Indesit UFAN400NF Freezer Alarm problem?

Could anyone help me to save my sanity. I purchashed an indesit UFAN400NF Freezer. Since the day i got this the temperature warning light and the alarm keep going off. I reset and this lasts for a few hours then off it goes again.

The food is staying frozen and there does not seem to be any problems with the temperature of the freezer.

I do believe this could be a problem with the temperature sensor being slightly disloged when transporting the appliance.
The only problem being, i don't know where to locate these on the freezer. Could anyone please advise where i can find these and where they should be so i can check to see if in correct position.

Thanks
