per board.
Hard disclaimer (read this twice): The $100 credit is STORE CREDIT ONLY. It is not cash, not refundable, not transferable, and cannot be withdrawn or converted to any payment method. It can be used only for repair services on our site. It does not apply to physical products (fans, chips, parts, accessories, etc.). The store credit does not expire.
Real-world case: Bitmain “Scrap” S21 XP Hashboard Saved
Here’s a real example of why “scrap” doesn’t always mean “impossible.” Bitmain denied warranty for an S21 XP hashboard and labeled it as scrap. The customer sent the board to us. After inspection, we found 12 burned ASIC chips that needed replacement. In cases like this, Bitmain typically denies warranty.

Cost breakdown (example)
- Board repair: $350
- ASIC chips: 12 × $30 = $360
- Total repair cost: $710
A brand-new replacement board from our partners at Altair was $1,149.
Savings vs buying a new board
- New board: $1,299
-
Repair (no discount): $710
- You save: $589 (about 45.3% vs new)
Savings if the 30% program discount applies
- Repair labor after 30% discount: $350 − 30% = $245
- ASIC chips: $360
-
Total repair cost with discount: $605
- You save vs new: $694 (about 53.4% vs new)

Why Warranty Gets Denied (Most Common Reasons Users Run Into)
This is a practical list of what we see customers searching for after a denial, and what often shows up in “scrap/unrepairable” decisions:
1) Corrosion / oxidation / moisture damage
- Humidity exposure, contaminated air, condensation, or “invisible” oxidation that becomes obvious under inspection
- Corrosion can trigger “scrap” decisions even when the miner looks “fine” from the outside
2) Burn marks / overheated power circuits
- Burned PCB areas, blown traces, burned connectors, burnt smell or blackened components
- This is the most common “no-go” category for any serious repair attempt
3) “Mixed boards” and parts provenance issues
- Boards swapped between miners, hybrid builds, or anything that makes original configuration unclear
- This is extremely common in hosting environments and can lead to warranty denial
4) Shipping / packaging damage
- Boards can crack, deform, or suffer impact damage during transport if not packed correctly
- Damage during shipping often turns into a warranty dispute nobody wins
5) Process issues (tickets, delays, missing context)
- Repair ticket rules, long turnaround, unclear communication, or delays that push users into “what now?” mode

Conclusion
If Bitmain denied your warranty claim and labeled your S21 Pro / S21 XP / S21+ / L9 hashboard as “scrap” or “unrepairable”, it doesn’t always mean the board is beyond recovery. If there are no visible burn marks, we can still attempt a component-level repair in our Florida lab with a typical 4–5 business days turnaround. If an eligible non-burned board turns out to be unrepairable, we’ll dispose of it and issue $100 service-only store credit per board (store credit only, not cash, not transferable, does not expire).
