Fan Speed Controller Repair | Step-by-Step Guide with Circuit Diagram

In this video, we repair a fan regulator and explain its complete circuit diagram with all components — resistor, potentiometer, DIAC (DB3), and TRIAC (BT136). You’ll learn how the fan speed control system works using a phase control technique and how to test and replace the BT136 TRIAC when it fails. We’ll also show you the working demonstration after repair, including step-by-step testing and replacement of faulty parts. Perfect video for electronics beginners, students, and repair technicians who want to learn how to fix fan regulators at home easily. 📘 Topics Covered: Fan regulator circuit diagram explanation Working principle of DIAC and TRIAC Testing TRIAC (BT136) with multimeter How to replace BT136 TRIAC Potentiometer and resistor role in fan speed control Complete working demo after repair ⚙️ Components Used: Resistor Potentiometer DIAC (DB3) TRIAC (BT136) Wires, soldering tools, and fan load
