16.4.23 F91 (Refrigeration Cycle Abnormality)

Malfunction Decision Conditions

During cooling, compressor frequency = Fcmax.

During heating, compressor frequency > Fhrated.

During cooling and heating operation, running current: 0.65A < I < 1.65A.

During cooling, indoor intake - indoor pipe < 4°C

During heating, indoor pipe - indoor intake < 5°C

Multi Models Only

Gas shortage detection 1: A gas shortage is detected by checking the CT-detected input current value

and the compressor running frequency. During startup and operating of cooling and heating, input
current < 8.78/256 (A/Hz) x compressor running fre 0.25.

Gas shortage detection 2: A gas shortage is detected by checking the difference between indoor pipe

temperature and indoor intake air temperature during cooling and heating.

Malfunction Caused

Faulty indoor intake air or pipe temperature sensor

2/3 way valve closed

Refrigerant shortage (refrigerant leakage)

Clogged expansion valve or strainer

Faulty outdoor unit

Poor compression of compressor
