Dear everyone,
I have a induction cooktop, It was lose power. After checking the circuit, I detected a pulse transformer with 4 pins in layout. My trouble is, the current was sourced by both two coils of transformer, (I think both is secondary coils as diode directions), so where is the primary coil of transformer. Please take a look and help me!
Thanks in advance!

I can't make out the function of that transformer, but what is the blackening of the tracks near the left hand side of that picture?

Pulse transformers are used for signal level processing and don't usually handle large amounts of power. Why do you think it failed?
