AC Capacitor Burnt? How to Identify and Replace It (Bangalore Guide)

If your AC is humming but not cooling, the compressor capacitor is the most common culprit. Across 25 years of supplying spare parts in Bengaluru, capacitor failure is something we see at least 5–10 times every summer week. Here’s how to spot it and what to buy.

Signs of a Burnt AC Capacitor

• AC humming but compressor not starting — classic symptom
• Capacitor body looks bulged or oily — replace immediately
• Fan motor not running even though indoor unit is on — could be fan capacitor
• Trips your MCB when AC turns on — capacitor short

Which Capacitor Do You Need?

AC capacitors are rated in MFD (microfarads) and voltage. The most common ratings for split ACs in Bengaluru are:

• 30 MFD / 440V — 1 ton split ACs (LG, Samsung, Voltas, Bluestar)
• 35-40 MFD / 440V — 1.5 ton split ACs
• 50-55 MFD / 440V — 2 ton split ACs
• 5 MFD / 440V — fan capacitor (running)

Read the rating off your existing capacitor or send us a photo of the nameplate on WhatsApp at +91 78928 43300 and we’ll identify the correct replacement.

Genuine vs Duplicate Capacitors

This is where most people lose money. A duplicate 35 MFD capacitor costs ₹120 in the grey market and a genuine one costs ₹380–₹450. The duplicate typically lasts 3–6 months before failing again — and the second time it can take the compressor down with it (a ₹15,000 mistake).

We stock genuine running capacitors from Epcos, Havells, Bharti and brand-OEM stock for all major AC brands. Buy once, replace every 5–7 years — not every monsoon.

Need a Technician for Installation?

Capacitors carry residual charge even when unplugged — never touch the terminals directly. We supply the part; we strongly recommend a qualified AC technician install it. We work with several trusted technicians across Bengaluru — happy to refer one in your area.
