Hello all,
I am attempting to repair a F6645BA01GP microwave inverter PCB (photos attached). The shorted bridge rectifier tripped the circuit breaker.
Before anyone mentions it, I did check that all the high voltage capacitors were discharged before testing the components on the PCB.
The IGBT doesn't seem to be shorted.
What is likely to have caused the bridge rectifier to short out?
