Aircon fan not spinning problems are quite common with many aircon units and can turn a comfortable living space into an unbearable one due to lack of cooling. Fans that don’t spin lead to greater energy consumption, poor airflow, and inadequate cooling.
Thus, addressing the issue and knowing the root cause is vital to maintaining a functioning aircon unit. Today, we will discuss seven common problems that can lead to the AC fan not spinning. LS Aircon Servicing Singapore explains the best tips for why aircon fan not spinning. Moreover, they offer professional aircon relocation, aircon installation, and chemical washing services.
Why My Aircon Fan Is Not Spinning
Some of the most common reasons behind the aircon fan not spinning include:
1. Malfunctioning Motor
The fan motor can malfunction due to several reasons. The motor can also wear and tear after long use, leading to the fan getting stuck during its motion. Thus, you will have to inspect the motor once the fan stops spinning, as a faulty motor might be the reason. We also recommend regularly inspecting the fan motor to detect any signs of wear and tear and other malfunctions.
2. Clogged Air Filters
The air filters in the aircon can get clogged after a while. This leads to the airflow restriction through the filters. The fan has to overwork to make the air pass through the filters. This puts extra pressure on the fans, who can eventually stop working.
Thus, we recommend regularly cleaning the air filters to see if they work properly. You should consider replacing the filters occasionally, as their filtration capacity may run out.
3. Issues With The Fan Belt
Some aircon units rely on belt-driven systems to turn the fans and move cool air through the room. If there are any issues with the belt, such as wearing and tearing, the fan can stop working. The belt can also have other issues like misalignment or loosening.
You should inspect the belt regularly for any signs of wear and tear. Consider replacing the belt if the fan stops spinning after a short while.
4. Obstructed Fan Blades
Any foreign object, like dirt or debris, can get lodged in the fan, preventing it from spinning. Some objects like metal pieces can even bend the fans, making a replacement essential. Inspect the fans to see any foreign objects. If you find any, remove them and assess the fans for damage.
5. Tripped Circuits
Tripped circuits are one of the most common reasons for aircon fan not spinning. The aircon can sometimes draw more power than the circuit can handle. There might be a problem with the wiring inside or outside the aircon.
Some other heavy appliances used in the house may also lead to tripping issues as the load becomes more than the circuit can take. Inspect the circuit box to see any tripped circuits and reset them if necessary. If the tripping happens frequently, you should try to find other causes for the heavy load, like wiring issues or appliance overload.
6. Faulty Capacitor
Burnt capacitors can be caused by an aircon fan not spinning. Aircon capacitors can suffer damage after a long time of use. This issue can lead to the fans not spinning. Burnt capacitors can’t run the aircon at optimum temperatures and can lead to the unit not blowing cold air. Capacitor issues can only be solved by replacing the capacitor. Thus, you should consult a technician to replace the capacitor for you.
7. Thermostat Malfunction
If the thermostat is malfunctioning, it can’t signal the aircon fans to start spinning properly. Make sure that the thermostat is working properly. Reset its settings to see and restart it in case of malfunction. If everything fails, you should replace the thermostat to get the aircon fans to spin again.
Conclusion
We have discussed some of the main reasons behind the aircon fan not spinning. Aircon fans only work when the unit itself is working fine. Clogged fans and filters, faulty thermostats and capacitors, tripped circuits, and fan belt issues can lead to users complaining, “My air conditioner fan is not spinning.”
Some of these problems are minor; you can easily fix them with a few tools. Many serious problems can also arise with aircon that need a professional inspection. To fix complex problems with the aircon fans, you can take the help of certified technicians.
