I have the new version of the 175. For the second time, the fan in the smoke unit seems to have failed. Lionel is out of this part. Lionel makes you buy the whole unit to replace the fan. Part is 6104102200. Lists for $15.00.
I might be able to replace just the motor, but not much of a cost savings. Motor part has FF N20PN stamped on the side.
This site - http://www.blunet.net.cn/images/FF-N20PA-PN.htm - suggests there is a FF N20PA version too, but specs are different.
I can find just the motor on bay, but not sure if it's worth it, since the full replacement part is just $15.00.
Since Lionel is out of the part, can anyone suggest another source to buy the whole unit?
Thanks.
