🔬 Our Component-Level Repair & Testing Workflow
How every faulty PCB is diagnosed, restored, and calibrated inside our laboratory:
Checking switching DC voltages (3.3V, 5V, 12V, 15V) to protect main MCU processor.
Desoldering burnt power transistors; installing OEM modules with high-temp heat paste.
Oscilloscope testing of serial communication wave, replacing degraded optocouplers.
Run under real compressor & fan motor load on our test rig before return courier.
⚡ Common Faults & Symptoms Restored by Our Engineers:
We repair the following component failures with a 90-day warranty:
Ceiling Cassette & Ductable Inverter AC Electronic Control Board Restoration
Cassette and ducted air conditioners operate in demanding ceiling spaces exposed to humidity and high ambient heat. Common failures include water lift pump driver triacs, float switch interlocks, and 4-way swing louver driver ICs. We rebuild and conformal-coat all circuit tracks for long-lasting reliability.
