Antminer replacement parts and repair tools

Antminer & Bitmain Replacement Parts and Repair Components

Antminer ASIC miners — manufactured by Bitmain Technologies — represent the largest installed base of Bitcoin and Litecoin mining hardware worldwide. When a hashboard goes down, a PSU stops switching, or a control board freezes, your hash rate stops generating revenue until the fault is fixed. Our Antminer parts catalogue covers every generation from the legacy S9 / S17 series through the current S19 line-up, the latest S21 / S21 XP / S21 Pro miners, and the L7 / L9 / KS5 alt-coin variants — sourced through Shenzhen channels with consistent quality control.

Common Antminer failures and the parts you need

When an Antminer S19, S21, L7, or KS5 stops producing hash rate, the failure almost always sits in one of four areas. Our catalogue covers each :

• Control boards (Amlogic A113D / C76 for S19j Pro / S21 / T21, BB-Beaglebone control boards for older S9 / S17 / L3+ generations, C87 overclocking board for L7 / S19 series) — when the miner won't boot, no IP, or kernel panic, the control board is the first suspect.
• Power Supply Units (APW17 for S21 / S19j XP, APW12 for S19 / T19, APW9 for S17 / T17, APW11 for hydro miners S19 / T19 / S21 hydro) — failed start-up, fluctuating voltage, or fan-only behaviour usually means PSU replacement.
• Hashboards, ASIC chips, and repair components — BM1397 (S17 series), BM1398 (S19 / S19 Pro), BM1362 (S19j Pro), BM1366 (S19 XP), BM1368 (S21 / T21), BM1370 (S21+) chip replacements ; capacitors, MOSFETs, temperature ICs, and stencil tools for hashboard rework.
• Cooling fans and adapters — 12cm 4-pin for S19 / T19 series, 14cm 6-pin for S21 / S19 XP and hydro models, plus fan speed simulators for immersion-cooled miners.

Why source Antminer parts from LYS Shenzhen

LYS operates in Shenzhen — the world's largest electronics market — with direct supply relationships built over years of trading Bitmain hardware. Three reasons to source from us :

• Genuine parts only — every APW PSU and control board is load-tested before shipping ; passive components (fans, capacitors, MOSFETs) are inspected for batch consistency.
• Bulk pricing and direct invoicing — for repair shops and mining farms managing fleets of 50+ Antminers, our quote-based pricing beats storefront rates and supports dedicated payment terms.
• Worldwide shipping with DDP option for US and EU customers — we handle customs, you receive the goods with all-in landed cost quoted upfront.

Frequently asked questions

Are these original Bitmain parts or aftermarket ?
Both, depending on the SKU. Genuine Bitmain-branded items (APW PSUs, official control boards) are clearly marked. Compatible third-party replacements (generic fans, capacitors, MOSFETs) are noted as "compatible" in the product description.

My Antminer model isn't in your collection — can you still help ?
Yes. Share the part number on the failed component (PSU like APW12-12-3600-V1, control board like Amlogic C76, hashboard chip like BM1398) and we'll source the match from our network.

What's the lead time on bulk orders ?
Lead times depend on the part and quantity. Small orders typically dispatch within a few business days ; larger orders requiring sourcing or aggregation are quoted with a specific timeline when we send the offer.

Do you supply hashboards for repair, or only individual components ?
We supply repair components for hashboards — ASIC chips, MOSFETs, capacitors, temperature ICs, stencils for rework — but we do not sell complete hashboards as standalone units. For full hashboard testing, our test fixture catalogue covers most Bitmain series.
