Our Repair Process
To ensure consistent quality, we follow a structured repair process.

First, we carry out detailed fault-finding to identify the root cause at component level.
2. Component Replacement
Next, we replace faulty and worn components using OEM-standard parts to improve reliability.
3. Cleaning & Refurbishment
After that, we clean and refurbish PCBs and modules to remove dust, dirt, and contamination.
4. Testing & Verification
Then, we test each controller using in-house test rigs to simulate real operating conditions.
5. Return with Warranty
Finally, we return your controller with a full 12-month warranty for complete peace of mind.
