Hi,

Have you checked the Battery?

Use Another Battery to make sure everything is all set. There is a screw down deep inside the chimney. Unscrew it and it slides off. You could change the Battery.

If under warranty, should call :-

800-432-5437

That's the Number for their Service Line.

If not Under warranty, let me know and i would let you know, what needs to be done.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Check the voltage on the track from rail to rail. It should read DC voltage and it should increase when you turn the dial. You might have to lightly clean the rails with a very fine steel wool & see if that helps.
