Replace a capacitor on an aircon to improve its functionality and cooling. Aircon units are essential for comfort in hot climates. A faulty capacitor is one of the most common issues that can affect an air’s performance. The capacitor is the component that helps start the compressor and fan motor. This also ensures the unit operates smoothly. When a capacitor fails, your aircon may not start, or it might not cool effectively. The article provides the ultimate guide to replacing a capacitor on an aircon unit.
Replace a Capacitor on an Aircon Unit
Capacitors store and release electrical energy to power the motors in your aircon unit. An aircon unit has two main types of capacitors: the start capacitor and the run capacitor. The start capacitor provides the initial magnetic field to start the compressor and fan motor. The run capacitor offers continuous power to run the system efficiently.
When a capacitor fails, it can cause your aircon to malfunction. Therefore, you need to replace an aircon capacitor to restore the aircon functionality. However, the replacement of an aircon capacitor requires the right skills and tools. LS Aircon Servicing Singapore explains the process to replace a capacitor on an AC unit. They also offer aircon gas top-up, general services, and repair services.
Tools and Materials You Will Need
Before you start the process, keep the tools with you.
- A new capacitor (make sure it matches the specifications of the old one)
- Screwdriver set
- Needle-nose pliers
- Insulated gloves
- Multimeter (for testing the capacitor)
- Electrical tape
Safety Precautions
Working with electrical components can be dangerous if proper precautions are not taken. Always follow these safety guidelines:
Working on electrical appliances is dangerous if you do not follow precautions. You should turn the power off before starting the repair work.
Identify the circuit breaker that controls the current of the aircon and turn it off. If the power is off, the capacitor can still hold some charge. Therefore, an insulated screwdriver is used to discharge the capacitor and bridge the terminals. Be careful and wear the following proper security dress code.
Step-by-Step Guide to Replacing an Air Conditioner Capacitor
Step 1: Access the Aircon Unit
First, you need to locate your aircon unit’s access panel. This is usually on the side or top of the outdoor unit. Use a screwdriver to remove the screws holding the panel. Once the panel is off, you will see various components, including the capacitor.
Step 2: Identify the Capacitor
The capacitor is a cylindrical or oval-shaped component with electrical terminals on the top. It is usually located near the compressor and fan motor. There may be one or two capacitors in the unit, depending on the model. Note the capacitor specifications, which are usually printed on the side. This information will help you purchase a new capacitor with the same rating.
Step 3: Discharge the Capacitor
Before you replace a AC capacitor, ensure it is fully discharged to avoid electric shock. Using an insulated screwdriver, touch both terminals simultaneously to release any stored energy. This step is crucial for your safety.
Step 4: Disconnect the Wires
Disconnect the wires from the capacitor terminals. Make a note of where each wire is connected, or take a photo for reference. This will help you connect the new capacitor correctly.
Step 5: Remove the Old Capacitor
Once the wires are disconnected, remove the old capacitor from its bracket. Some capacitors are connected with a single screw or a clamp. Use a screwdriver to loosen the screw and carefully remove the capacitor.
Step 6: Install the New Capacitor
Position the new capacitor in the mounting bracket with the help of screws. Ensure it is firmly in place. Reconnect the wires to the corresponding terminals on the new capacitor. Refer to your notes or the photo you took earlier to ensure perfect connections.
Step 7: Test the New Capacitor
Test the new capacitor to ensure it is working correctly. Turn the power back on at the circuit breaker and switch on the aircon unit. Listen for any unusual noises and check if the unit is operating smoothly. If everything seems normal, the new capacitor is functioning correctly.
Step 8: Replace the Access Panel
Turn off the power again before you replace the access panel. Hold the panel with the screws you removed earlier. Once the panel is positioned, turn the power back on at the circuit breaker and switch on the aircon unit to ensure it is working properly.
Conclusion
In conclusion, you should replace an aircon capacitor if the fan motor or compressor does not work properly. The above steps help you replace a capacitor in the aircon unit. Keep yourself safe and bring the new capacitor of the same ratings. If you feel any issues, hire professional service providers. Moreover, regular maintenance of the aircon is essential for its correct and seamless functionality.
