Whatsminer & MicroBT Replacement Parts and Repair Components

Whatsminer ASIC miners — manufactured by Shenzhen MicroBT Electronics Technology — are deployed in mining operations worldwide for their consistent hashing performance and robust mechanical design. When a board fails, a power supply dies, or a fan seizes, having direct access to genuine Whatsminer replacement parts becomes critical to keep your hash rate online. Our Whatsminer parts catalogue covers every generation from the legacy M20 series to the current M60/M66 air-cooled and M63 hydro miners, sourced through Shenzhen-based supply channels with quality control at every step.

Common Whatsminer failures and the parts you need

When a Whatsminer M30S, M50, or M60 stops producing hash rate, the issue almost always traces back to one of four subsystems. Our catalogue covers each:

• Control boards (CB4 V10, CB5, CB6 V10, H6, H3 series) — when the miner won't boot or the IP won't appear, the control board is the first suspect.
• Power Supply Units (P221B, P221C, P232B, P231B series for air-cooled ; P566Z and P564Z for hydro) — failed start-up, fluctuating voltage, or fan-only behaviour usually means PSU replacement.
• Hashboards and ASIC chips — when one hashboard goes down with X errors or freezes at 0 hash, individual chip replacement, hashboard repair, or testing with a fixture is the path forward.
• Cooling fans and adapters — 12cm 4-pin for older series, 14cm 6-pin for M30+/M50+/M60+ generations ; seized fans cause thermal shutdowns within minutes.

Why source Whatsminer parts from LYS Shenzhen

LYS is based in Shenzhen — the world's largest electronics market — with direct supply relationships built over years of trading in mining hardware. Three things you get when ordering from us :

• Genuine parts only — every 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+ miners, 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, no surprises at delivery.

Frequently asked questions

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

My Whatsminer model isn't in your collection — can you still help ?
Yes. Share the part number on the failed component (PSU P/N like P221B-GB-12-3300-C, control board model like CB6 V10, fan model like GH14038BZW-1) 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 offer technical support to diagnose which part I need ?
Yes. Send a description of the symptoms — error logs, fan-only mode, no IP, hashrate drop, frozen hashboard, etc. — and we'll guide you to the most likely failure point and the right replacement.

Can I order spare parts for older Whatsminer models like M20 or M21 ?
Yes. We stock parts for legacy M20/M21 series alongside current M50/M60 generations. Some older parts have longer sourcing times if they're EOL with MicroBT, but our aftermarket channels keep most replacements available.
