Indesit Fridge Freezer keeps freezing up MODEL c239 (frost free)?

Had same. dont know if its caused by leaving door open but mine does it regularly. My cure was to remove the cover and defrost (with the help of a hairdrier) any ice. My current downfall is cover was so iced up when i removed earlier that its pulled some wires out of the plug which are left trailing.
Any chance anyone can help me with pinout, specifically on the middle row ?
email me robvox@hotmail.com if any info regards rob
