Professional Z11 / Z15 / Z15PRO Repair Service – Chip-Level Repair, Thermal Maintenance & Hosting Options

With the rising price of Zcash (ZEC), the demand for Z11 and Z15 miner repair continues to grow. At Frontline Hash Service LLC, we specialize in chip-level Z-series miner repair, providing fast, reliable service that restores your equipment to peak performance.
Chip-Level Repair for Z11 / Z15
We focus exclusively on miner hardware repair — not power supplies. Our engineering team handles:
- Chip-level diagnostics and rework
- PIC malfunction repair
- Hashboard dropout / no-temperature / no-hash issues
- Full hashboard testing
- Comprehensive unit maintenance
⚠️ We do not repair PSUs (power supplies).
PSUs are inexpensive and easily replaceable — customers can source new units more cost‑effectively.
Complete Thermal Maintenance
To address common overheating issues with Z11 and Z15 units, we provide full thermal servicing:
- Full thermal paste replacement
- Dust and debris cleaning
- Heatsink and thermal structure optimization
This significantly improves heat dissipation, stability, and miner lifespan.
Miner Resale Assistance
If you no longer wish to operate your equipment, we can assist with miner resale, helping you get a fair market price.
Hosting Options After Repair
Repaired miners can be placed directly into our partner hosting sites, allowing you to resume hashing immediately without searching for a facility or power rate.
