Refrigerator doesn t get cold

If your refrigerator is frost free and been running for a year or two then here is the solution.
Why would you need to defrost a frost-free freezer? Because they do sometimes get frosted up! This is especially common if the door gets left open for long periods without being noticed, then shut again, thereby trapping lots of moist air in the freezer, which can only come out as frost. The problem is that if their defrosting cycles don't manage to cure their problems they get frosted up at the back, out of sight. If your freezer seems to be struggling to keep things frozen but is otherwise working normally you should consider defrosting it before concluding it is broken.

I have found the best way to defrost my not quite frost free fridge-freezer is to empty the freezer compartment contents into the fridge and switch it off overnight, leaving the fridge door shut and the freezer door open. By stacking all the frozen food together as tightly as possible, ideally wrapped in something to help insulate them (such as newspapers) they stay cold for a long time. In the morning I get in my scruffy clothes and wipe up the puddles caused by the visible frost in the freezer and any puddles formed underneath the appliance. However this is only half the story. To ensure all the frosting has been removed from the hidden parts of the appliance I get my hair dryer and blast warm air into all appropriate crevices from inside the appliance and from behind it.
