To maximise the life of your appliance, here are a few tips:

the most common problems

Heating problem

As paradoxical as it may seem, in order to cool down, it must first heat up. During normal operation, the tubes at the back of the appliance must be hot (over 60 °C); this means that the ammonia is indeed in a gaseous state. If the tubes are cold, there is no need to go further in the diagnosis, you have a heating problem.

Regulation problem

If the appliance still does not work once the heating part has been checked, you can check the regulation elements. The thermostat, the automatic defrosting clock for older models, or, for the newer models, the electronic board that performs both these functions. All three of these can act as a circuit breaker if necessary and cut off the electric supply to your fridge.

Problem with the compressor

However, most recent appliances use a compressor for most models. The compressor is the main cause of the noise we now associate with a fridge. Compressors are complex and difficult to repair by yourself. In the event of a malfunction, it is not uncommon to hear abnormal noises coming from the appliance.


Most recent fridges display fault codes, which will make it easier for you to identify the problem you are encountering. The operating instructions for your appliance contain all the explanations necessary for interpreting them.
