How to Fix a Fridge Compressor

A fridge compressor is a crucial part of a refrigerator and needs to be maintained carefully. Over time, it can become noisy, overheated or even falter. In this article, we will discuss some common problems and how you can fix them.

Overload relay

If your refrigerator doesn’t turn on properly or isn’t cooling at all, you may need to fix an overload relay on the compressor. Using a multimeter and a wire tester, you can test the components of the unit and identify the issue.

An overload relay is a device that is part of the circuit used to protect the motor windings from electrical damage. It works by sending current to the run windings when the motor is starting, but stops sending current when the motor is running.

An overload relay is typically a component located on the side of the compressor. Its functions are to provide protection from overheating, arcing and electrical surges.

There are two types of overload relays. The modern ones are generally combined units, while the older models have a separate capacitor and relay. Both are tested using a multimeter.

First, you need to remove the cover from the compartment where the refrigerator is stored. You will also need to remove the power supply.

Next, you’ll need to take the refrigerator off the wall. This requires assistance. Once off the wall, you’ll need to remove the bottom access panel. To do this, you’ll need to untuck the metal connector and then pull the access panel out of its groove.

While you’re removing the cover, you’ll also need to take the time to unplug the unit. Getting this done right the first time can save you money down the road.

One of the most important components in a refrigerator is the overload relay. If you have a defective component, you’ll need to replace it.

For a better understanding of the functions of the appliance’s components, you can also refer to the user manual. It will also have a wiring diagram.


When a refrigerator compressor starts to overheat, it may result in operational failure and increased utility bills. In addition, it can cause bacterial growth. This may affect the quality of your food. If you are unsure how to handle this issue, contact a professional.

Most refrigerators have built-in alerts to notify owners when the compressor starts to overheat. To fix this problem, you must identify the causes.

Typically, the problem stems from the compressor’s condensing coils. Dirt, debris, and other particles collect on the coils, which makes it difficult for the condenser to dissipate heat. The condenser fan is also a contributing factor. A broken or damaged fan will make it harder for the coils to dissipate heat.

Another reason for overheating is a faulty auto-defrost system. A faulty auto-defrost system can cause the compressor to work more than it should. It is important that you do not attempt to defrost the refrigerator on its own.

Other issues can include inadequate ventilation or low thermostat temperatures. While it is normal to turn down the thermostat to reduce the cooling process, you do not want to do so if it causes the compressor to overheat.

You should also keep an eye on the amount of refrigerant that you add. Leaking refrigerant can disrupt the refrigerant loop and cause the compressor to overheat.

If you suspect your refrigerator is overheating, you should first unplug it. You can then use a screwdriver to remove the back panel. Make sure you leave a space at the back of the fridge to allow for proper airflow.

A broken or damaged condenser fan can also cause your refrigerator to overheat. If your refrigerator has scorch marks on the walls, you can be sure that the compressor is malfunctioning.

Dirty coils

When your refrigerator isn’t cooling down properly or shutting off, you might want to check your coils for dirt. Dirty condenser coils can cause your compressor to work harder than it should, causing your fridge to run longer and more inefficiently.

Dirty coils can also make your electricity bill go up. The average refrigerator should be cleaned every six months. However, if you have pets or have a lot of dust in your house, you should clean the coils more often.

Cleaning your condenser coils can be a simple task. First, you’ll need to unplug the refrigerator. That’s important because it avoids shocks. Once the refrigerator is unplugged, you can begin to clean the coils.

You’ll need a brush and compressed air to clean the coils. A flat vacuum attachment can also help. If you have a long-handled brush, you can use that to clean the hard to reach places.

You may also need to get a new dust containment device. You can buy these at your local home improvement store.

After you have cleaned the coils, you’ll want to restart the refrigerator. Make sure to let it cool down for an hour before you plug it back in. This should make the refrigerator run more efficiently and quietly.

To be effective, you should clean the coils in the opposite direction of the airflow. While you’re doing this, you should also check your compressor and fans for problems.

Cleaning your refrigerator coils is easy. Just remember to use proper techniques and supplies. There are coil cleaners available on the market, so you should be able to find one that works for your particular model.

Clean refrigerator coils can reduce your monthly electricity bills, extend the life of your refrigeration equipment, and prevent major breakdowns. In addition, clean coils can decrease your emergency service calls.

Noisy fridge

If your refrigerator is making a loud racket or buzzing sounds, there are a few things you can do to fix it. You can hire an appliance repair professional or buy a new refrigerator. Both methods are cheaper than repairing your current fridge.

The first thing you can do is check for a loose rubber mount. This can cause a noisy noise when you turn on your fridge. Tighten it with a wrench. Alternatively, you can put a thick rubber mat underneath your refrigerator to absorb vibrations.

Another problem could be debris on the condenser fan. It can block the fan’s smooth rotation. Clean the coils to avoid overheating the compressor.

A noisy refrigerator can make your life a misery. Some of the most common causes are debris, overheating, or a malfunctioning compressor. In most cases, the repair cost is relatively inexpensive. However, if the noise is affecting your quality of life, you might want to consider getting a new refrigerator.

If your fridge is making a rattling sound, it might be a sign of water flow. You can try moving your refrigerator to a room with less noise.

If the noise is coming from the rear of the refrigerator, you might want to try moving it into an alcove. This will help trap the sound waves in a smaller area, making it easier to hear.

If your fridge is making a grinding or rattling noise, you may need to replace the motor. You can find replacement parts online for about $100. But before buying any replacement parts, you should check the manufacturer’s warranty. Buying an off-brand refrigerator part can void the warranty.

You should also check the legs of your refrigerator. These can become loose due to general use. Depending on the manufacturer, you can purchase an anti-vibration pad to keep them in place.

Signs of a faltering compressor

If your fridge isn’t cooling as well as it used to, it may have a faltering compressor. When it fails, it can make your food spoil faster. It can also affect your electricity bill. Your refrigerator needs a professional to fix it, so you should contact a trained repair technician.

You’ll know your refrigerator is struggling to cool when it starts to run more than usual. That can mean longer running times or an abnormally high utility bill. But there are other signs you can watch for too.

When a refrigerator compressor isn’t running as smoothly as it used to, it can make strange noises. These might include a loud buzzing or humming sound. Sometimes, it can also make a grinding noise.

If your fridge isn’t turning on or off the way it used to, you should call a technician. A bad compressor can make your refrigerator run longer and harder, which can result in a higher electricity bill. The good news is that it can be fixed without having to replace your entire appliance.

Some of the biggest signs of a faltering fridge compressor include a noisy fan, a clicking sound, or overheating. Leaving these issues unchecked can lead to a larger problem.

The refrigerator compressor is a crucial component of your system. Not only is it the source of heat, but it is also the heart of your cooling system. And a malfunctioning one can derail your entire cooling system.

A faulty refrigerator compressor can cause a lot of damage to your unit. In addition to overheating, it can also result in spoiled food. So it is important to keep it in good condition.
