In addition, while the replacement job is straightforward, it may be more than some people are willing to take on at this time.

So continue reading to find out what the refrigerator error code 40 e means for your icebox fan and how to resolve it.

Troubleshooting: Issues on Samsung Refrigerator code 40 e

Freezer defrost malfunction.Replace the defrost heater, defrost thermostat, or defrost timer.
Ice maker fan malfunction.Replace the ice maker fan motor or the ice maker fan sensor.
Ice buildup in the freezer.Clear the ice buildup from the freezer.
Bad control board.Replace the control board.
Call a technician.Contact a qualified technician to inspect the refrigerator.


It can be found in models that are side-by-side. It is caused by a malfunction of the ice machine fan, which is responsible for cooling the system because it is equipped with air cooling.

Typically, the cooler removes heat from the refrigerant pipes and prevents the unit from overheating to the point where it causes it to fail.

As a result, if the error code 40E appears on the screen, the cause must be determined by inspecting the fan and the elements associated with it. For example, a code like this could be used in conjunction with:

1E (it indicates a failure of the defrost sensor in the freezer); 21E (it indicates a failure of the freezer cooler); 24E (it indicates a failure of the defrost sensor in the freezer) (it indicates improper defrosting of the freezer).

An icebox fan error will be displayed as code 40 e on the computer screen. This indicates that the fan inside the freezer, which is typically found in a dual door model, is having difficulties cooling or functioning.

If the fan is not working, it could be because it is frozen to the other components of the freezer or because the wiring is faulty. As is always the case, allowing the machine to thaw is the best place to begin.

1. Before you begin working on the Samsung refrigerator, make sure it is unplugged.

It is important to check that the refrigerator is not plugged in before proceeding with the 40 e error code investigation and diagnosis. When there is insufficient power, the person working on the machine will be protected from any shocks.

It is important to remember that mixing water and electricity can result in death if they are not handled properly. Unplug the device to ensure the safety of yourself and others.

During a power outage, you have the perfect opportunity to conduct some inspections of the machinery.

In order to prevent food from spoiling, you must first remove it from the refrigerator and place it in coolers; if there is any standing water or wet surfaces, you must take a towel and wipe them all down before continuing.

2. Remove the pan from the machine and set it aside.

Take the time to remove the fan from the back of the freezer now that you have a dry and unpowered workspace. When you look at it, there are usually four bolts that are facing you as you examine it.

These bolts are responsible for holding the fan in place at the back of the machine. Remove them and make sure that the fan does not fall down into the freezer’s walls while you are doing so.

When it comes to fan placement, Samsung refrigerators frequently have a fan that is located inside the freezer, making removal much easier than with older models, which required removing the interior walls to access the fan location.

Keep an eye out for broken or punctured walls and packaging on the inside of the freezer if you have to take the walls and packaging out.

3. Before refilling the freezer, install the fan and run a test run.

The fan should be packaged in a single box-like structure, similar to what you would find on a computer fan. Because they keep the parts compact and closed off, they prevent any damage from occurring from the user’s actions.

Because the fan is self-contained, you will have to purchase a new one if it breaks down while in use. Please refrain from poking around in the boxes unless you have been authorized to do so.

It is possible that opening a cooling fan will result in the destruction of valuable electronic components on the inside as well as small pipes connected to cooling agents.

Consequently, if you plan to remove the fan, make sure to remove all of the parts that lead to it. Making repairs on your own can either save you time or cost you a lot of money. Always conduct thorough research before entering a situation blindly.

4. Restart the refrigerator and get back to your normal routine.

You can now turn on the machine now that the fan has been installed and all of the pieces have been reassembled. Once it has reached operating speed, you can begin to re-insert pieces of food into it.

It is important not to overfill the refrigerator right away because this will interfere with its ability to cool. It’s best to let it sit for an hour or two before you start refilling it with more water.

Don’t treat your refrigerator as if it were a machine that didn’t require any maintenance. Instead, you should create a schedule that will keep your food safe and your refrigerator running like a well-oiled machine all day long.

Whenever you hear the fan sluggishly turning or notice condensation on your food, take a moment to inspect. A small amount of time invested now could save you a lot of money in the long run.


In side-by-side refrigerators, a cooler is located behind the freezer’s wall, which is responsible for blowing the tubes with the refrigerant from the ice machine. A defrosting unit is conveniently located close by.

The failure of any component of this system causes a chain reaction to occur. As a result, the error code 40E appears on the screen of the Samsung refrigerator, indicating that the blades of the refrigerator have been blocked by frozen ice. Other possible causes of the error, on the other hand, cannot be ruled out.

1. Defrosting sensor that has been damaged

It occurs as a result of the carelessness with which the equipment is handled. In particular, overcrowding the freezer with products causes them to adhere to the walls and shelves. Furthermore, because the defrost sensor is located just inside the upper part of the vehicle, jerking is the most common cause of sensor failure.

Furthermore, it is possible that both the device itself and the wires leading to it will be damaged.

The defrost function is being abused in this situation. The ice machine’s fan is covered with ice, resulting in the appearance of error 40E.

Unplugging the refrigerator from the outlet and manually defrosting the chamber with a stream of warm air will effectively eliminate the problem. Take off the back cover and inspect the sensor for damage after it has been removed from the ice. Wires that have been disconnected must be connected, and a sensor that has been damaged must be replaced.

2. The impeller has been seized.

Another reason for the appearance of error code 40E on the display is the inability to rotate the blades smoothly. It is possible that they are clogged, blocked, or unbalanced.

Each situation necessitates a different approach to the problem: removing any adhering dirt and debris from the subunit; removing any foreign objects and pieces of ice that are preventing the cooler from turning; twisting the central part of the impeller and securing it firmly into place

3. The fan motor has failed.

The shaft on which the blades are mounted is rotated by a small electric motor. It fails when the air supply to the refrigerant pipes is interrupted, resulting in an issue with the ice machine and, as a result, the error 40E is displayed on the screen.

An electronic multimeter is used to evaluate the performance of the electric motor. On the mainboard, the voltage on cn76 1 and cn76 2 should be between 7 V and 12 V at all times. If the temperature is normal, the cooler will need to be replaced. A new one will set you back between $ 50 and $ $60.

4. Contacts that are not working properly

There are wires connecting the fan to the control board, and any fault in the wiring causes the circuit to be interrupted, preventing the signal from flowing. Even flickering currents (intermittent due to a poor connection between the ends) can cause the fan to stop and result in error code 40E being displayed.

The solution is to solder or twist the circuit board to restore the normal voltage supply. Alternatively, if the break is significant, the entire cable will be replaced.

5. Control board that is not working properly

The failure of the main PCB, which results in the cooler’s inability to operate properly and the appearance of error 40E, may be the cause of the error. In order to test it, you must measure the voltage on cn76 1 and cn76 2 while the fan is operating in forced mode.

  1. Hold down the Energy Saver and Power Cool buttons for 8 – 12 seconds to maximize efficiency.
  2. After the sonic signal has been received, press the Power Freeze button. The blades will begin to rotate at their fastest possible speed.
  3. Take a reading of the voltage.
  4. To slow down and repeat the test, press the Power Freeze button a second time.

This will assist in determining the exact status of the board. In order for it to function, it must be able to transmit current to the cooler of the ice machine. Furthermore, if the self-diagnosis system is not functioning properly, it may display incorrect codes.

Consequently, the samsung e40 error appears out of nowhere for no apparent reason. What is the best course of action? Soldering parts, restoring tracks, or replacing the entire microcircuit chip are all possible options.

Our Final Thoughts 40e Error Code Samsung Refrigerator

The fan in the freezer box of your Samsung refrigerator is likely to be the source of the error code 40 e. Dual door models are subjected to this code on a much more frequent basis than drawer and single-door models. Although replacing the fan may be difficult for a novice, hiring someone to assist you is an excellent option.

It is possible that the fan code error 40 e will occur at an inconvenient time. Always make sure to check the machine on a regular basis for any fan movement or exposed wires that could cause it to malfunction and stop working. Additionally, by spending just a few minutes checking the refrigerator, you can ensure that it will last you much longer than a different model.
