The most frequently asked questions about refrigeration, including frost free fridges, freezers and fridge freezers
Several things can cause this.
One of the common reasons is someone has accidently left the door slighlty open. This will cause moisture filled warm air to be 'sucked' in to the freezer compartment, which will then freeze, quickly filling the freezer with lots of ice. The only way to remedy this is a complete defrost. Empty the freezer and fridge (if a fridge/freezer) switch the unit off at the mains and leave for 48 hours with both doors open. Periodically mop up any excess water in the freezer and check the tray on top of the compressor (big black thing) at the bottom rear of the appliance.
If when you switch back on you find that ice builds up fairly quickly you will need to phone for an engineer as there will be a fault. Please ensure whoever you book the call with is aware that the unit is frost free as they a different ball game than standard refrigeration.

Firstly the term frost-free only applies to freezers or the freezer section of a fridge/freezer.
What it basically means is that ice should not form around your food and should never need defrosting. This is achieved by a fan circulating the cold air rather than the shelves themselves freezing. The 'freezing' is actually taking place behind the cover at the rear of the inside of the freezer compartment. The ice is defrosted periodically by a heater switched on and off by a timer, any excess water is than chanelled out via a tube to the tray on top of the compressor, where it evaporates.
Automatic defrost applies to the fridge section of a fridge/freezer or a larder fridge. What it means is you will never have to manually defrost it ! This is achieved by having no frozen section in the compartment. The cooling is done by freezing a panel or the rear of the fridge itself, when the fridge is cold enough, the thermostat will switch the compressor off and any ice will turn to water. The water will then run into a channel where it will be carried out of the fridge into a tray at the rear, where it evaporates.
If your fridge is of the 'larder' type, i.e. it has no ice box inside the main fridge section or it is the fridge section of a fridge freezer, the hole at the rear will be blocked. This hole is for the automatic defrost function of the fridge (see other section here). You will need to unblock it with something. Sometimes a tool for this is provided by the manufacturer, if not refer to your user manual.
Yes ! They will be able to do this for you. But, as it is a fairly simple job to do, you may well object to being charged a standard fee for possibly only five minutes work. If you have an extended warranty many insurers will not cover this sort of work as they will consider this to be within the customers scope and does not require an engineer, as always check your policy details first.
