Brand new motor not working?

[spzero]

Hi, I recently sold a motor on bricklink and it was returned as not working, now I pulled the motor out of a sealed bag which was in a sealed box, so this was brand new only ever held by me to put in a jiffy bag, I never tested the motor as it was new but a unhappy customer said it dosent work, Ok return it I said.

Now Its here but shows quite a few marks i cant prove its a different motor than I sent but I have my suspicions due to said marks on motor, so how likely is it the motor was a dud from lego,

The motor in question was a

Light Gray Electric, Motor 9V Mini-Motor, older heavier weight

from the znap black mobile set although its a znap set its a normal lego motor

i cant turn the motor axle by hand i think the motor is seized somehow

any help would be appreciated

Ask your customer, "Are you sure you returned the same motor?"

and fraud is part of any sales... just an expense you have to plan for and accept. Some you can avoid (when I sell my used electronics on ebay, I record the serial numbers so a buyer can't swap their dead unit in a return) but some you just have to eat.

Hi

if it is seised, it probably burnt out when the customer tested it.

You know on airfix kits there is extra moulding (flash) that is not wanted?

I suspect that there is some of that on the planetary gears, therefore locking them up.

As this motor is no use to you at the moment, i would advise "exploratory surgery" inside it, it cant make it any worse than it already is!

Some moddeling tools and a screwdriver is all you should need.

Hope this helps
