What happens when an AC capacitor fails

An air conditioner (AC) capacitor is a crucial component that powers the compressor, fans, and other essential parts of your cooling system. When it fails, your AC may stop functioning entirely or operate inefficiently. In this article, we’ll dive into what happens when an AC capacitor fails, the symptoms to watch for, and how to address the issue effectively.

What Is an AC Capacitor?

An AC capacitor stores and supplies the electrical energy needed to run your air conditioner’s motors. It provides the initial jolt of power required to start the compressor and fan and keeps them running smoothly. Capacitors are categorized into two main types:

1. Start Capacitors: Supply the initial power needed to start the AC.
2. Run Capacitors: Provide consistent power to maintain motor operation.

What Happens When an AC Capacitor Fails?

When an AC capacitor fails, the electrical supply to your air conditioner is disrupted, leading to:

• Failure to Start: The compressor or fan may not start at all.
• Intermittent Operation: The AC may turn on and off irregularly.
• Increased Energy Consumption: A struggling capacitor can cause the system to work harder, leading to higher energy bills.
• Overheating: Motors may overheat due to insufficient power, potentially causing further damage.

Symptoms of a Failing AC Capacitor

Recognizing the signs of a failing capacitor can save you from costly repairs. Look out for these symptoms:

1. AC Not Cooling: Insufficient cooling is a common sign of capacitor failure.
2. Humming Noise: A buzzing or humming sound may indicate the capacitor is trying to work but failing.
3. Fan Not Spinning: If the fan isn’t rotating, the capacitor might not be delivering power.
4. Frequent Cycling: The AC turns on and off more often than usual.
5. AC Won’t Turn On: A completely dead capacitor will prevent the AC from starting.
6. Burning Smell: A damaged capacitor may emit a burning odor.

Causes of Capacitor Failure

Several factors can lead to capacitor failure:

• Age: Capacitors typically last 10-15 years, depending on usage.
• Power Surges: Voltage spikes can damage the capacitor.
• Heat Exposure: Excessive heat can reduce its lifespan.
• Poor Quality: Substandard capacitors may fail prematurely.
• Wear and Tear: Regular use can lead to gradual degradation.

AC Brands with Low Capacitor Failure Rates in India

When choosing an AC, consider brands known for their durability and reliable components. In India, brands like Daikin, Hitachi, and Blue Star are reputed for using high-quality capacitors with low failure rates. Their robust manufacturing standards ensure long-lasting performance and fewer breakdowns.
