I'm trying to remember the brand John, but I've repaired many
of these "switchers" a year or so ago. The company is out of
business, therefore the repair (for an RV company).
There are two low value resistors (10 ohm?) that feed the
gates of the MOSFETs, which open. Simply change these with
higher wattage units and they live happily. Originally 1/4
watt and I swapped them with 1/2 watt.
Pain to take apart but worth it.
