Troubleshooting and Maintenance

Fault code system

Indoor unit fault codes: covering communication faults (such as E03: indoor remote control communication interruption, E04: indoor outdoor communication interruption), sensor faults (such as F01: TCJ sensor open/short circuit, F10: TA sensor fault), hardware faults (such as P10: indoor overflow, P12: DC fan fault), each code corresponds to a clear troubleshooting direction (such as checking line connections, sensor resistance, hardware components).

Outdoor unit fault codes: including communication faults (E06: indoor unit disconnection, E23: outdoor outdoor communication interruption), abnormal pressure/temperature (P03: high exhaust temperature, P20: high pressure protection activated), compressor faults (H01: compressor overcurrent, H02: compressor lock), which need to be checked in conjunction with the 7-segment display on the external unit interface board and manual steps.

Test run operation

Wired remote control (RBC-AMT series): Press and hold the 【 TEST 】 button for more than 4 seconds to enter the test mode, press 【 MODE 】 to switch between 'cooling/heating', and the test will automatically exit after 60 minutes. During this period, the temperature cannot be adjusted, and the fault detection will take effect normally.

Wireless remote control: After turning on, wait for 1-5 minutes (5 minutes for the first power on), press [ON/OFF] to start, select "cooling/heating" for [MODE], select "HIGH" for [FAN], activate the test through a specific temperature setting sequence (such as cooling: 62 ° F → 64 ° F → 62 ° F), and the indicator light flashes for 10 seconds before starting.

Regular maintenance checklist

Daily maintenance: Clean the filter screen weekly (standard filter screen can be washed with water), check the paper capacity indicator, check the remaining consumables (toner, toner cartridge) monthly, and confirm that the safety lock and certification functions are normal.

Quarterly maintenance: Clean the scanning platform and feeder rollers, check network connection stability, test IPsec and data encryption functions; Every year, professionals inspect the health of SED hard drives, calibrate sensors (TA/TC1/TC2), and check the operating status of environmental protection modes.
