Hola Recuerdo hace 35 años en nuestros proyectos de amplificadores de audio eliminábamos ruidos de fuente usando 0.1 mf ,eso solo para limpiar las frecuencias de audio, me imagino al interior de la cocina de inducción de producirse mucho ruido por radiofrecuencia ,que probablemente altera las polarizaciones y desencadena el deterioro del IGBT

I have used FGA25S-125P. The picture of old IGBT, which failed is there in the article at the last. Many thanks for your comments!

Good detecting repair!!One of fix caps measure 108n, is it abnormal too? Again I observed number of fix caps after repair is less than before repair on the board.why?
