How to Detect Common Issues With Your Air Conditioner’s Compressor

Your aircon compressor is the heart of the entire appliance.

This means that it’s extremely important when it comes to its operations. The compressor is responsible for several key functions that result in the clean and cool air that you receive whenever you switch it on. 

Unfortunately, given its importance, it also tends to break down easily or experience troubles. If the compressor is not working at its optimal condition, it may lead to performance failure or faults. 

In this article, we take a look at how your compressor functions, and the different problems that you can determine. 

How Your Aircon Compressor Functions

  1. Gets Rid of Humidity 

It’s often hot and humid in Singapore, and many of us know how it feels to be in a humid room. You get that icky and moist feeling and you start sweating. Your clothes begin to cling to your body and it feels stuffy and uncomfortable. 

When your  Toshiba R32 Inverter air conditioner’s compressor is functioning regularly, you feel more comfortable as it removes the humidity from your surroundings. 

However, when it’s not, you can soon expect to feel a noticeable change, with your environment beginning to feel damp and suffocating.

  1. Removes and Helps to Condense Hot Gas

As part of the cooling process, your aircon will produce hot refrigerated gas. The compressor is essential in removing and condensing this gas so that it becomes hotter with a higher pressure. 

  1. Transfers Air 

One key function of your  Toshiba R32 Inverter air conditioner’s compressor is sending heat to the aircon. Once the air goes above the default room temperature, your air conditioner’s vent starts to take in humid air into the unit.

When this happens, the aircon compressor pushes the humid air to the condenser coil. When the air has been completely absorbed by the unit, the compressor begins to drive it into the coil. 

During this important part of the cooling cycle, cold air is produced when the refrigerant converts the air into a cool and comforting breeze that gradually spreads throughout the space. 

  1. Compressed Liquid 

After the air is absorbed into your  Toshiba R32 Inverter air conditioner, the compressor begins to change it into liquid form. After which, it proceeds to an expansion valve that cools the hot liquid.

Next, fluid from the aircon moves into the compressor as a low-pressure gas. When you have a defective compressor, it prevents the liquid from being converted. This leads to warmer air creation even if you have already switched on the cool mode function.

Common Compressor Issues to Spot 

  1. Compressor Motor Not Functioning 

Tried making your compressor motor turn on without any success?

This may be due to a problem with its start capacitor. Check whether your aircon has one installed, and if not, you should consider getting one. 

However, if your unit does have a start capacitor but continues to show operating problems, you should call in an aircon technician to fix this. 

  1. An Aircon That Keeps Switching On and Off

Worried that someone’s playing a frustrating joke on you because your Toshiba R32 Inverter air conditioner keeps turning on and off non-stop? Don’t worry, because the problem is most likely to be an impaired aircon compressor. 

If you choose to leave it be without fixing the problem, it can result in more expensive energy bills because of a rise in energy consumption by your aircon.

However, you should also take note that this issue isn’t always caused by a defective compressor. There are a number of reasons that may lead to this problem. For example, it could be due to a faulty fuse or wire. If you notice your aircon malfunctioning by switching itself on and off even without any tampering, take a look at the fuse and wiring first. 

If you realise that you’ve taken the possible steps without seeing any success, and the issue still continues, you may want to engage a professional aircon technician to help you with the problem. 

  1. Overheating 

Does your aircon feel abnormally hot to the touch? 

It’s normal for air conditioners to overheat in Singapore given our hot climate. One way to identify an overheating aircon is by spotting signs of excessive heat after switching it on for a short period of time.

Some common reasons for this phenomenon are:

  • Blockage of the internal components

  • Defective components that require replacement

  • Infrequent maintenance

  • Faulty wiring 

  • Problems in your aircon compressor 

If this issue occurs, it’s best to leave it to the experts to manage it for you instead of attempting to do it yourself. This is because the professionals better understand how to discern the exact underlying problem and fix


Remember that your aircon compressor is a highly delicate component, which means that you need to take extra care in dealing with it.

This means that if the compressor experiences any problem, it’s best to get your trusted air conditioner technician to determine and fix it for you. Sometimes, the compressor may be broken beyond repair.

When this happens, you have to replace the entire compressor so that your unit can continue working.
