What is E4 Error in Samsung Air Conditioner?

The E4 error is one of the error codes that can appear on the display of your Samsung air conditioner. It usually indicates an overheating problem or a malfunction of the temperature sensor. This error can prevent your appliance from working properly, affecting its performance and the comfort of your home.

In detail:

• E4-01 : Lack of refrigerant during cooling mode. In this case, you can try to reset the system using the K1 button and check the cooling system connections for potential leaks or blockages in the circuit and pipes.
• E4-04 : overload of the outdoor unit and consequent stop of the compressor.
• E4-16: Need to clean the indoor unit filter. It is important to clean and sanitize the indoor unit and remove any external blockages.
• E4-19 : An error has been detected in the outdoor unit. It is necessary to contact a technician to carry out an inspection and replace any damaged components.
• E4-22 : the code indicates that the external valve has remained closed. It is necessary to request the intervention of an authorized technician to reset the device.
• E4-40: The appliance overheats (the temperature is much higher than 30 degrees in heating mode). It is recommended to turn off the air conditioner and wait for it to cool down.
• E4-41 : temperature too low (below 5 degrees centigrade).
• E4-58 : ventilation system problem.
• E4-60 : Incorrect connection between the device and the power cord.
• E4-61 : indicates a malfunction in the outdoor unit, probably in the compressor, requiring the intervention of an authorised technician for repair or replacement.
• E4-62 : Compressor trips due to input current limit exceeded.
• E4-63 : the compressor trips due to exceeding the OLP temperature limit.
• E4-64 : Current overload protection.
• E4-65 : compressor overload protection.
• E4-66 : voltage fault in the intermediate circuit (voltage less than 150 V or greater than 410 V).
• E4-67 : compressor rotation error.
• E4-68 : Current sensor error. Need to check and replace if necessary.
• E4-69 : Intermediate circuit voltage sensor error. Check and replace if necessary.
• E4-70 : Compressor overload protection. Check refrigerant charge and heat exchangers.
• E4-71 : EPROM memory error. Check and replace if necessary.
• E4-72 : Problem in the electronic board of the outdoor unit. You need to contact Samsung customer service for assistance from a specialized technician.

Common Causes of E4 Error

The most common causes of the E4 error include:

• Airflow Obstructions : Blocked or dirty air filters can cause heat buildup.
• Malfunctioning temperature sensor : If the sensor is damaged or poorly positioned, it may not detect the temperature properly.
• Electrical Problems : Power surges or problems with the power supply may cause temporary malfunctions.
• Unit Overheating: The air conditioner may go into E4 error due to overheating, which can be caused by poor ventilation or blockage in the airflow.
• Blockage in Air Filters: Dirty or clogged filters can restrict airflow, causing the internal temperature to rise and the error code to activate.
• Compressor Problems: A faulty or ineffective performance of the compressor can lead to increased internal temperatures.
• Clogged Cooling Circuits : A buildup of dust or debris in the air vents or ducts can limit cooling and result in an E4 error.

Steps to Fix E4 Error in Your Samsung Air Conditioner

Here are some steps you can follow to try to resolve the error yourself:

• Samsung Air Conditioner Reset Procedure:

1. Turn off the unit : Before proceeding, turn off the air conditioner and unplug it from the outlet.

2. Check the air filters : Make sure the filters are clean. If they are dirty, remove them and clean them with water and mild soap. After the filters are completely dry, reassemble them.

3. Inspect the temperature sensor : Make sure the sensor is seated properly and has no visible damage.

4. Start the unit : Replug the air conditioner and turn it on to see if the error persists.

Preventive Maintenance to Avoid E4 Error

Here are some tips for proper maintenance of your Samsung air conditioner:

• Regular filter check : Cleaning the filters at least once a month during periods of intensive use prevents dust accumulation.
• Annual inspection by a technician : A professional checkup can detect potential problems before they cause malfunctions.

If the error persists after following the steps above, it may be time to contact a professional technician.

Other common errors in Samsung air conditioners

In addition to the E4 error , Samsung air conditioners can suffer from a number of other common errors that can affect their performance. One of these is the E1 error , which is usually indicative of a problem with the room temperature sensor, which can result in ineffective operation in controlling the internal temperature.

The E2 error can indicate a malfunction in the evaporator coil sensor, which can lead to defrosting problems or poor cooling efficiency. Another common error is the E3 , which often indicates a fault in the outside temperature sensor, causing an inaccurate outside temperature measurement and affecting the heating or cooling capacity of the unit.

The E5 error is usually associated with faulty communication between the indoor and outdoor units, which can result in incorrect synchronization of the heating and cooling functions. The CF error , on the other hand, appears when the indoor unit's filter needs cleaning, signaling that it is time for maintenance to ensure adequate airflow. Finally, the E6 error can indicate a pressure problem in the refrigeration circuit, which could be caused by a refrigerant leak or a blockage in the system.

These errors, although common, can be addressed with proper maintenance and, when necessary, with the help of a specialized technician to ensure the full functioning of the air conditioner.
