Avalon Crypto Miner replacement parts and repair tools

Avalon & Canaan Replacement Parts and Repair Components

Avalon ASIC miners — manufactured by Canaan Creative — are widely deployed for Bitcoin mining thanks to their robust mechanical design and competitive efficiency across the A1066, A1166, A1246, A1266, A1346, A1366, A1446, A1466, and the latest A1566 generations. When a hashboard fails, a PSU stops delivering stable voltage, or a control board freezes, your hash rate drops and the unit produces nothing. Our Avalon parts catalogue covers every air-cooled and immersion model from the legacy 1066 series through the current Avalon Made A14 and A15 line-up, sourced through Shenzhen-based supply channels with consistent QC.

Common Avalon failures and the parts you need

When an Avalon 1246, 1366, or 1466 stops producing hash rate, the issue usually traces to one of four subsystems. Our catalogue covers each :

• Control boards — Avalon control board for 1066 Pro / 1166 Pro / 1126 / 1246 / 1126 Pro / 1248 / 1266 ; updated control board for 1346 / 1366 / 1446 / 1466 / 1566. When the miner won't boot or shows persistent errors, the control board is the most common cause.
• Power Supply Units (Avalon 3300-03 Plus for A1066 / A1166 / A1246 ; updated Avalon PSU series for A1346 / A1366 / A1466) — failed start-up, fluctuating voltage, or fan-only behaviour usually indicates a PSU fault.
• Hashboards and ASIC chips — A3200, A3201, A3202, A3203, A3204 series chips depending on generation. Capacitors, boost modules (17.5V for 1166 / 1246), conductive copper sheets, and temperature ICs for hashboard repair.
• Cooling fans and adapters — 4-pin square or 6-pin linear configurations, plus PSU cooling fans (40mm / 60mm) and fan speed simulators for immersion-cooled Avalon setups.

Why source Avalon parts from LYS Shenzhen

LYS is based 15 minutes from Huaqiangbei — the world's largest electronics market — with direct supply relationships across the Canaan and Avalon aftermarket. Three reasons to order from us :

• Genuine parts only — every Avalon PSU and control board is load-tested before shipping ; ASIC chips and passive components are inspected for batch consistency.
• Bulk pricing and direct invoicing — for repair shops and mining farms managing fleets of 50+ Avalon miners, our quote-based pricing 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 upfront.

Frequently asked questions

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

My Avalon model isn't in your collection — can you still help ?
Yes. Share the part number on the failed component (PSU model, control board version, hashboard chip such as A3203) 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 are quoted with a specific timeline when we send the offer.

Do you stock parts for older Avalon models like 821 or 1066 ?
Yes. We stock parts for legacy A8 and A10 series alongside current A14 / A15 generations. Some older parts have longer sourcing times but our aftermarket channels keep most replacements available.

Can you supply Avalon test fixtures for repair labs ?
Yes. Our test fixture catalogue includes multifunction hashboard testers for A320x and dedicated test boards for chip-level scanning, useful for in-house repair teams diagnosing batches of faulty hashboards.
