A refrigerant leak detection system includes a leak sensor module for sensing leaked refrigerant and a universal connector. The universal connector is configured as a junction for connecting an AC voltage source with the leak sensor module and an evaporator fan of a refrigerated case. The universal connector is configured to be operable for selectively supplying AC voltage from the AC voltage source to the evaporator fan, or to the leak sensor module, or to both the evaporator fan and the leak sensor module. When the leak sensor module is activated to conduct leak testing, the AC voltage from the AC voltage source to the evaporator fan is interrupted by the universal connector to thereby turn OFF the evaporator fan and facilitate detection of any leaked refrigerant.
