What if your aircon stops working on a blazing summer day in Singapore? This article will cover all the reasons for such an event and what you should do in response. Air conditioners are a necessity in Singapore rather than a luxury.
However, there are times when your aircon may suddenly stop working just when you need it the most as exemplified above. This can frustrate you and cause discomfort in your home. In this article, we will explore seven common reasons why your aircon might stop working when it’s hot outside and what you can do to fix these issues.
Why Aircon stops working?
On a hot summer day, if your aircon stops working, you may wonder why my aircon is not working, but you cannot spot a reason if you are unaware of the most probable reasons. You should know the reasons why your aircon stops working when hot outside.
Therefore, LS Aircon Servicing Singapore explains the top seven reasons that can cause an aircon to stop working. Moreover, they also offer aircon repair, aircon relocation, and aircon installation services at the most affordable price in Singapore.
1. Overheating of the Aircon Unit
Overheating is one of the most common reasons an aircon stops working in hot weather. This is because the unit overheats in this condition, which causes the aircon to malfunction or stop working.
The aircon works harder when the temperature rises, so it starts overheating. When this happens, many aircon units have a built-in safety mechanism that automatically shuts down the unit to prevent damage.
Solution
To prevent this issue, clean and maintain your aircon regularly. Moreover, if the unit is exposed to direct sunlight, try to provide shade over it. This is essential to prolong the lifespan of the aircon.
2. Clogged Air Filters
Air filters are crucial to blocking pollutants and spreading fresh air inside the room. However, the filters get dirty over time and become clogged due to excessive dust accumulation. This makes it hard for the unit to push the air inside the room.
Therefore, the aircon works harder, and overheating can cause further damage to the system. This issue is more likely to occur during hot weather when the aircon has to run continuously.
Solution
Cleaning the air filters regularly is necessary, and you should arrange a cleaning session every month. Moreover, to avoid excessive clogging, you should also replace them every three months, especially during the summer.
3. Refrigerant Leak
The refrigerant in your air conditioner cools the air. If there is a leak in the refrigerant line, the system won’t have enough coolant to cool the air effectively. This is crucial on hot days and will ultimately cause the unit to shut down.
Solution
If you feel there is a refrigerant leak, it’s best to contact a professional technician. A refrigerant issue is not something everyone can handle. Therefore, you need the services of an experienced and licensed technician to do this job.
4. Condenser Unit Blocked
The condenser unit releases heat from inside the room. When the weather is scorching, this unit has to work an extra yard, which demands its super health. If pollutants clog the unit, it will struggle to release heat effectively. This can cause the air conditioner to overheat and shut down.
Solution
Keep the area around the condenser unit clean and free of debris. Moreover, it is better to provide shade to it.
5. Faulty Capacitors
A capacitor provides the initial rotary motion in single-phase systems by providing the rotating magnetic field. However, capacitors can wear out like other components and cause the unit to struggle. This results in a unit that struggles to turn on or turns off and on continuously.
Solution
If you notice that the aircon is making a humming sound or struggling to start, it could be due to a faulty capacitor. In this case, contact a professional technician to replace the capacitor.
6. Thermostat Issues
Sometimes, the issue might not be with the aircon unit itself but with the thermostat. If the thermostat starts malfunctioning, it will not detect the rising temperatures and fail to signal the aircon to cool the room. This is the most unwanted scenario on hot days.
Solution
Ensure the thermostat is functioning properly and is not in direct sunlight. If you feel this is the issue with your aircon, contact a professional technician to resolve it as soon as possible.
7. Poor Ventilation
Hot weather forces the unit to work extra hard to maintain the desired temperature in the room. Poor ventilation could limit airflow in your home. As a result, the system has to work harder, and it eventually shuts down overheating. Rooms with poor ventilation make it even harder for the air conditioner to cool the space effectively.
Solution
Ensure that all vents are open and unblocked. Moreover, improve overall ventilation in your home to ease the burden of your aircon.
Conclusion
When your aircon stops working on a hot day, it can feel like a disaster in Singapore. The main reason that forces an aircon to stop working is overheating. However, the unit can overheat for several reasons, as explained in detail in the above sections.
Moreover, a faulty capacitor can also be the reason behind a struggling aircon. Therefore, it is essential to clean and maintain the aircon and use it efficiently to keep it in good condition.
