Yes I did mean the black thing at the bottom on the back. Have just tried again and the same happens but when the compressor cuts out all the lights go out on the temp display and then come on again a few seconds later.
Does this confirm your suspicions?
will try that. Assuming that this does nothing to solve the problem, is this something I can sort out myself and how much is it likely to cost. Just wondering if a repair is feasible or if I am better off replacing the fridge altogether.
Thank you for your help
