1. Warranty Coverage & Duration
Used ASIC Global sells new and used mining equipment; it does not manufacture the third-party brands offered on the Website. Warranty coverage therefore depends on the condition stated in the order.
- New hardware: Covered by the original manufacturer's warranty stated on the product page or order. We will provide reasonable claim-coordination assistance, but the manufacturer determines eligibility and remedy under its warranty.
- Used hardware sold by Used ASIC Global: Covered by our limited used-equipment warranty for 365 days from shipment, whether the listing states that the unit required repair or required inspection and testing only.
- Hosted used hardware: The same limited warranty begins on the recorded activation date. Covered repair or equivalent temporary hashrate may be provided under the hosting terms.
- Third-party hardware: Hardware not purchased from us has no Used ASIC Global sales warranty and may be accepted only for paid diagnosis or repair.
- Used-equipment coverage: A verified internal hardware failure that is not caused by an exclusion below, a unit received non-operational, or delivery damage reported within the required period.
- Resolution: Remote diagnosis, parts shipment, repair or an equivalent replacement, selected according to the technical findings.
2. Return Merchandise Authorization (RMA) Procedure
If inspection confirms a fault covered by our used-equipment warranty, Used ASIC Global repairs or replaces the affected component without diagnosis, labour or parts charges. The target is completion within 10 business days after receipt at the service location assigned in the case. If that target cannot be met, we provide a written update and an equivalent replacement or confirmed completion plan.
Steps to Request Warranty Repair:
- Log in to your account or visit Serial Support & Repair.
- Enter the device serial number and order details to check coverage and generate an RMA reference.
- Package the defective component (hashboard, control board, PSU, or full unit) securely in anti-static protective packaging.
- Ship the package to your assigned regional repair hub with the RMA Ticket clearly marked on the exterior carton.
3. Shipping & Customs Terms for Warranty Repairs
RMA freight charges and customs logistics are governed by the following clear policy:
- Inbound Freight: The Customer pays to send the authorized warranty return to the service location stated in the case.
- Return Freight: Used ASIC Global pays the standard return delivery after covered repair or replacement.
- Customs: We provide accurate repair-return documentation. For an order of up to 10 devices originally sold as DDP/Tax Included, we coordinate the applicable return clearance. Larger commercial cases follow the written quotation or service instruction.
4. Warranty Exclusions
Damage caused by unsupported software, third-party overclocking or altered voltage may be excluded from warranty coverage. An unrelated modification does not automatically exclude coverage unless it caused the fault or prevents reliable diagnosis.
- Physical damage caused by improper electrical wiring, high-voltage surges, lightning strikes, or liquid immersion.
- Operating hardware in corrosive environments, unventilated spaces, or ambient temperatures exceeding specified technical limits.
- Burnt hashboards or chips caused by inadequate cooling or faulty third-party power supplies.
- Removal or tampering with original product serial number barcode stickers.
5. Out-of-Warranty Technical Services
A $49 remote diagnostic fee applies to out-of-warranty devices and devices not purchased from Used ASIC Global.
The remote diagnostic session may include review of network visibility, logs, temperatures, power and hashrate behaviour, controller configuration, error history and safe corrective steps. Remote diagnostic sessions are currently provided in English. Install AnyDesk from its official website. If the miner is powered and network-connected, the Customer computer must be on the same local network. If it cannot power on or connect, Support will arrange an alternative process and guide the Customer through preparation.
Remote access is used only with the Customer’s explicit approval during the scheduled session. Support will never request unattended access, account passwords, wallet recovery phrases, or private keys.
One reasonable rescheduling request may be accepted. Repeated absence or failure to prepare required access may close the session as delivered or require a new fee. A delivered diagnostic is non-refundable even if the issue is solved remotely. If physical repair is approved, the diagnostic fee is credited against the repair charge; inbound and return shipping, parts and labor remain the Customer’s responsibility unless the quotation states otherwise.
Customers receive a written quotation before paid work begins. Replaced components in an approved paid repair carry a 90-day service warranty.
