Noise from fridges and freezers
All electrical appliances make some sort of noise and you soon attune to the various electronic noises you hear around the house. It could be that you have just taken delivery of a new appliance, be it a stand-alone fridge or freezer, or an American-style fridge freezer which you may find much noisier than your previous equipment.
It is probably a good idea to try to adjust to the new noise in your home and, in most cases, you will stop noticing it – a bit like the railway running at the end of your garden which you stop hearing altogether. However, it is never a good idea to have any kind or fridge or freezer in an area where people might be sleeping, as the noise will almost certainly disturb or interrupt sleep.
Obviously some makes and models are much louder than others and if you do find it too obtrusive, this is something you should take up with your retailer. It would be better if you select a different model as whatever the retailer suggests you try to resolve the issue is probably never going to work for you.
When a fridge freezer is connected and working, the compressor or motor will be running up to 60% of the time, but if you have a frost free model it can run for up to 80% of the time.
Some of the better quality fridge freezers will now have linear compressors, and were introduced to reduce energy consumption, but the knock on effect of them is that they seem to run quieter – a plus plus, but of course these linear compressors are generally fitted to the more expensive appliances.
Since the discovery that the old refrigerant gasses were having a detrimental effect on the environment, we have now moved on to a generally acceptable gas that goes by the name of R600.
The downside of this gas is there have been more complaints about cracking and groaning noises. It was thought this was due to expansion and contraction within the refrigerator unit. Unfortunately, the cause of this noise has not been resolved and if you are unlucky to have a creaking fridge, there is unlikely to be a cure for the noise.
Frost Free and American-style fridge freezers
If you notice a whirring noise, some describe it as a scraping sound, it is generally caused by by a build up of ice around the fan. There could be more than one fan in your appliance, depending on the make and model.
What you need to do is to try and find out what is causing the problem – it could be our old friend condensation. If you have overpacked either your fridge or freezer, you could be interrupting the airflow, resulting in a build up of condensation. Easily resolved by repacking, ensuring sufficient space is left for the air to flow around the cabinet. Another cause of condensation can be from keeping large quantities of fresh fruit and vegetables, surprisingly enough.
However, this noise can also be caused by a faulty fan motor and is worth investigating, as the problem can be caused by the fan motor icing up.
If you have a water and ice dispenser module on the outside of your American-style fridge freezer, this can intermittently make more noise than a normal fridge freezer, especially when the ice-maker is filling up. Once you get used to this noise though it should not be a problem once you understand what the sound is, as it can certainly make you jump when you are first aware of it.
