Re: Westinghouse VR-4625 wont turn on
That is the MOSFET for the PFC Voltage booster, the IC driving is probably bad/damaged, plus may have also burn open the two Source pin of MOSFET resistors connected in parallel to the primary ground.
See if you do have about 360~400VDC on the two legs of the main filter cap (450VDC), the 24V power supply will not work if the boosted voltage is not present.
