N Gauge class 33

[Lego Jaeson]

Hi. I have a n gauge class 33 after a minutes running it slows down and sometimes comes to a complete stop without me changing the speed. However sometimes it will run fine. It will sometimes get hot. It happens in both directions. Any ideas what can be done to fix it other than returning it. 

Many thanks regards Jaeson

DC or DCC?

 

How does it run if you remove the body, unplug the lights and run it just as the chassis on its own?

Hi Steven. Thank you for the reply. It runs on DC no decoder is fitted it also runs the same with the body off. The motor gets hot too after a short run. I ran it just now and the speed was set to 50 on the controller and went to a complete crawl in about 3 minutes. 

Many thanks

Sounds like resistance is building up somewhere. Can you open it up and try applying power can you remove the motor and apply power to it. Does it still get warm? If so the motor is the problem.

Hi Kris. Thank you for your reply. Yes I have opened it up and run it like you said and it is still unfortunately the same. I will try and send it back. I have had the same problem with a class 86 and their HST. The 86 had a new chassis and the HST had a new motor.

Sending it back seems like the best option.
