AC PCB Repair in Sant Nagar, Delhi

Refix India Repairing Servicesprovides AC PCB repair in Sant Nagar, Delhi (110084), at your doorstep. We repair PCB boards for inverter and non-inverter, split and window ACs. The PCB (printed circuit board) is the main control unit of an AC. It controls the compressor, fan motor, temperature sensor, display, and remote functions.

A faulty PCB can cause problems such as poor or no cooling, the AC not turning on, repeated tripping, fan issues, or error codes. Our technician inspects the PCB at your home, identifies the faulty component, and provides a written repair estimate before starting the work.

Inverter AC PCBs generally cost more to repair than non-inverter boards because they contain more advanced power electronics. Refix India has completed 56,000+ appliance PCB repairs over 15+ years and provides a 30-day service warranty on AC PCB repairs.

Whether you have an inverter or non-inverter AC, our technician can diagnose and repair the control board at your doorstep in Sant Nagar, Burari, Delhi, often on the same day.

What an AC PCB Does — and Why It Fails

The PCB is the decision-maker inside every modern split or window AC. It reads the temperature sensor, decides when the compressor should switch on or off, controls fan speed, communicates with the remote and display, and trips the unit if it senses a fault. When even one component on this board fails, the whole AC can stop responding — even though the compressor and gas are perfectly fine.

Common causes of PCB failure

  • Voltage fluctuations and power surges — Damage relays, transistors, and PCB components.
  • Moisture and humidity — Corrode solder joints, connectors, and electrical contacts.
  • Dust and heat build-up — Overheat components and increase electrical stress.
  • Rodent or insect intrusion — Damages wiring, tracks, and electrical connections.
  • Component ageing — Weakens capacitors, relays, and other PCB components.

Signs your AC PCB Needs Repair

Any one of these can point to a PCB fault — though a couple can also come from a gas or capacitor issue, which is why an on-site inspection is worth doing before assuming it’s the board.

  • AC doesn't switch on at all, even from the panel button
  • Remote or display unresponsive despite the AC having power
  • Fan runs, but the compressor never starts — no real cooling
  • AC starts, then trips or shuts off within minutes
  • Blinking indicator lights or an error code on the display
  • A clicking relay sound on start, but nothing happens

Repair vs. Replace

Component-Level Repair, not a Full Board Swap

Most AC PCB failures come down to one or two specific parts — a relay, a capacitor, a burnt track, or a damaged connector — rather than the entire board. Refix India’s technicians diagnose and repair at the component level, replacing only the part that has actually failed. It’s faster than sourcing a full replacement board, and considerably cheaper.

When full replacement makes sense

Replacing the entire PCB is recommended only when the board is physically burnt, cracked, severely water-damaged, or beyond safe repair. Replacement may also be necessary when an older AC model has an obsolete or unavailable PCB.

Before starting any work, our technician will explain the condition of your AC’s PCB and recommend the most suitable option. The estimate will clearly state whether your AC needs PCB repair or complete PCB replacement.

Frequently Asked Questions

Cost depends mainly on whether the AC is an inverter or non-inverter and whether it’s a component-level repair or a full board replacement. As a general market reference, non-inverter AC PCB repair typically starts around ₹1,500, while inverter AC PCB repair typically starts around ₹4,500, since inverter boards carry more power electronics. Refix India inspects the board first and shares a written quote before starting any work.

Call +91 9711779066 to book AC PCB repair in Sant Nagar, Burari, Delhi. A technician is typically sent to your home the same day, inspects the AC, and shares a written estimate before any repair work begins.

Common signs include the AC not switching on at all, the remote or display becoming unresponsive despite power, the fan running without the compressor starting, the AC tripping or shutting off within minutes of starting, blinking error codes, or a clicking relay sound with no response. These symptoms can also come from a gas or capacitor issue, so an on-site inspection is needed to confirm the PCB is the cause.

Most AC PCB failures come down to one or two failed components, such as a relay, capacitor, connector or a burnt track, rather than the entire board. Component-level repair fixes only the failed part and is faster and cheaper than a full board replacement. Full replacement is usually recommended only when the board is physically burnt, cracked, water-damaged beyond safe repair, or parts are unavailable for a very old model.

Yes. Inverter ACs use a more complex control board with additional power electronics to continuously vary compressor speed, so inverter PCB repair usually costs more and can take a little longer if a part needs sourcing. Non-inverter (fixed-speed) boards are simpler and generally quicker and cheaper to repair. Refix India repairs both types.

15+ years of experience, 100+ trained technicians, 56,000+ completed repairs, a written estimate before any work starts, and a 30-day service warranty on every repair. The technician diagnoses the specific failed component rather than defaulting to a full board swap.

Yes. Every AC PCB repair from Refix India includes a 30-day service warranty covering the workmanship of the repair.

No. Physical damage, liquid or water damage, panel replacement charges, the cost of spare parts, and accessory replacement fall outside the standard PCB repair scope. The technician flags any of these during the on-site inspection before work begins.
