Error code table for Daikin inverter air conditioners - H error code
The H error codes of Daikin inverter air conditioners include:
+ H7 error code: Abnormal signal from the outdoor fan motor. Possible causes include faults in the outdoor fan, faulty Inverter fan board, or faulty signal transmission wire.
+ H9 error code: Fault in the outside air temperature sensor (R1T) or the outdoor unit board. Check the outdoor air temperature sensor for any faults.
Error code table for Daikin inverter air conditioners - J error code
The error code table for Daikin inverter air conditioners - J error code includes the following errors:
+ J2 error code: Fault in the current sensor head or the outdoor unit board. Check the current sensor for any faults.
+ J3 error code: Fault in the temperature sensor head of the gas pipe (R31T~R33T). Specifically, this could be due to a fault in the temperature sensor of the discharge pipe, outdoor unit board, or the connection of the temperature sensor.
+ J5 error code: Fault in the temperature sensor head (R2T) of the gas return pipe. Specifically, this could be due to a fault in the temperature sensor of the suction pipe, outdoor unit board, or the connection of the temperature sensor.
+ J9 error code: Fault in the supercooling degree sensor (R5T); fault in the supercooling degree sensor R5T; fault in the outdoor unit board.
+ Error code JA: Issue at the pressure sensor head of the gas supply pipe; high pressure sensor fault; outdoor unit board fault; temperature sensor connection fault or incorrect position.
+ Error code JC: Issue at the pressure sensor head of the gas return pipe; low pressure sensor fault; outdoor unit board fault; temperature sensor connection fault or incorrect position.
Error code table for Daikin inverter air conditioners - L error code
The L error codes for Daikin inverter air conditioners include the following errors:
+ L4 error code: Issue due to increased heat sink temperature of the inverter. Specifically, this could be due to a high heat sink temperature (≥93°C); circuit board fault; heat sink temperature sensor fault.
+ L5 error code: Abnormal inverter compressor. Specifically, this could be due to a faulty inverter compressor coil; compressor start-up fault; faulty Inverter board.
+ Error code L8: Abnormality in the inverter current. Specifically, this could be due to overload of the Inverter compressor; Inverter board fault; faulty compressor coil (electrical leakage, locked rotor, etc.);
+ Error code L9: Issue during the inverter compressor start-up. Possible causes include Inverter compressor fault; incorrect connection wires (U, V, W, N); failure to ensure high and low pressure differential during start-up; closed shut-off valve; Inverter board fault.
+ Error code LC: Issue with the signal between the Inverter board and the control board. Specific causes include connection issues between the Inverter board and the outdoor control board; outdoor control board fault; Inverter board fault; noise filter fault; Inverter fan fault; incorrect fan connection; compressor fault; fan motor fault.
