I have a problem with an induction furnace heat treatment makes it a car part, it does generate heat through high frequency induction that generates an IGBT but time after starting the duty cycle have a high frequency alarm you used to do it occasionally but now followed .. any of you can help me thanks ....
 
What brand induction heater? Have you contacted they yet?

What I see more than anything else is the cooling water failing.
What is the driving frequency are you outside of the excepted range?
