Como reparar un ventilador Lasko que no funciona y botó el fusible

In this practical tutorial, I'll show you how to repair a Lasco brand fan that seemingly "does nothing" when plugged in. The customer brought it to me because it wouldn't turn on, and in this video, I'll guide you step-by-step through the process of diagnosing, disassembling, cleaning, and replacing the thermal protector, until it's working like new. If your fan has ever stopped spinning or simply won't turn on, this video will help you understand what might be happening and how to fix it with basic tools and a little patience. 🔧 Step 1: Initial Diagnosis I plug in the fan to verify that it doesn't turn on. I determine that the problem isn't external (cable or plug), but internal to the motor. The main symptom: the fan receives power but doesn't respond. 🔩 Step 2: Disassembly I remove the screws and clips holding the casing together. I carefully separate the parts to avoid damaging the plastic components. I observe an accumulation of dust and lint on the motor, causing the rotor to stick. 🧹 Step 3: Internal Cleaning I use a brush to remove the accumulated dust and lint. I gently sand the bushing to facilitate rotor movement. I apply penetrating oil and automotive grease to improve lubrication. ⚡ Step 4: Locating the Thermal Protector I identify that the thermal protector melted due to overheating caused by dirt. I carefully remove the wires and cable ties to access the component. I remove the damaged thermal protector and prepare the replacement. 🔌 Step 5: Replacing the Thermal Protector I obtain a replacement thermal protector from another old fan. I verify its continuity with a multimeter to ensure it works. I install the new thermal protector with insulators and secure it with zip ties. 🛠️ Step 6: Reassembly I reassemble the rotor and field winding, ensuring the connections are secure. I apply grease to the moving parts to prevent future blockages. I assemble the housing, following the marks I made previously to maintain proper alignment. ✅ Step 7: Final Test I connect the fan and test all three speeds. The fan rotates correctly and responds to the controls. I confirm that the problem has been resolved, and the fan is ready for delivery to the customer. 🎯 Conclusion This tutorial demonstrates that many fan problems are due to dust accumulation and a faulty thermal protector. With proper cleaning and replacement of this component, it's possible to restore the appliance's lifespan without having to buy a new one.
