Fridge And Freezer Forum

I have a Zanussi Zi918/12KA Fridge-Freezer several years old: after defrost about a month ago a loud gurgling noise is coming from inside the fridge and freezer, and the compressor is running continuously. Have replaced the thermostat but it made no difference. the freezer is very cold and the fridge slowly reaches -8 deg C.
The new thermostat is set at minimum (1) but does not seem to switch off the compressor, suggesting the new thermostat is faulty....?
In any case the gurgling is very annoying - can anything be done about it?

The compressor may be at fault not pumping or the appliance is low on gas it may have a small leak.

This is a system fault not a thermostat fault.

Thanks. Could you explain why the compressor is not switched off by the thermostat when it reaches 0degC or thereabouts, as the thermostat seems to be the only thing that controls the compressor?
Is there any way of detecting a leak and refilling, or is it a write-off, which is an expensive loss after only a few years service?

It will not be getting cold enough where the thermostat senses the temperature so the stat will not turn of the compressor.

To test if it has lost the gas or if the compressor is faulty is not a DIY job and can be expensive depending on the fault.
