The Samsung refrigerator error code 40 e indicates that the refrigerator is not able to maintain the set temperature in the fridge compartment. This is usually caused by a problem with the evaporator fan or the condenser fan.
1. Check the door seal and make sure it is clean and free of debris
- Remove the front panel of the refrigerator.
- Clean the door seal with a cloth and a mild cleaner.
- If the seal is not clean, replace the door seal.
2. Inspect the door gasket and make sure it is intact and properly sealed
To inspect the door gasket on a Samsung refrigerator, you will need to remove the door panel. To do this, remove the screws that hold the panel in place and then pull it off. Once the panel is off, you will see the door gasket. Make sure that the gasket is intact and properly sealed in place. If it is not, you will need to replace the gasket.
3. Check the evaporator fan motor and make sure it is functioning properly
- Open the refrigerator and identify the evaporator fan motor. It is typically located on the back of the unit.
- Inspect the fan for damage or malfunctioning. If the fan is damaged or malfunctioning, replace the motor.
- Check the wiring connections to the fan motor and make sure they are secure. If they are not secure, replace the wiring.
- Test the fan motor by turning it on and off. If the fan motor is not working, replace it.
4. Inspect the condenser coils and make sure they are clean and free of debris
- Remove the front or top cover of the refrigerator. If the cover is attached to the refrigerator with screws, remove the screws and remove the cover. If the cover is attached with pressure-sensitive adhesive, remove the adhesive with a razor blade and a solvent such as acetone.
- Locate the condenser coils. They are usually on the left side of the refrigerator behind the back wall.
- Inspect the condenser coils for debris, ice build-up, and corrosion. Clean any debris or ice build-up with a vacuum cleaner, brush, or cloth. If the coils are corroded, replace them.
- Reattach the cover or replace the screws if it was removed in Step 1.
If you didn't find success with an option above, then try:
- Check the compressor for proper operation.
- Check the thermostat and make sure it is set properly.
- Check for any leaks in the refrigerant system.
- Have a qualified technician inspect and repair the refrigerator.
