Step-with the Aid of using-Step Guide | How to Test an AC Capacitor
Below is the most secure and maximum broadly used approach for testing an AC capacitor with a multimeter:
Locate the Capacitor
- Identify the capacitor in the outside condenser unit.
- It is often a small cylindrical or oval-shaped tool offering 3 terminals.
Disconnect Power
- Turn off the electricity at the primary breaker and confirm with a voltage tester.
Remove and Discharge the Capacitor
- Carefully detach the wires from the capacitor terminals.
- Utilize an insulated screwdriver to discharge any residual electricity.
Set the Multimeter
- Adjust your virtual multimeter to the Capacitance (µF) setting.
Measure the Capacitance
- Connect the multimeter ends to the capacitor terminals.
- Compare the size to the capacitor`s detailed rating (e.g., 35 µF).
Analyze the Results
- If the size falls within ±5–10% of the rated value, the capacitor is functioning properly.
- If the size is drastically lower, the capacitor is faulty and calls for replacement.
- By adhering to those steps, you may correctly test the AC capacitor in your home.

FAQs
What Is An Ac Capacitor And Why Is It Important?
An AC capacitor is a small electrical part that stores and releases energy to help your air conditioner’s compressor and fan motor start and run properly. Without a working capacitor, your air conditioner may fail to start, blow weak air, or stop cooling your home altogether.
How Can I Tell If My Ac Capacitor Is Bad?
You can usually tell your AC capacitor is bad if your unit won’t start, makes a humming sound, blows warm air, or the outdoor fan does not spin. If your air conditioner keeps shutting off or takes longer to cool your home, it’s also a sign that the capacitor may be failing.
What Tools Are Needed To Test An Ac Capacitor?
To test an AC capacitor, you need a digital multimeter that can measure capacitance, an insulated screwdriver to safely discharge power, and protective gloves for safety. These tools allow you to check whether your capacitor is holding the correct electrical charge.
How Do You Safely Test An Ac Capacitor With A Multimeter?
First, turn off the power to your air conditioner from the main breaker. Then, use an insulated screwdriver to discharge any remaining power from the capacitor. Remove the capacitor from its mounting and connect the multimeter probes to its terminals. Set your multimeter to the capacitance mode and check the reading. If the reading is more than 10 percent lower than the value printed on the capacitor, it’s time to replace it.
