Induction heater repair. Component identification help

I bought an induction heater that doesn't work.

The two IGBT's test bad.

What are the two components circled in red?

I am very interested in learning.

With a volt meter connected to the bridge rectifier negative output and the other lead connected to the IGBT gate terminal, should I see voltage when the button is pressed? Should there be voltage all the time?

Before replacing the IGBT's and the 2 damaged components, should I check any other components?

Thanks for the help!
