A refrigeration system (10) has a compressor (12), condensor (13) and evaporator (14) connected in a refrigeration circuit. A controller (16) has probes (19, 20) for sensing the temperatures of the evaporator (14) and condensor (13) respectively. The controller controls the operation of the compressor, and hence the refrigeration circuit, so that the compressor does not start unless the evaporator temperature is above a preselected value (Tstart), and stops the compressor if the evaporator temperature falls below Tdisable. An alarm (21) is activated if the condensor temperature rises above Talarm, and the controller (16) stops the compressor (12) if the condensor temperature rises above a higher temperature Tshutdown.
