Lionel 38071 Smoke Bowl Temperature

Thermistor Question

This may help with your question.

There is talk of smoke unit temps within.

Dave, judging by that thread,  218F on the case is not out of the ordinary;  guess its good to go; thanks for the link; Falcon

I know they get hot enough that I'm not interested in putting my finger on them, but I haven't actually measured the case temperature.  As long as they're drawing the right amount of current and producing reasonable smoke, I figure they're working.

Now, if the smoke regulator shorts, which happens from time to time, they'll get a WHOLE LOT HOTTER!  I had the privilege of seeing that happen in person once, it was spectacular!  The locomotive came out of the tunnel and the owner said "I never saw it smoke like that".  After about five seconds I realized that a Legacy locomotive doesn't smoke like that and hit the power disconnect.  It runs fine now, I replaced the regulator, smoke PCB, resistor, wick, impeller, smoke motor, etc.  The smoke bowl survived, but the locomotive still smells like burnt fiberglass.

John; been there!  Its spectacular; also changing a traction tire on this puppy is no fun! Take care; Falcon
