If you want to know why your refrigerator’s compressor gets heated you are in the right place.
The compressor is a major part of your refrigerator, it is responsible for keeping the inside of your refrigerator cool.
Keeping the refrigerator cold, the compressor sometimes gets overheated and it starts to make concerning noises.
Commonly there are five reasons why your compressor is hot. These reasons are: the cooling system does not have refrigerant, the condenser fan has stopped working, the compressor is old, or you have placed your refrigerator in a place where there is way too much sunlight.
Refrigerator Compressor Hot or Refrigerator Compressor Overheating?
In this article, we will discuss all five of these reasons in detail and we will also talk about how you can fix your hot refrigerator compressor or refrigerator compressor overheating
This is one of the reasons that cause your refrigerator to have a hot compressor or refrigerator compressor overheating.
Now you may wonder what is a thermostat. A thermostat is basically the part of the fridge that activates the compressor.
When the thermostat figures that the fridge is way too warm inside, it activates the compressor so that it can maintain the temperature by generating cold air.
Now when the temperature on the inside of the fridge is maintained the thermostat will shut off the compressor until the fridge is warm again.
If your fridge has a faulty thermostat, it will not know when to stop the compressor and hence the compressor will keep working even when it does not have to.
Since the compressor works all the time, it will eventually start heating up. Your fridge will have a mechanical thermostat or an electric one.
Electric thermostats are used more commonly these days.
If you know what type of thermostat your fridge has, you can find out the problem and the solution.
A faulty thermostat is one of the main reasons why your compressor is heated. If you know the exact type of thermostat that is used in your fridge you can easily find a replacement.
Why is your thermostat not working?
There are many reasons why your fridge’s thermostat may not work. The most common reason why the thermostat is not working is that it has become faulty due to old age.
If you have not changed your thermostat in a while and you have been using your fridge for a long time there is a huge chance that your temperature thermostat is faulty because of old age. If you have not maintained your fridge you might also want to look out for other faulty components.
When it comes to electronics like fridges you must keep in mind that the inside will expand and contract repeatedly. Hence the temperature will rise and fall throughout the day.
During the constant rise and fall of the temperature, your thermostat might break slightly causing moisture to seep inside. The moisture can be very harmful to the thermostat itself.
The sealed system does not have enough refrigerant:
The inside cooling of your refrigerator depends on the closed system/ loop that circulates the refrigerant through the entire fridge.
The compressor is used to pressurize the refrigerant so that it keeps circulating through the closed-loop and hence it keeps the fridges cool.
Now the compressor can only perform its job if the correct amount of refrigerant is present in the sealed system.
Why is the refrigerant not enough?
If the fridge even has a small leak it can cause the refrigerant to leak out and hence this will stop the fridge from maintaining and cooling down its temperature.
Since there is a lack of refrigerant in the sealed system. The compressor will have to work extra hard to maintain the temperature of the fridge and hence it will become overheated as time passes.
Small leaks in the closed-loop will cause the refrigerant to leak. Mostly these leaks are caused by heavy impact usually when a part of the fridge hits a wall or when your moving the fridge and it faces some heavy impact. These leaks can also occur as side effects of rust. It can also happen due to the old age of the fridge.
How to fix the sealed system:
Now in order to fix your sealed system, you will have to follow the below-mentioned steps:
The first step of the method is very easy all you have to do is find the spot where the refrigerant is leaking. The leak might be a singular leak or there might be a lot of places where the refrigerant is escaping from in the closed-loop system.
It’s very important to fix these leaks first, you can fix these leaks either by soldering them shut or you can replace the piping entirely. Once you have fixed all of the leaks you can move on to step 2.
If you have performed both of the steps, you can recharge the closed loop with the correct amount of refrigerant.
NOTE: It is best that you call a professional for help. Since refrigerant gas can be very harmful you should not try to work with them
The compressor is faulty:
Like we talked about, the compressor is responsible for maintaining the temperature of your refrigerator by compressing the refrigerant and helping it circulate. Now if your compressing is worn out or it is old, it will start working harder to do its job properly.
If your compressor is not working properly it will consume way more energy than it is supposed to and it will generate extra heat in order to do its job properly.
The extra heat and the excess energy will cause the compressor to overheat and it will start making buzzing sounds.

Why is your compressor not working?
A compressor may become faulty if there is too much or too little refrigerant in a sealed system. If there is too little or too much gas in the closed system, it will put too much pressure on the compressor. Hence the compressor will be strained and it will break down.
Frozen or dirty coils in the fridge can also cause compressor failure. If the coils are dirty or frozen they will cause blockage in the closed-loop and hence put more pressure on the compressor.

How to fix a faulty compressor?
The solution to a faulty compressor entirely depends on the cause of the problem. Depending on the problem you can use one of the below-mentioned methods to fix the compressor:
If there is a problem with the refrigerant, you should call a professional for help. A technician will balance out the refrigerant by adding or removing gas from the closed-loop.
The technician will also help you clean or repair dirty and frozen coils. This will get the system working smoothly again.
refrigerator compressor hot AND refrigerator compressor overheating
The sunny side:
Sometimes, the fridge is placed in a location that experiences too much direct sunlight. Placement of this sort can cause the compressor of the fridge to heat up in hot weather.
If there is too much sunlight then the compressor might become hot because the sunlight heats the compressor directly or because the compressor has to work extra hard to cool the fridge down.
Now as we talked about a compressor is supposed to help the fridge cool down and remove heat. The compressor’s job becomes difficult when there is too much sunlight near the fridge. Hence the compressor has to work extra hard to maintain the temperature.
How to solve this problem?
The solution to do this is very straightforward and you can easily solve this problem. To solve the problem all you have to do is move the fridge to a place that is away from direct sunlight.
You can place your fridge in a place where there is plenty of airflows. This will help the compressor maintain the fridge’s temperature.
