– 27 – SM830079 10. PR OCESSES AND FUNCTIONS (1) Room Temperature Control The Unit adjusts room temperature by turning the outdoor unit’s compressor ON and OFF.
– 28 – SM830079 10. PROCESSES AND FUNCTIONS (2) Freeze Prevention Freeze Prevention keeps the indoor heat exchange coil from freezing. Freezing reduces the efficiency of the unit, and frost buildup on the coil blocks cool air circulation from the indoor unit’s fan.
– 29 – SM830079 10. PR OCESSES AND FUNCTIONS (4) Outdoor Fan Speed Control (CL1852) Low ambient fan speed control • This function protects the compressor from being damaged due to flowback of the liquid refrigerant to the compressor when the outdoor temperature is very low.

SER VICE PROCEDURES (1) Troubleshooting 1) Check before and after Troubleshooting Many problems may happen because of wiring or power supply problems, so you should check these areas first. Problems here can cause false results in some of the other tests, and so should be corrected first.
– 31 – SM830079 11. SER VICE PR OCEDURES 2) Air Conditioner does not Operate 1 1 1 1 1 Circuit breaker trips (or fuse blows). (a) When the circuit breaker is set to ON, it is tripped soon. • There is a possibility of ground fault. • Check insulation resistance.
– 32 – SM830079 11. SER VICE PROCEDURES (b) Circuit breaker trips in several minutes after turning the air conditioner on. • There is a possibility of short circuit. 2 2 2 2 2 Neither indoor unit nor outdoor unit runs. A. Power is not supplied 0615_X_S • Check power supply.
– 33 – SM830079 11. SER VICE PR OCEDURES C. Check “Operation selector” switch in the indoor unit. D. Transformer in indoor unit. E. Check. auxiliary relay. 0617_X_S • Has “Operation selector” switch been set to ON position ? YES Set “Operation selector” switch to ON.
– 34 – SM830079 11. SER VICE PROCEDURES G. Check fuse on the P.C.B. Ass’y in the indoor unit. F. Check indoor fan motor thermal protector (49FMI) • Disconnect the socket from 9P (WHT) connector. • Check the continuity between No. 8 and No.9 poles of the 9P socket.
– 35 – SM830079 11. SER VICE PR OCEDURES 3) Outdoor Unit does not Run. A. Check COOL / FAN selector switch in the remote control unit. B.
