This has the effect that one side will become hot and the other side cold. if the module has been installed the wrong way around it would cause the problem you have. This can be fixed by either dismantling the fridge and turning the module back to front or, easier just reverse the leads to the fridge. These fridges are designed so that you can heat or cool the contents, There could be a switch which is marked cool or heat. It may just be set in the wrong position, which would make the problem even easier to fix.
