In this guide, we’ll take you through the steps on how to test AC compressor capacitor. Testing an AC compressor capacitor is an important maintenance task that can save you from a potential AC breakdown. Why, you ask? Well, the capacitor is the part of your AC that stores and supplies energy to the compressor. If it’s not working right, your AC won’t cool your space effectively.
Understanding the Function of a Compressor Capacitor – How to Test AC Compressor Capacitor
Imagine your AC unit as a track team. The capacitor is like the runner in the relay race who passes the baton (energy) to the next runner (compressor). Without a good hand-off, the race is lost, right? Same concept with the capacitor and compressor.

So, the compressor capacitor’s main job is to store electrical energy and supply it to the compressor when the AC unit starts up. If it’s faulty, it can’t do its job, which affects the performance of your AC. It’s like trying to start a race with no baton – not going to end well, is it?
Identifying Signs of a Faulty Compressor Capacitor
Like a runner with a limp, a faulty capacitor shows signs that something’s wrong. You might notice your AC isn’t cooling properly, it’s making strange noises, or it’s not starting up at all. These are your cues that the capacitor might be failing. Remember, the sooner you catch it, the better!

Before we dive into the how-to, let’s talk about what you’ll need and the safety measures you should take. We don’t want you getting zapped, after all!
Gathering Necessary Tools – How to Test AC Compressor Capacitor
Before any great adventure, you need your gear. Testing a capacitor is no exception. You’ll need a multimeter (that’s your trusty map), screwdrivers (your climbing gear), and safety gloves and goggles (your helmet and shield). Sounds like quite the quest, doesn’t it?
Safety Measures Before Testing
Capacitors can store a lot of energy, which can be dangerous if not handled properly. To keep safe, always turn off and unplug your AC before starting. And don’t forget those gloves and goggles – they’re your best friends in this adventure.

Alright, now that we’re prepped and ready, let’s get to the main event – testing the compressor capacitor.
Accessing the Compressor Capacitor
Your first step is to locate and access the capacitor. Think of it as the hidden treasure in this quest. It’s usually found in the compressor area of your AC unit, inside a metal box. Unscrew the box and you’ll find your capacitor.
Discharging the Capacitor – How to Test AC Compressor Capacitor
Now, we need to discharge the capacitor. This is like defusing a bomb – it gets rid of any dangerous stored energy. To do this, use a metal tool like a screwdriver (with an insulated handle!) to bridge the two terminals on the capacitor.
Testing the Compressor Capacitor with a Multimeter
Here’s where your multimeter comes in. Set it to read capacitance (μF), and attach the leads to the capacitor’s terminals. It’s like taking the pulse of your capacitor.
Interpreting the Test Results – How to Test AC Compressor Capacitor
So, what do these numbers on the multimeter mean? Let’s break it down.
Understanding Multimeter Readings – How to Test AC Compressor Capacitor
The reading on your multimeter represents the capacitance value of your capacitor. If it’s within 6% of the value stated on the capacitor, it’s in good shape. If it’s not, you’ve got a faulty capacitor on your hands.
What to Do If the Capacitor Is Faulty
If your capacitor is faulty, don’t fret. It’s like replacing a worn-out baton. You can purchase a new capacitor online or at a local store and replace it yourself, or call in a pro to do it. Either way, you’re back in the race!
