Top 3 Customer Questions & Concerns 🙋‍♂️

💨 Why is my fan spinning slower than it used to? A slow-spinning fan is often caused by a weakened capacitor. Over time, these components lose their ability to hold a charge. Replacing the old unit with a new capacitor of the exact same µF rating usually restores the fan to its original speed.

📏 Can I use a higher µF value to make my fan faster? It is strongly recommended to match the original value. Using a significantly higher µF rating can cause the motor to over-torque and overheat, potentially leading to permanent motor failure.

🛡️ What does the "X2" or safety mark on the casing mean? The safety markings indicate that the capacitor is designed to fail safely. If it encounters a massive power surge, it will "open" the circuit rather than catching fire, protecting your home and the appliance.
