SiBE04-824 TroubleshootingService Diagnosis 1014.14 Discharge Pipe Temperature ControlRemoteControllerDisplayF3Method ofMalfunctionDetectionThe discharge pipe temperature control (stop, frequency drooping, etc.) is checked with thetemperature being detected by the discharge pipe thermistor.MalfunctionDecisionConditions25/35 class If a stop takes place 4 times successively due to abnormal discharge pipe temperature, thesystem will be shut down. If the temperature being detected by the discharge pipe thermistor rises above °C, thecompressor will stop. (The error is cleared when the temperature has dropped below°C.) The error counter will reset itself if this or any other error does not occur during the following60-minute compressor running time (total time).50 class If a stop takes place 6 times successively due to abnormal discharge pipe temperature, thesystem will be shut down. If the temperature being detected by the discharge pipe thermistor rises above °C, thecompressor will stop. (The error is cleared when the temperature has dropped below °C.) The error counter will reset itself if this or any other error does not occur during the following60-minute compressor running time (total time).SupposedCauses Refrigerant shortage Four way valve malfunctioning Discharge pipe thermistor defective(heat exchanger or outdoor air temperature thermistor defective) Outdoor unit PCB defective Water mixed in the local piping Electronic expansion valve defective Stop valve defectiveStop temperatures(1) above 45Hz (rising), above 40Hz (dropping) 110 97(2) 30~45Hz (rising), 25~40Hz (dropping) 105 92(3) below 30Hz (rising), below 25Hz (dropping) 99 8650 class11095
