How to Find a Shorted MOSFET - safe & fast, just a multimeter, no thermal camera

How to Find a Shorted MOSFET - Troubleshooting Guide In this video, we will guide you on how to identify and locate a shorted MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) in electronic circuits. MOSFETs are commonly used in various electronic devices, and a shorted MOSFET can cause a malfunction or complete failure of the circuit. Whether you are a beginner or an experienced electronics enthusiast, this step-by-step troubleshooting guide will help you diagnose and isolate the faulty MOSFET. By following these instructions, you can save time and effort in identifying the source of the problem. 1 - Symptoms of a Shorted MOSFET: Learn about the common signs indicating a shorted MOSFET, such as excessive heat, circuit malfunction, or abnormal behavior. 2 - Testing Equipment: Gather the required tools, including a multimeter (preferably with a diode/continuity testing mode) and a soldering iron for component removal if needed. 3 - MOSFET Testing: Demonstration of step-by-step MOSFET testing methods using a multimeter. This includes measuring resistance, checking diode mode, and examining gate-source voltage. 4 - Removing the Shorted MOSFET: If the MOSFET is confirmed to be shorted, we show you the proper technique to desolder and remove the faulty component. 5 - Replacement and Reassembly: Guidance on sourcing a compatible replacement MOSFET and soldering it back onto the circuit board. Tips for reassembling the circuit and ensuring proper connections. 6 - Testing the Repaired Circuit: After replacing the shorted MOSFET, verify the circuit's functionality by performing relevant tests and checks. Remember, troubleshooting and repairing electronics can be challenging, so it's essential to approach the process with patience and caution. This video aims to equip you with the knowledge and skills necessary to diagnose and resolve a shorted MOSFET issue effectively.
