Hard to say what the issue is, the triac is controlled by the uP on the board, so there may be something else going on. I haven't spent much time trying to get these to work, I've just popped a Lionel PCB on them and used them as a dumb unit.

GRJ,

I bypassed the triac and in turn the thermistor circuitry as well. The heating element and fan unit turn on and off in command mode as normal but it no longer has the thermistor function as a fail safe. Do you have the wiring diagram for this loco by chance?
