Roger, without the benefit of being able to see more of the PCB & application, is it a soft start circuit ?

The resistor passes a limited starting current but the triac? (if that is what it is) then handles the running current & in doing so diverts the current from the resistor ?

Maybe the triac / triggering device is misbehaving causing too much current through the resistor ?

Good luck, there's nothing like flying blind - done a lot of that lol
