Samsung Dryer Error Codes and What They Mean: Complete 2026 Guide
Your Samsung dryer suddenly stops working, and an unfamiliar error code flashes on the display. Before calling a repair technician and spending hundreds of dollars, understanding these error codes can save you time, money, and frustration. This guide decodes the most common Samsung dryer error codes and provides practical solutions you can try at home.
Understanding Samsung Dryer Error Codes
Samsung dryer error codes are diagnostic messages displayed on your dryer’s control panel when something isn’t functioning properly. These alphanumeric combinations act as your dryer’s communication system, pinpointing specific issues from door malfunctions to temperature problems.
Modern Samsung dryers use these codes to help homeowners troubleshoot issues quickly. Rather than guessing what’s wrong, the error code tells you exactly which component or system needs attention. This smart feature can prevent minor problems from becoming major repairs.
Quick Troubleshooting: The First Step for Any Error Code
Before diving into specific error codes, try this universal reset method that resolves many temporary glitches:
- Unplug your dryer from the power source
- Wait at least 60 seconds
- Plug it back in and restart
This simple power cycle clears the dryer’s internal memory and often eliminates error codes caused by temporary electronic hiccups. If the code reappears, proceed with the specific troubleshooting steps below.
Door and Latch Error Codes
Error Codes: dE, dF, dC, do, d0, 1DC, 1dF
These codes indicate your dryer’s door isn’t closing or latching properly, which prevents the drying cycle from starting.
What Causes This:
- Clothing or lint trapped in the door seal
- Damaged or misaligned door latch
- Worn door strike or gasket
- Sensor malfunction detecting door status
How to Fix:
- Open the door completely and check for any items caught in the seal
- Inspect the door latch for visible damage or debris
- Close the door firmly until you hear a distinct click
- Ensure nothing is blocking the door from closing completely
- Check if the door seal is intact without tears or gaps
If the latch appears broken or the code persists after these checks, the door latch assembly may need replacement. This is typically an affordable part that’s relatively easy to install.
Temperature and Heating Error Codes
Error Codes: tE, tS, t5, tC, tO, t0, tE3, tC5, tCS, 1tC, 1tC5, 1tCS
Temperature-related error codes are among the most common Samsung dryer issues. These indicate problems with the dryer’s heating system or temperature sensors.
What Causes This:
- Clogged lint screen restricting airflow
- Blocked exhaust vent trapping heat
- Faulty temperature sensor
- Low voltage supply on electric dryers
- Buildup from dryer sheets coating sensors
How to Fix:
- Remove and thoroughly clean the lint filter
- Vacuum the lint filter housing area
- Disconnect and clean the entire vent system from dryer to exterior
- Wipe the moisture sensors (usually two metal bars inside the drum) with rubbing alcohol
- For electric dryers, verify proper voltage supply with an electrician
- Check that the outdoor vent flap opens freely
Regular maintenance prevents these errors. Clean your lint trap after every load and deep-clean your dryer vent system at least once yearly. A clogged vent doesn’t just trigger error codes it’s also a serious fire hazard.
Overheating Error Codes
Error Codes: HC, hE, HC4, 1HC
These codes mean your dryer is running too hot, which triggers an automatic safety shutdown.
What Causes This:
- Severely restricted airflow from lint buildup
- Malfunctioning thermostat
- Incorrect voltage on electric models
- Defective heating element stuck in the "on" position
How to Fix:
- Immediately stop using the dryer and let it cool completely
- Clean the lint filter and entire vent system thoroughly
- For electric dryers, have an electrician verify the voltage matches specifications (typically 240V in the US)
- Ensure the dryer has proper ventilation space around it
- Check that the outdoor vent isn't blocked by debris, bird nests, or snow
Never ignore overheating codes. Continued operation with an overheating dryer poses serious fire risks and can damage your clothes and the appliance itself.
Ventilation Error Codes
Error Codes: Clg, Cg, C80, C8, C90, C9
These codes appear after running a vent blockage test and indicate airflow restriction levels.
What Causes This:
- Clg/Cg: Vent is clogged
- C80/C8: Approximately 80% blockage
- C90/C9: Over 90% blockage
How to Fix:
- Disconnect the dryer from power
- Remove the vent hose from the back of the dryer
- Use a dryer vent cleaning brush to remove lint buildup
- Check the exterior vent opening for obstructions
- Consider professional vent cleaning for long or complex vent runs
A partially blocked vent reduces efficiency, increases drying time, and raises your energy bills. Severe blockage creates dangerous conditions that can lead to dryer fires.
Control Panel and Button Error Codes
Control Panel and Button Error Codes
These codes signal that one or more control panel buttons are stuck or continuously registering as pressed.
What Causes This:
- Sticky residue from laundry products
- Debris trapped around buttons
- Damaged or worn button mechanisms
- Moisture affecting button contacts
How to Fix:
- Turn off the dryer completely
- Press each control panel button individually, working from edge to edge
- Use a slightly damp cloth to clean around all buttons
- Ensure no soap, fabric softener, or other residue has built up
- Allow the panel to dry completely before restarting
If buttons appear physically damaged or the code returns immediately, the control panel may need professional replacement.
Communication Error Codes
Error Codes: AC, Et, AE, E3, EEE, AE3, AE4, AE5, 1AC
These indicate that internal dryer components aren’t communicating properly with each other.
What Causes This:
- Loose wire connections
- Control board malfunction
- Sensor failure
- Temporary electronic glitch
How to Fix:
- Unplug the dryer for at least one minute
- Plug it back in and restart the cycle
- If the error returns, check that the dryer is properly grounded
- Inspect visible wire connections for looseness
Communication errors that persist after a reset typically require professional diagnosis. The control board, wiring harness, or multiple sensors may need attention.
Power Frequency Error Codes
Error Codes: FE, 1FC, FC
These codes indicate an invalid power source frequency affecting dryer operation.
How to Fix:
- Restart the drying cycle
- If the error continues, verify your home's electrical frequency matches the dryer's requirements
- Contact Samsung support or a technician for persistent issues
This error is relatively rare and often indicates electrical compatibility issues.
Firmware Update Code
Error Code: dn
This code appears when your dryer is downloading and installing a software update.
What to Do:
- Do NOT unplug the dryer while this code displays
- Allow the update to complete (can take several hours)
- The dryer will restart automatically when finished
- If the code persists beyond 24 hours, contact Samsung support
Interrupting a firmware update can render your dryer inoperable and require service to restore functionality.
Preventing Future Error Codes
Regular maintenance keeps your Samsung dryer running smoothly and reduces error codes:
After Every Load:
