Finding ice in the base of a freezer is a common fault. I’ve recently had to repair my own freezer with this problem and this article documents what I did to fix the fault. This issue can affect stand alone freezers, or the freezer section of a fridge-freezer.
Sometimes water may appear in the bottom of the fridge. This is usually caused when water created by automatic defrosting cannot run away through the hole in the channel at the back and it runs into the base of the fridge instead.
Many modern fridges, fridge freezers and freezers are noisy compared with older appliances. Strange gurgling sounds and the sound of moving liquid can be heard as the gases are pumped around the system. Some of the noises come from fans (which switch on and off) to blow cold air around. You should get used to the sounds that your appliance makes quite quickly although it is possible for some sounds to change as temperatures get hotter or colder in the room. So for example a different noise could start up in winter, or in summer as it works harder to keep things cool. Generally speaking though you should usually pay attention to new sounds in case they are an indication of a fault.
One cause of excessive frost and snow-like ice in a fridge or freezer can be a poorly fitting or damaged door seal. If the door seal becomes distorted or worn then the seal will start to allow warm moist air into the freezer or fridge. This can cause snowy ice to deposit around the shelves in a freezer or on the back wall of a fridge.
Help and advice by an engineer, on how refrigeration appliances can be adversely affected by the environment that they are placed in. If the temperature surrounding the appliance moves outside its climate rating specified by the manufacturer (Climate Classes for fridges, freezers and fridge-freezers) they can stop working.
