Cleaning and Dusting Your ANTMINER: Step-by-Step Guide

Start with safety and logs

Power down before opening a miner, label cables before moving boards, and capture logs before repeated reboots erase useful evidence. Record model, firmware, pool, uptime, fan speed, temperature, reject rate, chain count, and the exact error text.

Confirm the fault class

Separate configuration faults from hardware faults first. Pool errors, DNS failures, bad worker names, overheating, weak power, fan faults, and missing hashboards can look similar from the dashboard but require different fixes.

Document the test path

Change one variable at a time and keep the before/after result. Note cable swaps, PSU swaps, firmware changes, pool changes, fan replacements, ambient temperature, and whether the fault follows a hashboard, control board, network, or power source.

When to escalate

Escalate to professional repair when there is a burned smell, melted connector, breaker trip, corrosion, repeated hashboard loss, liquid exposure, or a board-level fault that returns after a basic cable, power, firmware, and airflow check.

After the fix

Run the miner long enough to confirm stable accepted hashrate, fan behavior, chip temperature, reject rate, and pool-side reporting. A dashboard that looks normal for five minutes is not enough evidence for a recurring power, heat, or hashboard fault.

Regular maintenance of your ANTMINER is crucial to ensure optimal performance. Dust and debris can accumulate on the casing and hash board, potentially affecting the heat dissipation and overall functioning of the miners. Here’s a step-by-step guide on how and when to clean your ANTMINER.

When to Clean the ANTMINER

  1. When the casing of the miners appears dusty.
  2. If the miners aren’t running properly due to dust accumulation or other debris attaching to the hash board, impacting heat dissipation.
  3. During your routine inspection of the miner. To maintain optimal performance, we recommend cleaning the dust off your miner at least once a month.

IMPORTANT: Always shut down the miners before cleaning.

Equipment Needed for Cleaning

  • Air Compressor
  • Air Gun (Ensure the air pressure range is 0.7 +/- 0.05 MPa)

Cleaning Procedure

Follow these steps to thoroughly clean and dust your ANTMINER:

  1. Blow the front and rear fans: Use the air gun to gently blow the front and rear fans twice.

    Blow Front and Rear Fans

  2. Blow each gap: Position the air gun close to the fan, ensuring it doesn’t touch the grille or fan blades to avoid causing any damage. Blow air into every gap for 2-3 seconds. Repeat this process 2 to 3 times.

    Blow Each Gap

  3. Deal with stubborn dust: If you’re unable to blow out the dust due to high humidity (which can cause dust to stick), remove the fan and brush out the stubborn dust manually.

    Cleaning Stubborn Dust

Following these steps will help to ensure your ANTMINER remains clean and efficient, ultimately enhancing its lifespan and performance. Regular maintenance should be a key part of your mining operations to prevent any potential issues and maintain high productivity.
