Overview of Refrigerator Compressors
Let’s kick off by breaking down what a refrigerator compressor does. You could say it’s like the fridge’s heart, pumping refrigerant through the system to keep everything nice and cool. If the compressor goes haywire, the rest of the fridge might struggle, too.
Role and Importance of Compressors in Refrigeration
A compressor works by pressurizing refrigerant and circulating it around your fridge. Imagine it as a high-powered relay runner, carrying the baton (in this case, the refrigerant) throughout the system to ensure everything stays chilled.
Signs of a Possible Compressor Problem
Not sure if your compressor is having trouble? A fridge that’s not cooling properly, strange noises, or even your energy bill skyrocketing can be telltale signs. Think of these as your fridge sending you an SOS.
The Preliminaries: Safety and Preparation
Before we show you how to check refrigerator compressor, you need to adhere to safety precautions. In this section, we’ll also show you certain things you need to get ready before the main task.
Importance of Safety
Before we start poking around, remember, safety first. You wouldn’t enter a lion’s den without a plan, would you? So, we’re going to ensure we’re well prepared.
Turning Off and Unplugging the Refrigerator
First things first, turn off and unplug your refrigerator. It’s not just about not getting a shock; it’s about making sure you’re safe and sound throughout the process.
Using Appropriate Safety Gear
Donning some safety gear is also crucial. You’re not preparing for a fashion show, but protective gloves and eyewear are a must. Better safe than sorry, right?
Gathering Necessary Tools
Next up, you’ll need to assemble your tools. You wouldn’t enter a jungle without a map, would you? A multimeter, screwdriver, protective gloves, and eyewear should be on your checklist.
Multimeter
A multimeter is like your compass here. It’s going to help us test the motor and relay to see if they’re working as they should.
Screwdriver
You’ll also need a screwdriver. It’s not just for show – you’ll use it to remove the back of the refrigerator and access the compressor.
Protective Gloves and Eyewear
Remember we mentioned safety? Here’s where your protective gloves and eyewear come in handy. Like a knight’s armor, they’ll protect you during the operation.
Step-by-Step Guide on How to Check Refrigerator Compressor
Alright, ready for the adventure? This section will be your map, leading you through the steps on how to check refrigerator compressor. Let’s roll up our sleeves and dive in, shall we?
Locating the Compressor
It’s time to find the compressor. Think of it as a treasure hunt, except your treasure is this key component of your refrigerator.
Unplugging and Moving the Refrigerator
Remember, the first rule of our adventure: safety. Unplug the refrigerator and carefully move it to access the back. Imagine you’re handling a delicate artifact – be gentle and careful.
Accessing the Back of the Refrigerator
The back panel is your gateway to the compressor. Use your trusty screwdriver, and it’ll come off as smoothly as opening a book.
Checking the Compressor for Noise
Noise is one telltale sign that something’s up with your compressor. It’s like your refrigerator speaking to you, and we’re going to interpret what it’s saying.
Identifying Normal and Abnormal Compressor Sounds
A slight hum from the compressor is normal. It’s like a purr, signaling that everything’s alright. But, a loud buzzing or clicking? That’s a cry for help.
Steps to Follow If Your Compressor is Noisy
If you hear a strange noise emanating from your refrigerator, it’s time for a little detective work. Begin by noting the type of sound – is it a hum, a buzz, or a clicking noise? If it’s louder than your usual refrigerator hum, there might be a problem. Firstly, check the fan. A faulty fan can cause noise and also strain the compressor. If the fan is fine, it’s a strong indication that the compressor needs attention.
Testing the Compressor Motor with a Multimeter
Now, we’ll use our multimeter, which is like a detective, helping us decipher the mysteries of the compressor motor.
Accessing the Compressor Motor
The compressor motor is like the engine room of a ship, hidden away but pivotal. We’ll need to reach it to test it out.
Using the Multimeter to Test for Continuity
Once you’ve established that your compressor could be the culprit, it’s time to use your multimeter. Begin by setting your multimeter to the lowest setting for Ohms of resistance (usually a 200 Ω setting). You’re now ready to check the compressor motor for continuity, which essentially means checking if the electric circuit in your compressor motor is working correctly. Locate the three terminals on the compressor (they’ll be marked as S, R, and C for Start, Run, and Common), and test for continuity between these points.
Interpreting the Multimeter Readings
Now comes the time to understand what your multimeter is trying to tell you. When you measure continuity between S and R, S and C, and R and C, you should get a resistance reading. The exact reading can vary based on the compressor, but generally, the resistance between S and R added to the resistance between S and C should equal the resistance between R and C. If it doesn’t, or if any of these show no continuity (a reading of infinity), it’s likely your compressor motor is faulty.
Checking the Compressor’s Start Relay
The start relay is your compressor’s buddy, helping it get started. If it’s faulty, your compressor might struggle too.
Locating and Removing the Start Relay
The start relay is the small device attached to the side of your compressor. To locate it, you’ll have to remove the back panel of your refrigerator and locate the compressor. The start relay will be plugged into the compressor. To remove it, simply pull it out – but do be gentle. You don’t want to damage anything.
Testing the Start Relay with a Multimeter
Once you have the start relay in your hand, it’s time to test it. Shake the relay lightly. If it rattles, it’s damaged and needs to be replaced. If there’s no rattle, use your multimeter to check it for continuity. Set your multimeter to the X1 setting and touch the probes to the relay’s terminals. If your multimeter shows no reading or a reading of zero, the relay is not functioning correctly.
Understanding the Test Results
If your multimeter indicated a problem with your start relay, it’s likely the reason your compressor isn’t working correctly. On the other hand, if the relay passed both the shake and continuity test, the problem could be the compressor itself or another part of your refrigerator. If that’s the case, you might want to consider calling in a professional to take a look.

What to Do if Your Refrigerator Compressor is Faulty
So, you’ve discovered a fault in your compressor? It’s a bit like finding out your trusty steed has a lame foot, but don’t worry, there are solutions.
Replacing Versus Repairing a Faulty Compressor
When your compressor is acting up, it’s time to make a choice: replace or repair. It’s like deciding whether to fix your old car or buy a new one – a tough call, but we’ll help you weigh the pros and cons.
Cost Considerations
When it comes to either replacing or repairing a faulty compressor, it’s vital to consider the costs associated with each option. It’s a bit like deciding whether to keep patching up your old boots or buying a new pair – cost plays a significant role in the decision.
Repairing a compressor can seem like the cheaper option at first glance, but remember that labor costs can add up. You’ll need to pay for a professional’s time and expertise to diagnose the issue, source the replacement parts, and complete the repair. Depending on the complexity of the problem, these costs can escalate quickly. Additionally, keep in mind that once one part of a compressor fails, other parts may soon follow. So, you might find yourself paying for more repairs in the near future.
On the other hand, replacing the compressor involves a larger upfront cost. New compressors aren’t cheap, and you’ll still need to factor in the labor costs for installation. But a new compressor often comes with a warranty, providing some peace of mind that if anything goes wrong, you won’t have to foot the bill for repairs. In the long run, replacing a severely faulty compressor can actually be a more cost-effective solution.
Ultimately, the decision should be based on careful consideration of the current condition of your compressor, the costs of repair vs. replacement, and the potential future costs associated with each option. This decision isn’t just about numbers, but also about value, time, and convenience.
