Overview
About Our PCB Repair Service
Modern inverter and split AC units rely on printed circuit boards to manage compressor speed, sensors, remote signals, and safety cutoffs. Power surges during Tamil Nadu thunderstorms, voltage fluctuations common in older Trichy neighbourhoods, or moisture ingress after monsoon can damage these boards—leaving your AC dead, beeping, or stuck on error codes.
Sri Ramanas Air Conditioners offers component-level PCB diagnosis and repair where economically viable, and supplies compatible replacement boards when repair is not practical. We test relay outputs, capacitors, fuse links, and sensor inputs before recommending the most cost-effective path.
Replacing an entire AC because of a PCB fault is rarely necessary. Our technicians service boards for Daikin, LG, Samsung, Voltas, Blue Star, and other brands commonly installed across Tiruchirappalli.

Our Process
How It Works
Four clear steps from booking to a cool, tested unit.
Fault Code Reading
We record display codes, test input voltage, and verify remote and sensor signals to isolate PCB versus wiring faults.
Board Removal & Inspection
The control board is removed and inspected under magnification for burnt components, blown fuses, or corroded traces.
Repair or Replace
Faulty relays, capacitors, or ICs are replaced at component level when possible. Otherwise a compatible new board is fitted.
System Calibration
Reinstalled board is tested with full cooling cycle. Sensor readings and compressor response are verified before handover.
