How to Troubleshoot Common Issues with the Fluminer L2?
Encountering issues? Here’s how to diagnose and fix common problems.
Common issues include network connectivity, abnormal hash rates, and power failures, which can often be resolved with simple checks.
Miner Unable to Connect to Network
- Check the network connection or restart the router.
Miner Overheating
- Ensure the device is placed in a well-ventilated area and clean the dust from the air vents.
- If the device has been running for over 1 year, replace the thermal interface material of the heatsink.
Miner Status Not Updating on the Pool Side
- Verify that the mining pool account is correct.
- After starting the device, wait for approximately 10 minutes for confirmation.
Usage Precautions
The recommended operating temperature range for the speaker is 18°C to 45°C. Excessively low temperatures may reduce sensitivity, while high temperatures can damage components or cause premature aging. Avoid direct sunlight and keep away from heat sources.
Always turn the volume knob to the minimum level before switching the speaker power on or off.
Place the speaker separately from other equipment, as stacking may cause sympathetic resonance.
For optimal sound quality, minimize interference. Avoid sharing the same power circuit with other household appliances or computers to prevent cable-induced noise degradation.
Avoid contact with chemicals such as benzene or thinners.
Keep away from strong magnetic and electric fields.
Do not disassemble, repair, or modify the unit yourself.

What is the Repair Process for the Fluminer L2？
Is your Fluminer L2 dead? Follow my exact step-by-step journey through official repairs – from first contact to getting back mining.
Day 1: The Dreaded “ERROR 404” Screen (My Miner Was Bricked)
At 3 AM, my Fluminer L2 displayed a solid red “ERROR 404” light. No amount of reboots helped. Here’s exactly what I did:
1️⃣ Contacting Support (The Right Way)
- Went to Fluminer.com/support (NOT third-party forums)
- Prepared my miner’s serial number + purchase invoice before starting
Pro Tip: Take a video of the error light first – support asked for visual proof immediately.
Day 2: The Diagnostic Dance (What They Actually Check)
The support agent didn’t just take my word for it. We went through:
2️⃣ The 5-Point Fault Confirmation:
- Hardware Test: Had me check all cable connections with photos
- Firmware Check: tell support about the firwware version
- Pool Test: Temporarily switched to their test pool (ruled out pool issues)
- Power Diagnostic: Sent my voltage meter readings
- Log Extraction: Guided me to download the crash logs
Shocker: My logs showed “PSU Overload Protection Triggered” – a known issue with v2.1.7-for example!
Day 3: Packing for the Repair Journey (Don’t Mess This Up!)
3️⃣ Shipping Prep Checklist:
- ✂️ Removed all cables (but kept original packaging)
- 📦 Used the original foam inserts (voids warranty if missing)
- 📝 Printed RMA# FL2024-XXXX on the box (critical!)
- 🚚 Chose DHL Express (their recommended carrier)
Days 4-5: What Actually Happens During Repairs
The support agent shared rare behind-the-scenes details:
4️⃣ The Repair Process:
- Bench Testing: Hooked to their diagnostic rig
- Component Swap: Replaced my faulty power module (common issue)
- 48-Hour Burn-In: Ran at 100% load to verify stability
- Firmware Downgrade: Rolled back to stable firmware
Fun Fact: They test with Litecoin testnet pools to avoid real coin mining during repairs.
Day 7: The Homecoming (It’s Alive!)
First 24H Stats Post-Repair:
✔ 1.2 Gh/s stable (vs previous 0.2 Gh/s fluctuations)
✔ 72°C max temp (was hitting 89°C before)
✔ 0 rejected shares (down from 3.2%)
3 Critical Lessons Learned
- Video Evidence is King: My 30-second error video sped up approval by 3 days
- Original Packaging Matters: Almost voided my warranty by tossing the foam
- Burn-In Period is Crucial: They caught a secondary fault during 48H testing
