8 Reasons Your Air Conditioner Is Not Working
Considering how hot the weather can be in Singapore, it’s no secret that many households depend on the efficiency of an air conditioner. However, even the best air conditioner in Singapore can still go through constant wear and tear and may have some issues with constant use.
From lack of maintenance to air conditioner breakdowns, we’ll tackle the reasons why your air conditioner stops working and share some tips to fix them.
Your Air Conditioner is Turned Off
This might be an overlooked step, but it’s worth double-checking if you or other members of the household turned your AC off.
Your Thermostat Battery Needs to Be Replaced
The thermostat is an important part of your air conditioner unit. If you notice that your thermostat screen does not display anything, you might want to check if the battery is still working. The next thing is to check the thermostat settings. Make sure that it is set to "cool".
You Need to Reset Your AC Unit
Another simple fix is to reset your air conditioner. Some AC units have a reset function. If your unit does not have it, you can press off manually, wait for five minutes, and turn it on. If this does not work, your unit might have other underlying issues.
The is a Refrigerant Shortage
The refrigerant is a vital part of an air conditioner. A shortage of refrigerant levels can be the reason your air conditioner is not turning on. This can be caused by possible leakage. Refrigerant repairs can only be done by professionals, as refrigerants are dangerous and may cause refrigerant poisoning.
The AC Capacitor is Faulty
If you have some trouble starting your air conditioner, it might mean that your air conditioner capacitor has died down. This can be caused by overheating due to too much exposure to the sun or doubling efforts to reach the desired temperature. A sudden power outage can also affect the capacitor. When the room temperature gets extremely hot, avoid setting the unit at the lowest temperature as much as possible to prevent the capacitor from working harder than it can.
The Condenser Needs Cleaning
Your condenser is one of the most important parts of your air conditioner. If the condenser isn’t regularly cleaned and maintained, dirt and debris can build up and cause the unit to draw extreme current, which can result in a circuit breaker tripping. If your unit isn’t functioning due to a dirty compressor, DIY cleaning may not be advisable as it can damage the compressor. This calls for professional cleaning.
If your air conditioner keeps tripping the circuit breaker, get the help of a professional as soon as possible since it may indicate more serious issues.
Your AC Motor is Damaged
Did you notice some grinding noise from your air conditioner unit before having issues with it not turning on? If so, there is a chance that the motor blades are the problem. This may be caused by the wear and tear the motor undergoes as it ages or a lack of lubrication. Motor issues can be costly to tackle. If your motor is damaged due to the unit’s age, replacing the whole unit might be a better choice than going through frequent repairs.
Your Air Conditioner Needs to Be Replaced
When you google "Why is my air conditioner not turning on?" this might be the last thing you want to see. But if you have been receiving comfortable air quality from your air conditioner for a long time, chances are you have already reached the end of its lifespan.
Here are some indications that your air conditioner has already run its course:
- Your electricity bills have significantly increased.
- Your air conditioner unit is producing weird noises.
- You notice some leaks from your AC unit.

To Repair or to Replace?
Many air conditioner issues can be repaired by professionals. However, if your unit is not turning on due to its age, it's important to consider getting a new one rather than going through the constant hassle of getting it repaired every time it breaks down. The possible cost of repair is a good benchmark to decide whether you want to push through the repair or buy a new one. If the repair price reaches 50% of the new unit’s price, it can be more economical to buy a new one with better energy efficiency and overall value.
