Fridge freezer not cooling any more, fault finding
July 23rd, 2019
Fridge freezer not cooling? This can be caused by a thermostat failure but that is rare to be honest. More likely the compressor is not running or not running properly for some reason.
- Compressor failure
- Compressor PTC
- Compressor relay
- Thermistor failure
If the fridge cools a little on a fridge freezer and the freezer section seems okay then it can also be a sign that there is either a blockage or a shortage of gas. Please note that a gas shortage will not manifest itself magically after a few years unless there has been physical damage to the pipework. Basically this is pretty much an experts area, but the causes are as follows in the main:
- Shortage of gas on appliances under a year old
- Blockage or choke in pipework
- Changeover valve faulty
- Compressor pumping weak (highly likely on older machines 8 years or more old)
See above as it’s pretty much the same as for a fridge.Punctured a hole while defrosting…
We see this a lot I’m afraid and it’s this simple, don’t ever go near the inside of a fridge with anything sharp and metal to defrost with as there is an extremely high probability that you will pierce a pipe in the fridge. This lets all the gas out, so no cooling, then because most people run them thinking it might be okay, oil gets dragged up from the compressor and chokes the pipework. Invariably the machine is a total write off.
If this is your problem, sorry but there’s not much that anyone can do to help you I’m afraid.
