I have an old Phoenix bottle cooler that is only cooling down to about 18 degrees.
I can hear the compressor working all the time so I assume the only problem can be either a worn compressor or lack of gas. Can anyone please advise on what steps I can take to isolate what is wrong and how to repair it?
I understand that the only components are the compressor and thermostat and they are apparently generic versions, but would welcome any confirmation of that.
Thank you.
