AC PCB Repair in Kadapa: Cost, Symptoms and When to Replace
The PCB (the green circuit board inside the indoor unit) is the brain of your AC. When it fails, weird things happen: random restarts, dead display, frozen fan speed, no response to the remote. The good news is that most PCB faults are repairable at component level for under ₹3,500, not a full replacement.
PCB symptoms checklist
- Display dead but power is reaching the AC
- Display works but remote does nothing (or only some buttons)
- AC turns on by itself or restarts randomly
- Fan speed stuck on one setting
- Swing motor or louvers stop moving
- Cooling mode changes on its own
- Burnt plastic smell from indoor unit
- Beep on every key press but no action
Repair vs replacement, how technicians decide
A good technician opens the PCB and inspects it under a magnifier. Localized burn (one or two components blackened) is repairable. Multiple burnt tracks, cracked board, or water damage across the board means replacement. We tell you upfront which one applies and quote both options.

Why Kadapa PCBs fail more often
Two reasons specific to Kadapa: (1) voltage fluctuations are common, peak summer load drops voltage to 180V or lower and induction motors elsewhere cause spikes back up. Cheap or absent stabilizers leave the PCB exposed. (2) Monsoon thunderstorms send surges down the line. A good 4 kVA servo stabilizer with input range 130V to 280V solves both.
How to prevent the next PCB failure
- Install a quality servo stabilizer (not a cheap ₹800 relay type)
- Get annual deep cleaning so the indoor coil doesn't drip on the PCB
- Keep food, water and pet bowls away from the indoor unit
- Switch off the AC at the wall during heavy thunderstorms
- Seal small gaps around indoor unit pipes (rats love chewing PCB tracks)

Frequently Asked Questions
How do I know if my AC PCB is faulty?+
Classic signs: display flickers or stays dead, AC restarts on its own, no response to remote or only some buttons work, burnt smell from indoor unit, fan speed won't change, swing motor doesn't move. Often one or two of these together.
Is PCB repair cheaper than replacement?+
Yes. Component-level repair (replacing a burnt capacitor, IC, transistor or fuse on the existing PCB) costs ₹1,500 to ₹3,500. Full board replacement costs ₹3,500 to ₹6,500. We always try repair first if the board damage is localized.
What causes AC PCB failure in Kadapa?+
Voltage spikes (most common), water seepage from drain leakage onto the board, rat bite on PCB tracks, lightning surges during monsoon, and general aging after 5+ years of use.
Does a stabilizer prevent PCB damage?+
Yes, a good servo stabilizer (not a cheap relay stabilizer) absolutely prevents most PCB damage. Spending ₹3,500 once saves ₹3,500+ on PCB replacements every 2 to 3 years.
Should I repair the PCB or buy a new AC?+
If the AC is under 6 years old and otherwise healthy, repair the PCB. If it is 10+ years old with R22 gas, a new inverter AC makes more sense. Inverter AC PCBs are more expensive (₹5,000 to ₹9,000) but last longer when paired with a stabilizer.
