Repair vs Replace: PCB Decision Guide
Not every dead PCB needs replacement. Here is when repair makes sense and when it is a waste of money.
Try Repair First (₹1,500–₹3,000)
- Burnt capacitor or resistor — easy component swap
- Corroded connector pins — clean and re-solder
- Dry solder joints — re-flow with hot air station
- Blown fuse — replace with correct rating
- Single visible burn mark in an isolated area
- Non-inverter PCB with simple relay logic
Replace Immediately
- Burnt IC chip or microcontroller — not repairable
- Multiple burn marks across the board
- Water damage or corrosion on multiple traces
- Inverter PCB with IGBT module failure
- Previous repair failed within 6 months
- Board is discontinued — no spares available
How to Protect Your PCB from Future Damage
PCB failures are 80% preventable. Here is what we recommend after 500+ service calls.
Use a quality stabilizer
Voltage fluctuations are the #1 PCB killer. A stabilizer with 180V–260V range and surge protection costs ₹2,000–₹4,000 — far cheaper than a ₹8,000 PCB replacement.
Turn off AC before power cuts
When power goes out, switch off the AC at the MCB. The voltage spike when power returns burns capacitors and ICs. Use the stabilizer's time-delay feature.
Keep indoor unit dry
In coastal and high-humidity areas, moisture corrodes PCB traces. Run a dehumidifier or use the AC's dry mode for 30 minutes daily. Seal any gaps in the casing.
Seal against insects
Lizards and cockroaches short-circuit PCB traces. Use mesh covers on vents and seal gaps around pipes entering the indoor unit.
Avoid extreme temperature cycles
Running the AC at 16°C continuously then turning it off causes rapid thermal expansion/contraction of solder joints. Set 24–26°C for normal use.
Service every 6 months
During service, ask the technician to inspect the PCB for dust buildup, loose connections, and capacitor bulging. Early detection prevents catastrophic failure.
If your AC PCB keeps failing, voltage protection is the likely cause. See our top stabilizer picks for inverter ACs.

AC PCB FAQs
Common questions about AC control board replacement in India
How much does an AC PCB cost in India?
AC PCB replacement costs ₹3,000–₹12,000 in India. Non-inverter AC PCBs cost ₹3,000–₹5,000. Inverter AC PCBs cost ₹5,000–₹12,000 depending on brand and features. Basic 1.5 ton PCBs from local brands cost ₹3,000–₹5,000. Premium brand PCBs with WiFi and advanced sensors cost ₹7,000–₹12,000. Labor for diagnosis and replacement adds ₹800–₹1,500.
Can AC PCB be repaired instead of replaced?
Yes, minor PCB faults can be repaired for ₹1,500–₹3,000. Repairable issues include: burnt capacitors or resistors, corroded connector pins, dry solder joints, and blown fuses. However, if the PCB has: burnt IC chips, damaged microcontroller, multiple layer damage, or water ingress corrosion — replacement is the only reliable option. Repaired PCBs have a 30–50% chance of failing again within 6 months. For inverter ACs under warranty, always demand OEM replacement.
Why do inverter AC PCBs cost more?
Inverter PCBs contain a complex microcontroller, IGBT power modules, current sensors, and firmware that controls compressor speed in real-time. They handle high-voltage DC conversion and precise frequency modulation. Non-inverter PCBs are simple relay boards that just switch power on/off. The additional components and programming make inverter PCBs 2–3x more expensive. They also require specialized diagnostic tools and trained technicians.
How do I know if my AC PCB is faulty?
Common PCB failure symptoms: 1) The indoor unit shows blinking LEDs or error codes that do not clear after reset. 2) The compressor starts but shuts off within seconds (overload protection triggered by PCB fault). 3) The remote works but the AC does not respond to any command. 4) Burnt smell from the indoor unit. 5) Random shutdowns or mode changes without input. Count the LED blinks and search online for your brand's error code chart — each brand uses different blink patterns.
Is PCB covered under AC warranty?
Most brands cover the PCB for 1–5 years depending on the model tier. Premium inverter ACs often include 3–5 year PCB warranties. However, warranty coverage requires: purchase from authorized dealer, installation by brand-authorized technician, registration within 30 days, and no voltage damage. Voltage surge damage is often excluded unless a stabilizer was used. Keep your invoice and installation certificate — brands reject 40% of PCB warranty claims due to missing documentation.
What causes AC PCB failure?
The top causes in India: 1) Voltage surges and fluctuations — the #1 killer of PCBs. A quality stabilizer with surge protection prevents 80% of PCB failures. 2) Power outages with sudden restoration — the voltage spike when power returns burns components. 3) Moisture and humidity — coastal and high-humidity areas see 3x more PCB corrosion. 4) Poor ventilation around the indoor unit — heat buildup degrades capacitors. 5) Insects and lizards — they short-circuit PCB traces. Use a stabilizer, keep the area dry, and seal any gaps in the indoor unit casing.
How long does PCB replacement take?
Diagnosis takes 30–60 minutes. A technician tests voltage inputs, checks error codes, and inspects the board for visible damage. Replacement takes 1–2 hours including: removing the old board, installing and configuring the new board, reconnecting all sensors and wiring, and testing all modes. For inverter PCBs, some brands require firmware programming which adds 30 minutes. Total service time is 2–3 hours. Same-day service is possible in metro cities if the PCB is in stock.
Should I buy a PCB online and install it myself?
Only if you have electrical training and the exact part number. PCBs are model-specific — even within the same brand, different production batches use different PCB revisions. Installing the wrong PCB can damage the compressor, void warranty, and create fire hazards. For inverter ACs, the PCB must be paired with the compressor via firmware. Always have a certified technician diagnose the fault, verify the exact part number, and perform the installation. Online PCBs often have no warranty and may be refurbished or counterfeit.
