Common Error Codes on Samsung Air Conditioners
The common error codes on Samsung air conditioners, whether inverter or non-inverter, include the following:
+ CF Error Code: Reminder to clean the filter or reset. Clean or replace the internal filters of the indoor unit.
+ Cl Error Code: Automatic cleaning reminder (indoor unit emits odor). Operate the automatic cleaning function to eliminate odors.
+ Error code dF: Automatic defrost function activates due to humidity, snow, or dew buildup on the outdoor unit, reducing heating efficiency. To resolve this, turn off the heating mode.
+ Air conditioner runs for 3 – 10 seconds then automatically shuts off: This is a fault in the evaporator circuit.
+ Air conditioner leaking water: Incorrectly installed pipes, reversed slope, or improper water drainage. To fix this, reinstall the pipes.
+ Air conditioner turns on but doesn't run: No power supply, control not receiving signals. Check the power supply.
+ Air conditioner runs but doesn't cool: Insufficient gas, dirty filter. Proceed to check the gas pipeline or recharge, clean the filter.

+ Error codes Er E1 or E1: Room temperature sensor malfunction.
+ Error codes E2, Er-E5, and Er – 05: Fault in the temperature sensor of the indoor unit.
+ Error codes E3 and E3-01: Fault in the indoor fan motor or fan signal.
+ Error code E5: Short circuit in the heat exchange sensor of the indoor unit, open heat exchange sensor. Check the startup of the indoor heat exchange sensor (sensor replacement may be required).
+ Error codes E6 and Er-06: Short circuit in the heat exchange sensor of the outdoor unit, open heat exchange sensor. Check the startup of the outdoor heat exchange sensor (sensor replacement may be required).
+ Error code E7: Short circuit in the temperature sensor of the heat exchanger unit, open temperature sensor of the heat exchanger unit. Check the startup of the temperature sensor of the heat exchanger unit (sensor replacement may be required).
+ Error code Er-01: Signal fault between the outdoor and indoor units.
+ Error code Er-11: Abnormal current increase in the air conditioner.
+ Error codes Er-12, Er-13: Temperature increase fault.
+ Error code Er-14: Variable frequency main board fault.
+ Error code Er-15: Fault in the outdoor unit heat dissipation system, possibly due to overheating of the outdoor unit fan.
+ Error code Er-10: Compressor fault, control board malfunction.
+ Error code Er-E6: Temperature sensor malfunction.
+ Error code Er-31: Fault in the outdoor temperature sensor.
+ Error codes Er-32, Er-33: Fault in the exhaust air temperature sensor.
+ Error code Er-17: Fault in two components on the inverter main board of the outdoor unit.
+ Error codes Er-36, Er-37: Fault in the heat dissipation sensor of the main board.

+ Error code E1 62: Main control board malfunction.
+ Error code E1 63: Error code setting option.
+ Error code E1 85: Fault due to power cable or signal line.
+ Error code E2 01: Incompatible indoor unit fault.
+ Error code E2 03: Signal fault between the 2 boards of the outdoor unit.
+ Error code E2 21: Fault in the outdoor unit wind sensor.
+ Error codes E2 37, 46: Fault in the outdoor unit gas sensor.
+ Error codes E2 51, 61, 60: Block sensor fault.
+ Error code E2 59: Fault in the outdoor unit.
+ Error code E3 30: Block temperature sensor fault.
+ Error code E4 01: Heat exchange coil in the indoor unit stops heating.
+ Error code E4 04: Outdoor unit overload and compressor stops (heating mode protection control).
+ To check Samsung air conditioner errors, observe the display screen to see which error code is shown, such as E1, Er-01, E4 01, CF… For some models without a display screen on the indoor unit, warnings will be indicated by flashing different colored buttons on the outdoor unit's main board.
+ Most Samsung air conditioner models are equipped with self-diagnosis and error display functions, allowing you to easily detect errors and find the causes for effective troubleshooting. Some Samsung AC models you can consider are: Samsung Inverter 1.5 HP AR13TYHYCWKNSV; Samsung Inverter 1 HP AR09TYHQASINSV; Samsung Inverter 1 HP AR10TYHYCWKNSV; Samsung Inverter 2 HP AR18TYHYCWKNSV; Samsung Inverter 1.5 HP AR13TYGCDWKNSV…
