Smoke Unit Replacement Rail King

They are repairable.  Figure out what failed.  It was a PS-1 unit.  G

I have that in PS3. The S2 turbine. If you don't hear anything under the stack then the fan is dead. If you hear the fan then the resistors that heat the oil in the wick are dead.

It is definitely the fan.

No noise it is the fan.

Fan motor can be bad, impeller slipping on shaft, or a 5V regulator.  I can't remember if that unit had a unique funnel or not.  Or if the more standard type.  G

If the resistors get hot and the fan doesn't run, typically it's the regulator or fan motor, simple fixes.

The unit runs on track power, so it's easy to remove it and work on it on the bench.

Rix Trak,

Here is the link to the PS-1 electronics for steam locomotives; PS-1 Electronics Part List There are several options for a complete PS-1 smoke unit, as well as the parts we have on hand to rebuild your smoke unit. If you are not too savvy with diagnosing and/or fixing electronics I am sure one of the gents on this forum would be willing to resolve the issue for you.

Thank you,
