I would agree with maydup and VHG.
If you are going to leave it on, then fill it with carriers of newspaper or bubble wrap.
We close our holiday home up from dec til feb, turn off fridge/freezer, defrost it, make sure it is dry, leave it open and put some newspaper under the front of it, just in case.
The main thing is to leave it open or you will come back to a mouldy smelly fridge.
ARe you going anwhere nice always seems such a stupid question, so where are you off to?
