Inverter troubleshooting step by step

In this video, I show you how I repair an inverter step by step, from diagnosis to final testing.
First, I checked the IGBT transistors and diodes, which, to my surprise, were all in good condition.
Then I built and replaced the damaged blades that provide contact between the transistors and the circuit board.
The PCB was thoroughly cleaned, removing water traces and residues that could affect operation.
I carefully reassembled all components and simulated the thermistor using a potentiometer set to 1.8 kΩ.
Finally, after testing, the inverter works correctly and is ready for startup.
This video is useful for anyone interested in troubleshooting and repairing industrial inverters.
