It is more than likely the cord may have been damaged. This is a common issue when moving fridges in general. All the time I see where the cord was run over and it is broken inside or cut. Carefully inspect the cord. Look for anything out of the ordinary. Cuts, dents, bare wires.
Let me know how you make out. If you have anymore questions please feel free to ask. Thanks for using JustAnswer.com!
You can replace the cord yourself. Honestly pretty much anything with the same gauge cord can be used. In a case like this, if the replacement cord for this machine isn't available, repair the cord. Get some butt connectors from the hardware store, cut the cord and splice the wires. Cover the repair with some electrical tape and you will be good to go. That is the easiest and cheapest way to fix the cord.
This way is safe also and won't hurt the machine in anyway.
