One of the necessities of a fully functional refrigerator. As if it were a beating heart, most of the electricity flows through and around the structure.
For most humans, the heart controls the circulation of blood, which provides oxygen and nutrients to every cell. As we delve deeper, you’ll see more parallels between the human heart and its compressor. We absolutely need a fridge in our home. It’s a must-have item for our household and one of the most crucial ones. Its throbbing heart, the Compressor, is explained in greater detail below.
How Different Compressors Work
1. The Reciprocating Compressor
A piston that moves back and forth compresses the evaporated refrigerant. Piston compressor is another name for the reciprocating compressor. The motor, crankshaft, and cylinder heads of this compressor come with a few pistons.
The motor turns the crankshaft, which spins the pistons.
Pumping, compressing, and discharging all happen simultaneously while the crankshaft rotates. This is the proper sequence of events. Since the gas flow is disrupted, this causes the object to vibrate.
It is a single-side refrigerant-using type of reciprocating compressor. A double-acting compressor uses refrigerant to cool the piston on both sides.
There are several distinct varieties of single-acting compressors.
- Open-Type Compressors.
- Semi-Hermetic Sealing Compressors that Actually Perform
- Compressors with Semi-Hermetic Bolted Serviceability
- Welded Hermetic Compressors
There are reciprocating compressors for use at low, intermediate, and high temperatures. Reciprocating compressors are used in fridges and freezers (welded hermetic compressors). Commercial refrigeration and air conditioning systems frequently use semi-hermetic and welded hermetic compressors.
2. The Rotary-Vane Compressor
A vane separates the suction and discharge halves of the cylinder. A change in section volume is achieved through a rotation of the pistons. Gas is sucked in, compressed, and released by continually rotating the gas.
There are five phases to a rotary vane compressor. What happens is a sequence of sucking, compressing, and releasing. Each rotation of the crankshaft results in the completion of all five of these tasks.
A/C and refrigerators use the same type of compressors. Also, they are a standard part of heat pumps.
3. The Rotary-Screw Compressor
Helical screw rotors allow for more efficient compression of more refrigerant. Compression is a team effort including the motor and both the male and female rotors.
The male rotor is rotated by the motor, which is driven by the crankshaft. Each time the male rotor spins, it advances into the path of the female rotor.
When the rotors of a compressor mesh, it forces the suction port to open. High-pressure refrigerant is released from the compressor.
However, screw compressors face competition from both small centrifugal compressors and large reciprocating compressors. Rotary screw compressors are commonly used in HVAC and refrigeration systems in commercial and industrial settings.
4. The Centrifugal Compressor
The centrifugal compressor is sometimes called a turbo compressor or a radial compressor. The kinetic energy of the spinning impellers compresses the refrigerant. Rotating impellers force the refrigerant through the inlet vane. When the impeller’s rotational speed is increased, so is the resulting pressure.
The high-pressure refrigerant is cooled as it passes through a diffuser. As the gas’s speed slows in the diffuser, the volume of the refrigerant gas increases. Centrifugal compressors transform the energy of high-velocity, low-pressure refrigerant. As a result, a low-velocity, high-pressure gas is produced.
When it comes to massive cooling systems, centrifugal compressors shine. The centrifugal compressor is widely used in commercial and industrial refrigeration.
Compressors can serve several functions because of the variety of mechanisms by which they work. Engineered compressors may not be suitable for other applications. Crucial considerations are cooling capacity, cost, efficiency, and reliability.
Things You Need To Know About A Fridge Compressor
What is a refrigerator compressor, to put it another way? You might inquire aloud, “What the heck is a fridge compressor?” if you’re in the market for a new fridge and someone asks you, “How does the compressor work?” The refrigerator’s compressor is a fantastic spot to start looking if you want to know how well it works beyond first impressions. Because the refrigerator’s compressor provides the driving force, understanding its inner workings is essential.
Increases pressure in the refrigeration system’s hotter sections and improves circulation of the refrigerant.
This causes the refrigerant to rapidly heat up. A frequent metaphor is filling a bicycle tire with air. A pump’s temperature will increase as air is compressed. To move the refrigerant across the system, it serves as both a pump and a motor. Yet another liquid, this one increases the pressure of your refrigerant.
Can a fridge work without a compressor?
If you want to know if a refrigerator will cool properly without a compressor, read on. A human being cannot continue to function without a functioning heart. A single fact was impossible to overlook.
A refrigerator is analogous in this respect. In order for this to function, compressors are essential. Vapor is compressed as pressure builds in this part of the refrigerator. Since this is the norm, obviously everything turns out fine. If the refrigerator’s compressor breaks, it won’t be able to maintain a safe temperature inside. This is the place to look if you’re curious about the compressor’s capacity. It’s important that you know how to check your fridge’s compressor.
Where to buy a compressor?
This is another popular inquiry. If the compressor in your refrigerator suddenly stops operating, now is the time to take action. If you can’t afford a whole new fridge, you can always only get the compressor fixed. Taking it to an appliance repair business will yield a wealth of information. Perhaps that is where you’ll find the compressors. They are able to supply both the product and the service.
It will require a skilled team to repair, so plan accordingly. However, if you or someone you know is capable of repairing or replacing the compressor, you can save money by purchasing just the compressor. I’ll give you two options from which to choose.
Option #1. Online purchase
If you need a compressor, one of the most hassle-free ways to get one is to order one online. That way, you won’t have to risk going out into the world. In addition, you have a wide range of options to choose from. This is the most practical choice for people who live far away from a shopping center or a store carrying the product in question. If you do some research online, you can find many stores that carry this model, along with many others.
Variations in compressor sizes are available. One deciding element is often the size of your refrigerator. While it is important to purchase your compressor from a trustworthy vendor, preference should be given to those that have received particularly excellent ratings.
The one potential downside is that you could have to pay for shipping if the store is far from where you live.
Option #2. Check out the appliance center
Your local appliance store is your second best bet for finding a replacement compressor that will make your refrigerator more energy efficient. Most people buy their appliance parts here. Since a refrigerator’s compressor is an integral part, it stands to reason that they would try to sell one. Keep in mind the brand and size of your refrigerator before making your purchase. Make sure you have a plan before you go shopping, or bring a friend along to help. You should prepare for the expense of a refrigerator compressor by finding out what it typically costs.
How Much Does It Cost to Repair a Refrigerator Compressor?
Electronic pumps called compressors are located on the rear of the refrigerator and are responsible for pumping refrigerant through the system. This region of the brain is responsible for the perception of humming sounds. The typical cost to fix a faulty refrigerator compressor is between $50 and $300.
When the refrigerator’s internal temperature increases above the preset limit, a warning signal is sent to the user. The compressor starts pulling in the cold refrigerant gas to refill the hot air inside the device. If things aren’t going as planned, there’s no point in saving space in your fridge for dinner leftovers.
If your refrigerator’s compressor fails, you can order a replacement online or speak with a service technician.
How Much Does It Cost to Replace a Refrigerator Compressor Yourself?
A qualified technician is required for this repair due to the potential for refrigerant gas leakage from the refrigerator compressor. There should be no leakage of the refrigerator’s gases. Also, a trained technician would know how to fix a compressor without compromising the integrity of any frozen parts. The going rate for an hour of labor to fix a refrigerator’s compressor is between $100 and $200. This may take a few hours to complete.
Troubleshoot the Refrigerator Compressor Problem
By checking for the following issues before calling a repairman, you can save money on a service call or even prevent having to call one altogether:
- Be sure the refrigerator is turned on and the temperature is correct before using it (at or below 40 degrees Fahrenheit while the freezer should be at 0 degrees Fahrenheit).
- To inspect the area behind it, you can disengage it from the wall and the frame. No obstructions in the fan’s rotor or the coils. Don’t forget to unplug the refrigerator and give it a good vacuuming while you’re back there. Doing this every year will be beneficial.
Pull it out from the wall and out of the frame to have a look behind it. There are no impediments in the rotor or the coils of the fan. While you’re in there, unplug the refrigerator and give it a thorough vacuuming. This is something that should be done annually.
Refrigerator Compressor Cost Breakdown
The money you save on groceries could pile up over time. However, as a precaution, you may wish to keep them in a cooler or your neighbor’s refrigerator. The following is an estimate for the price of a refrigerator compressor:
- A used compressor can be purchased for as little as $35.
- A fresh new compressor could cost as much as $450.
- The average hourly rate for fixing a refrigerator’s compressor is between $100 and $200.
It usually costs between $200 and $300 to fix a refrigerator, but can cost anything from $40 to $1,000.

Depending on the nature of the issue and the materials required, the cost to repair a refrigerator or freezer can range from $200 to $400.
Fridge Relay Switch Cost
A faulty relay switch could be at blame if your fridge is running but not cooling. The price to replace a relay switch might range from $50 to $200.
Refrigerator Leak Repair
If you smell something chemical, it could be a leak in your refrigerant system. As a general rule, you should never have to replace the refrigerant in your system, although this situation does arise. If you smell something unusual coming from your fridge, call a repair agency right away. An estimated $200-$300 is needed to fix a refrigerant leak.
How do I know if the refrigerator compressor is broken?
Your refrigerator’s compressor has probably broken if its no longer freezing your food. Before calling for help, make sure the fridge has power and is at the right temperature (at or below 40 degrees F while the freezer should be at 0 degrees F).
In order to check what’s behind it, you should move it away from the wall. Is there anything blocking the fan or the coils? Seek the help of a qualified appliance repair technician if this is the case.
When should I replace a refrigerator?
If your refrigerator is older than 15 years, it is time to get a new one. A new refrigerator can set you back between $1,000 and $1,500. A few hundred dollars spent on a repair could add years to the life of a newer refrigerator.
It’s estimated that the average refrigerator will last between 10 and 15 years, however certain models have been known to last for 27 years or more.
What are some signs the refrigerator needs service?
A repair or replacement of your refrigerator may be in need if it is making strange noises or is failing to keep food cold. In most cases, the price to fix a broken fridge or freezer is somewhere between $200 and $330. Among the most often encountered problems are:
- Problems with the fan could cause the compressor to become uncomfortable to the touch or to make an odd noise.
- Symptoms of a faulty start relay include a clicking sound and warm air escaping the fridge.
- It’s possible that the evaporator is broken and generating an odd noise. Examine the source of the temperature difference between the fridge and the freezer.
How can I repair a refrigerator compressor on a budget?
If your refrigerator’s compressor ever fails, you have a few options.
For less than $35, you may find a new or used compressor, which is the least expensive option. After this, there’s a good chance that the refrigerator will need to be replaced again.
The last option is to get a new compressor, which can cost anywhere from $300 to $550 including labor and parts.
The most expensive option is likely to be purchasing a new refrigerator, which can cost up to $1500. This might be your best bet if your refrigerator is older than ten years.
