If your Samsung Heating System is showing an inverter current sensor error, check the EEPROM DATA and ensure the PCB is operating normally.
What to do if a gas leak error is detected in Samsung Heating System?
If your Samsung Heating System indicates a gas leak error, you should check the coolant charging status. Also, examine the indoor EVA sensor. Ensure the outdoor unit service valve is open and verify that the indoor/outdoor installation pipe and wiring are correctly installed.
How to fix [Inverter] total current error/ PFC over current error in Samsung Heating System?
If your Samsung Heating System is showing an inverter total current error or PFC over current error, begin by checking the input power. Next, verify the coolant charging status. Finally, ensure that the outdoor fan is operating normally.
How to troubleshoot outdoor fan 1 error on Samsung Heating System?
If your Samsung Heating System is showing an outdoor fan 1 error, you should check the input power connection status. Verify the connection status between the motor and outdoor unit PCB. Also, inspect the indoor/outdoor fuse.
How to fix [Inverter] compressor startup error in Samsung Heating System?
If you're experiencing a compressor startup error on your Samsung Heating System, check the compressor connection status. Also, check the resistance between different phases of the compressor.
How to troubleshoot indoor temperature sensor (open/short error) -Zone2 on Samsung Heating System?
If your Samsung Heating System displays an indoor temperature sensor (open/short error) for Zone2, check the indoor unit room temperature sensor and the indoor unit PCB connector CNS043 Terminal(B15/B16).
What to do if IPM is overheated in Samsung Heating System?
If the IPM is overheated in your Samsung Heating System, check the INVERTER PBA's temperature. Power off and cool down the INVERTER PBA, then restart the outdoor unit.
How to troubleshoot indoor temperature sensor (open/short error) -Zone1 on Samsung Heating System?
If your Samsung Heating System displays an indoor temperature sensor (open/short error) for Zone1, check the indoor unit room temperature sensor and the indoor unit PCB connector CNS043(White).
