Error Code 40 E Basics
Samsung refrigerators sometimes show error codes to signal a problem. Error Code 40 E is one of these alerts. It helps users identify issues quickly.
Understanding this error code can save time and prevent damage. It points to a specific fault that needs attention.
What Triggers Code 40 E
Code 40 E usually appears due to a defrost sensor problem. This sensor monitors the freezer temperature. If it fails, the fridge cannot regulate frost buildup.
Other causes include wiring faults or a faulty main control board. These parts work together to keep the fridge cold and frost-free.
Common Symptoms
The fridge may stop cooling properly. Ice can build up inside the freezer compartment. You might notice unusual noises or frequent defrost cycles.
The display panel will show the 40 E error code clearly. Food may spoil faster due to temperature issues.

Quick Troubleshooting Steps
Samsung Refrigerator Error Code 40 E usually signals a water flow issue. Quick troubleshooting can help fix this without waiting for a technician. Follow these simple steps to check common causes and restore your fridge’s normal function fast.
Check Water Supply
Start by verifying your home’s water supply is working properly. Ensure the water valve connected to the fridge is fully open. A low water supply or closed valve often causes the 40 E error code. Check for leaks or blockages in the main water line. Good water pressure is essential for your refrigerator’s dispenser and ice maker.
Inspect Water Hose And Filter
Next, examine the water hose behind your refrigerator. Look for kinks or damage that may restrict water flow. Disconnect and inspect the hose filter for dirt or clogs. Clean or replace the filter if it looks dirty. A blocked hose or filter reduces water flow, triggering the error code 40 E.
Clean Dispenser Drawer
Remove the dispenser drawer and clean it thoroughly. Food debris or mineral buildup can block water flow inside the dispenser. Use warm soapy water and a soft brush to clean the drawer parts. Dry everything before putting it back. A clean dispenser drawer helps maintain smooth water operation and prevents error codes.
Resetting The Refrigerator
Resetting your Samsung refrigerator can often resolve the 40 E error code. This process refreshes the system and clears minor glitches. It is a simple step you can try before calling for help. Resetting helps restore normal function quickly.
There are several ways to reset the refrigerator. Use the buttons on the control panel or power cycle the unit. Some models also allow entering a diagnostic mode for a full reset. Each method has clear steps to follow.
Using Power Cool And Power Freeze Buttons
Press and hold the Power Cool and Power Freeze buttons together. Hold them for about 10 seconds until the display flashes. This signals the reset is in progress. The fridge will restart and clear temporary errors.
This method works on many Samsung models. It is the easiest way to reset without unplugging the fridge. After resetting, check if the 40 E code disappears from the screen.
Plugging And Unplugging Method
Unplug the refrigerator from the power outlet. Leave it unplugged for 5 minutes. This allows the system to fully power down and reset.
After waiting, plug the fridge back in. The unit will reboot and clear some error codes. This method resets the main control board and can fix minor faults.
If the 40 E error still shows, try the button reset or diagnostic mode next.
Entering Diagnostic Mode
Press and hold specific buttons to enter diagnostic mode. Usually, this involves pressing the upper left and middle left buttons together.
Hold until you hear a beep or see a special code on the display. This mode runs tests and resets the system deeply.
Follow the on-screen instructions or refer to your manual for exact steps. Diagnostic mode can clear complex errors like 40 E.

When To Document And Call Support
Knowing when to document and call support for the Samsung Refrigerator Error Code 40 E is crucial. This error often signals a problem with the refrigerator’s water supply or cooling system. Acting quickly helps prevent further damage and costly repairs. Keeping a record of the error and recognizing warning signs can save time during technician visits.
Capturing Error Codes
Always write down or photograph the error code as soon as it appears. This information helps technicians understand the issue faster. Use your phone camera to capture the code clearly. Avoid resetting the refrigerator before documenting the error code. Resetting may erase the code and valuable diagnostic data. A clear record speeds up repairs and avoids guesswork.
Signs You Need A Technician
Persistent error codes that do not clear after resetting need professional help. Strange noises or a lack of cooling are warning signs. Water leaks or ice build-up inside the fridge also require expert attention. If the refrigerator stops working or the error code returns repeatedly, call support. Prompt service prevents small problems from becoming serious faults.
Non-error Codes To Note
When your Samsung refrigerator shows a code, it may not always mean a problem. Some codes are just notifications or settings modes. Recognizing these non-error codes helps avoid confusion and unnecessary repairs. These codes often indicate the fridge is in a special mode or showing system information.
Understanding non-error codes saves time. It also helps you use your fridge correctly. Let’s look at two common types: Cooling Off or Demo Mode codes and Access Point display codes.
Cooling Off/demo Mode Codes
Cooling Off or Demo Mode codes appear when the fridge runs in a display mode. This mode is used in stores to show the fridge without cooling. The screen may show “OF OF” or “O FF.”
In this mode, the fridge does not cool. It only lights the display. This saves energy in the store. If your fridge shows this code at home, it means Demo Mode is on by mistake.
To fix this, turn off Demo Mode. Usually, pressing and holding certain buttons clears it. This helps the fridge return to normal cooling. The fridge then cools your food properly again.
Access Point Display
Sometimes, your fridge shows “AP” on the display. This stands for Access Point. It means the fridge’s Wi-Fi or smart features are active.
The Access Point mode lets your fridge connect to your home network. It allows you to control it with an app. This code is not an error. It only shows that the fridge is ready to connect.
If you do not want to use Wi-Fi, you can disable this mode. Follow your fridge manual to turn off the Access Point display.
Preventive Maintenance Tips
Preventive maintenance helps avoid Samsung refrigerator error code 40 E. It keeps your fridge running smoothly. Simple care steps extend the appliance’s life. Regular checks can stop small issues from growing.
Regular Filter Cleaning
Clean the water filter every six months. A dirty filter blocks water flow and causes errors. Remove the filter and rinse it under cold water. Replace the filter if it looks damaged or clogged. This keeps water clean and flow steady.
Water Pressure Checks
Check water pressure at least twice a year. Low pressure can trigger error code 40 E. Use a pressure gauge to measure flow strength. Adjust the water supply valve if pressure is too low. Ensure hoses are not kinked or blocked. Proper pressure keeps your refrigerator’s water system working well.
