Probleemoplossing
Praktische tips om de meest voorkomende problemen met Fujitsu Airstage AJYA90LALH op te lossen.
Oorzaak: Water drainage path is blocked
Check drainage hose and clear any blockage by pouring water through it
Oorzaak: Low or high refrigerant pressure
Check high and low pressure values with pressure gauge. Normal cooling pressure approximately 0.8 MPa, heating pressure approximately 3.0 MPa
Oorzaak: Indoor or outdoor unit fans not running
Check visually that indoor and outdoor unit fans are operating
Oorzaak: Compressor not starting after indoor unit activation
Check operating sound to confirm compressor operation after indoor unit starts
Oorzaak: Temperature difference between inlet and outlet incorrect
Measure inlet and outlet temperatures. Normal temperature difference should be approximately 10 degrees
Oorzaak: Error not displayed or no error segment LED indicator
Check 7 segment LED indicator for error code display
Oorzaak: Operating mode not set correctly
Verify system is in correct mode: CL (Cooling), Ht (Heating), oF (Oil recovery), dF (Defrosting), PC (Peak cut), Ln (Low noise), Sn (Snowfall mode)
