lionelbob posted:Just got a factory sealed 84328 Polar Express and the chuff stops and starts. I 've read about a cherry switch being the cause. I bought it at Allentown from Just Trains. Do I send it back to them? Send it to Lionel? Pop the screws / void warranty and see if I can adjust the cherry switch?
They are an IR detector on the LionChief Polars - not a cherry switch. If it is not a connector issue with the tender I would call Just Trains and ask them how to handle the problem. It is mounted just behind the front drive axle facing the smoke puffer cam.
I sent one back to Lionel - the first LionChief version - it is an alignment issue.
