My first Legacy Lionel was a ac6000. I too had the blinking light. I live 50 minutes from Canfield Ohio(Lionels service center). I drove it to them and all the tech did was oil the fan motor. When He was done, I said to him "really, that's it? I could have done that myself and saved 2 hours of my time and a lot of gas money" He replied I couldn't do it myself as it would void the warranty. I even asked...are you sure you don't need to replace that motor? I was reading on the forum that Lionel got a bad batch of fan motors. He replied I should be fine now.
Guess what....3 days later....cab light blinking again. Another roundtrip of 2 hours and a lot more in fuel costs. This time he did replace the fan and admitted to me that He probably should have the first time.
Now let me say this. I think it is awesome that I can drive to the service center and get a repair done on the spot. The tech who took care of me was awesome. Very cordial and professional. I was so impressed I started buying more Legacy locos. I really like the instant service.
Now heres an issue I now have...........In a few months I cannot do that anymore because Lionel is moving the service center to North Carolina. If I had to ship that loco with the bad fan motor back by UPS it would have cost a fortune and a long wait for a 5.00 motor. I would have been very upset. I bought 2 more Legacy NS Heritage locos before I heard the news of the move to North Carolina.I was very seriously considering the New Big Boy coming out but cant deal with the issues that will more than likely arise. I don't want to deal with the shipping back and forth and the waiting times and the worry of getting it back in one piece.
Very disappointed in Lionel moving away to North Carolina......just my 2 cents
