MTH 20 -5610 PS2 GG1,PUFFER SMOKE ISSUE

Take shell off and inspect.  Fan does not run all the time it might pulse some.  It also reduces heat until ready to do the boiler releases.  I have not looked up your model, but some have large smoke units and others small.  If you have a small smoke unit, you really need to not add too much fluid.  Picture would help.  G

Since you have smoke when you blow into it, we can guess that the problem is the smoke motor.  Assuming that you are running it with DCS you can try this to confirm that it is the motor:

• locate the softkey FPR press it once.  After about 2-3 second you should hear the pressure release sound and see smoke (or not).
• turn the volume all the way down and press FPR.  You should hear the smoke motor.  If not it is the motor.

Remove the smoke unit from the locomotive and check the motor by applying 3-6 volts DC.  If it works, the problem maybe one of the FET’s that turn it off and on.  If it doesn’t work, replace the motor.

If you are uncomfortable taking it apart, contact one of the MTH techs on the forum.

Thank you, Jerry

Thanks for your reply. I do not have a fpr key but I do have a PFA which is number nine. As mentioned before I was running on my tablet. Please advise again what you do. Do you have any idea where I could get a motor if I need one?

Much thanks again, Jerry I live in Michigan

Jerry , the air coming out of the smoke stack maybe hard to feel but if you shut down the engine sound and cycle through the on /off smoke key , you should be able to hear the fan running and stopping if it is working .

you only want to apply 1.5 volt battery to smoke motor when board HAS BEEN DISCONNECTED, otherwise you can damage the board! if the motor won't run  on 1.5 volts the smoke motor is BAD!  and needs to be replaced ! you know you might have flooded your wick and if saturated with fluid it will possibly never smoke and have to replace the wick! they are very cheap from Mth but from MTH the minimum order is 5 motors if they have them in stock!

Thanks for all your help. I don't know if I want to take it apart blow everything else up for just cough now and then. On the other hand if it's just a wick maybe I can look into that.

Again, much thanks, Jerry
