Reply to "Smoke unit thermistor - what ohm rating?"

Good question, there is no information on what's in those, so I'll be interested to see if someone actually has some information on it.

Lionel has told me that the thermistor should be 50,000 ohms +/- 2,500 ohms.

Since mine is measuring at 62,000 ohms, it's failed, and it's causing the electronics to think that the smoke unit is too hot and to shut it down.

As it happens, the thermistor is not available by itself. I need to buy the smoke unit board. But heck, I wasn't looking forward to soldering on the PCB, anyway. I prefer soldering jobs that require less finesse.
