My Indesit c239nf had not been getting cold for months, the red lamp was always flashing and I sat with a hairdryer (though dangerous and not recommended) melting ice that was gathering in the top of the freezer compartment on a weekly basis. I rang a repairer who told me I needed new door seals and it was not cost effective to do, so I looked at reviews on various fridge freezers. All seemed to have their problems. In a last ditch attempt, I removed all of the shelves then the cover at the back of the freezer compartment. Behind there was only a wire type of connection to the back of the freezer, nothing more to see and that seemed in place. I then removed the 2 screws from the box housing the wires on the roof of the top shelf of the freezer. This should have come away immediately as there were only 2 screws holding it. However, the back of the 'box' would not move. I sat with the hairdryer pointed at the back of the box and melted more ice until the whole of the box came away. I then found a massive block of ice covering the back of this compartment, covering all the 'workings'. I continued melting this block of ice until it was all gone. It took best part of an hour. I could see the fan and when the hairdryer was pointed at the fan the fan spun round so there didn't seem to be any problem with that. I could see the wires going from the top left hand side of the compartment going to the back of the freezer. None were loose. When the ice was fully gone, I replaced the box over the wiring and workings. I then replaced the cover from the back wall. I left the freezer to settle for an hour more but I couldn't wait any longer as I had food to put back in. After switching it back on at the wall it took about 10 mins ( as says in the handbook) for the motor to come on. The red lamp was still flashing but I knew this was because the fridge freezer was just starting again from scratch. Anyway, by the next day, I could hear the motor switching on and off and the fan turning, which it hadn't done for months. The final result is that after 2 weeks the FF is still working perfectly. Everything in the freezer is now deep frozen. With hindsight, after 5 years of no problems except for broken freezer door fronts, it would have required some maintenance. So, if you have one of these models, try this first before ditching. It could be that this is the answer to the same problem on other makes and models too. Have a go, there is nothing to lose, it could work or you would have needed to buy another one anyway. I hope this helps.
