This article explains what you should do when you see an aircon fuse blown in your Singapore house. Aircon systems are vital in our homes to maintain the cool and comfortable. However, like any electrical appliance, they are prone to problems, including a blown fuse. The fuse in your aircon is an important safety component that protects the system from electrical overloads. When the fuse blows, it can cause the entire unit to shut down. This can leave you sweating in the heat. This article will discuss the seven signs that your aircon fuse is blown and how to fix it.
What Should You Do Upon Seeing Your Aircon Fuse Blown?
When you notice a blown aircon fuse, it is an indication that excessive current has flown in the circuit. Therefore, the first responsibility is to ensure no short circuit in the wiring. If you replace the fuse wire with a new one and you notice the aircon blowing fuse again and again, it is a confirmation of a wiring problem.
The next step is how to fix aircon blown fuse in Singapore. Therefore, LS Aircon Servicing offers technical knowledge on how to fix an air conditioner blown fuse. Don’t forget their aircon installation, aircon relocation, and aircon general services. Here is what you need to do to see an AC fuse blown.
1. The Aircon Unit Won’t Turn On
One of the most prominent signs that your aircon fuse might be blown is when the unit does not turn on. If you’ve checked the power supply and everything is fine, but the aircon does not start, the fuse could be the culprit. The fuse is responsible to control the current flow in the circuit. When it blows, it disconnects the power supply and makes the unit non-functional.
2. No Cool Air
Another common sign of a blown fuse is when your air conditioner is apparently working, but no cool air is being produced. You might hear the fan running, but the air is warm or room temperature. This issue often indicates an electrical problem where the fuse has blown. This interrupts the system’s ability to cool the air.
3. Frequent Tripping of the Circuit Breaker
If your circuit breaker trips when you turn your air conditioner on, it strongly indicates that the fuse might be blown. The fuse is designed to blow when there is an electrical overload to protect your aircon and home from damage. A blown fuse might cause the circuit to overload more, which results in frequent tripping.
4. Unusual Noises from the Aircon
Aircon usually makes a low humming sound when they’re running smoothly. However, if you hear unusual noises, it could be a sign that the fuse is blown. These noises are often caused by electrical issues within the unit, and a blown fuse might be the root cause.
5. Blank Display
Modern air conditioners have digital displays that show all the information regarding the working of the aircon. If the display on your aircon is entirely blank, it means that the fuse is blown. The display requires power to function, and a blown fuse disconnects the power supply and causes the display to go blank.
6. The Aircon Starts and Stops Randomly
Another sign of an aircon blown fuse is the random on-off cycles. This erratic behaviour could be due to an inconsistent power supply. A fuse can be the primary cause of an inconsistent power supply. A partially blown fuse might still allow some power, but not enough to keep the aircon running steadily.
7. A Burnt Smell Near the Aircon
If you notice a burnt smell near your air conditioner, it could be a sign that the fuse has blown. The burnt smell is often caused by electrical components overheating due to the fuse failing to protect the system from an electrical surge. If you smell something burning, it’s essential to turn off the aircon immediately and check the fuse.
How to Fix a Blown Aircon Fuse
When you become familiar with the signs of a blown fuse, you should know how to fix the issues. The repair work is not too difficult, but it requires some basic electrical system knowledge. Here’s a step-by-step guide to fix an aircon blown fuse:
Step 1: Turn Off the Power
Before you do anything, ensure to turn off the power to your aircon. This is essential for your safety. You can turn off the power at the circuit breaker or unplug the aircon unit if it’s portable.
Step 2: Find the Fuse
Next, you’ll need to find the fuse. The fuse is usually located in the disconnect box near the outdoor unit of your air conditioner. Open the disconnect box to check the fuse. If you’re unsure where the fuse is, consult your air conditioner’s manual.
Step 3: Inspect the Fuse
When you locate the fuse, remove it and inspect it for any signs of damage. A blown fuse will usually have a broken filament and will get blackened. If the fuse looks damaged, it’s likely blown, and you must replace it immediately.
Step 4: Replace the Fuse
If the fuse is blown, you must replace it with a new one. Use a fuse with the same amperage rating as the old one. You can find this information on the fuse itself or in the aircon’s manual. Insert the new fuse into the disconnect box and close the cover.
Step 5: Restore Power
After replacing the fuse, restore power to your aircon by turning the circuit breaker on. Turn on the aircon to check if it’s working properly. If the aircon starts up and cools the room, the issue has been resolved.
Step 6: Test the Aircon
After replacing the fuse and restoring power, test your aircon to ensure it’s working properly. Set the thermostat to a cool setting and let the aircon run. If it operates smoothly and cools the room, the problem is resolved.
Step 7: Call a Professional if Necessary
If you’ve replaced the fuse and your aircon is not working, it’s time to call a professional. There might be a more serious electrical issue that requires professional assistance. A qualified technician can diagnose and fix the problem safely.
Conclusion
An aircon blown fuse is a common issue that can cause it to stop working. You need to identify the problem with the fuse or any other component. If the fuse is blown, it can be easily replaced without professional assistance. However, if you’re unsure or if the issue persists, it’s always best to call a professional to ensure the safety of your aircon unit.
