On anything other than the highest setting the compressor doesn't come on at all.
Replaced the thermostat but the fault is still the same - 'only cools when the thermostat is set at maximum' - see my previous comments.
You will understand that I am reluctant to spend another £38.00 unless I can be absolutely sure this the fault.
Spend another £38 on what John? If you have bought a thermostat and it is faulty then just send it back for a replacement.
Replaced thermostat with a new one and the fault is still the same. Decided to get an engineer to visit but he said he won't touch the fridge as I have carried out the repair.
I now find myself with a fridge that doesn't work and no way of getting it repaired.
The weaknesses of diagnosis though the internet is all too obvious....
Followed your instructions and the fridge did come on this time but only ran for 3 minutes and then switched off.
When it came on the compressor became warm to the touch (not hot). The thin pipe is perhaps slightly warmer than the compressor. Large pipe is cool but not cold. The cycle lasts about 3 minutes and then the compressor shuts off again.
The temperature in the fridge is cool rather than cold - back wall is wet. The compressor cycle is the same - short duration and then stays off for a while. Pipes: thin, warm and thick cool. Compressor is warm to the touch.
No, but if you think it might help I will get one tomorrow?
