14.4.16 F91 (Refrigeration Cycle Abnormality)

Malfunction Decision Conditions

•

During cooling, compressor frequency = Fcmax.

•

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

•

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

Malfunction Caused

•

Refrigerant

shortage

(refrigerant leakage)

•

Poor compression performance of compressor.

•

2/3 way valve closed.

•

Detection error due to faulty indoor intake air or indoor pipe temperature sensors.
