A method for the automated detection of leaks between the high and low-pressure sides of a refrigeration system is provided. A large pressure difference is created between the high pressure side and low-pressure side. By measuring and comparing system pressures at different times, the operational condition of valves which connect the high pressure side to the low-pressure side is accurately determined. By accurately determining that these valves are operating correctly, and in particular that no leaks exist in the valves, reports of false failures are prevented, while the reduction in the refrigeration system's capacity to heat or cool is prevented.
