PURPOSE: An abnormality sensor of a refrigerant cycle is provided to repair an air conditioner easily by comparing the current indoor temperature, outdoor temperature, input voltage changes and indoor heat exchanger temperature with pre-saved data and displaying abnormality in mounting and of a refrigerant cycle. CONSTITUTION: An abnormality sensor of a refrigerant cycle includes: an indoor temperature sensor(10); an outdoor temperature sensor(20); an indoor heat exchanger temperature sensor(30); an input voltage change sensor(40); a refrigerant display unit(50) displaying abnormality of refrigerant to a user according to an input control signal; and a control unit(60) saving reference condition data including indoor temperature, outdoor temperature, input voltage change and indoor heat exchanger temperature depending on capacity and overload of an air conditioner, deciding abnormality of refrigerant by comparison between the current condition data and the reference data, and displaying abnormality of refrigerant to a user through the refrigerant display unit. The current condition data are compared with the reference data, and abnormality of refrigerant is displayed through the refrigerant display unit all the time while an air conditioner is run. Therefore, the user checks troubles of the air conditioner easily and repairs the air conditioner promptly.
