Why ASIC miners need repairs
A Bitcoin ASIC runs flat out, around the clock. Its fans spin continuously, its power supply converts kilowatts of electricity every hour, and its chips run hot. Over time, heat cycling, dust and ordinary wear cause parts to fail. When that happens, a miner may hash at a reduced rate, drop offline, or stop booting altogether.
Most failures come down to a single part: a worn fan, a tired power supply, a failed control board or a faulty hashboard. Replacing that part usually brings the miner back to full hashrate for a fraction of the cost of a new machine.
Why on-site repairs save hashrate
Every day a miner sits in a shipping box is a day of lost hashrate. Because our technicians work inside the facility, faults are diagnosed and fixed where the miner already lives. Most repairs are performed in-house without sending miners outside, and the miner goes straight back into its rack once it passes testing.
We also monitor pool status, so we often spot an offline miner before you do and can start diagnosing it right away.
Common symptoms and what they usually mean
A miner hashing well below its rated speed often points to a hashboard or chip fault. A miner that will not boot usually points to the power supply or control board. A miner that runs hot, throttles or shuts down is often a fan problem or an airflow issue. These are general patterns rather than a diagnosis, which is why every repair starts with testing on site.
The parts we replace
Cooling fans are the most common replacement on any air-cooled miner, because they run continuously at high speed. Power supplies are next, followed by control boards, hashboards, cables, connectors and temperature sensors. Our filtered air cooling, with 156 summer/winter air filtration, keeps dust levels down, which helps every one of these parts last longer.
How our repair process works
First, a technician diagnoses the miner in-house using industry testers to find the failed part. Next, we advise you on the repair cost before any work goes ahead. Once you approve, we repair the fault or replace the part, test the miner, re-rack it and point it back at your pool.
Repair pricing
For hosted miners, our hosting plans usually include the labour and you only pay for the spare parts. If a miner goes offline for an extended period and it is not bootable, you may be entitled to compensation for unused power, credited to your hosting bill.
If your miners are not hosted with us, contact us with the model and the fault. Shipping and customs to our facility are the customer’s responsibility, and we quote after diagnostics. Many clients choose to keep their repaired miners hosted with us afterwards, starting with bring your own miner + hosting.
Keeping miners healthy between repairs
Clean, cool air is the best preventive maintenance a miner can get. Steady intake temperatures, filtered air and organised airflow reduce strain on fans and chips alike. That is why our facility is built around filtered air cooling, with 8 intake ducts and 4 exhausts, and why we host current-generation air-cooled miners. Learn more about hosting with us.
