Paul,

I can only generalize, since there's no model number.

First, check and make sure the condenser coils are clean and free of dust or debris.

Make sure the unit is level in both directions(front to back and side to side,front can be slightly higher, less than 1/2 inch).

Make sure that both doors are properly aligned and closing and sealing(all the way around the door(s)).

Could you have spilt defrost drain water or some other liquid into the unit when you moved it ?

These would be the checks I would make, first.
