If the drawer isn't opening/moving, it could be because of a faulty (cooked) motor driver IC (or a component in the PS). Maybe you didn't detect the smell at the time, being in a well ventilated space. Now the unit's packed in a box for several days during shipment, and the smell might be detectable once opened.
I don't see how it matters, though. If I purchase a non-functioning item, it is guaranteed to have some failed components, mechanical, electronic, or electrical. What is unclear about that?
