Samsung dryer AE/AC indicates communication error—internal components can’t talk to each other. Samsung’s fix: Turn off dryer, wait at least 60 seconds, turn back on. This clears most temporary communication glitches. If error persists after multiple resets, a control board or wiring issue may need professional diagnosis.
| Error Code | AE / AC |
|---|---|
| Meaning | Internal communication error between components |
| Difficulty | Easy to Moderate |
| Time to Fix | 5 minutes (reset) to service call |
| Tools Needed | None for reset |
| DIY Fixable | Yes |
| Official Source | Samsung Support |
The AE error means the dryer’s internal components—typically the main control board and user interface board—cannot communicate properly. This is often a temporary glitch resolved by reset, but persistent errors may indicate hardware failure.
Understanding Communication Error Codes
| Code | Meaning |
|---|---|
| AE | Communication error—general |
| AE3 | Communication error variant |
| AE4 | Communication error variant |
| AE5 | Communication error variant |
| AC | Same as AE |
| Et | Communication/EEPROM error |
| EEE | EEPROM error |
| E3 | Communication error |
All these codes indicate communication problems between internal electronic components.
What Causes Communication Errors
Temporary Causes (Fixable by Reset)
- Power surge or fluctuation—disrupted communication
- Static electricity buildup—interfered with signals
- Software glitch—temporary processing error
- Moisture on components—humidity in laundry room
Persistent Causes (May Need Service)
- Failing control board—components degrading
- Loose wire connection—intermittent contact
- Damaged wire harness—broken conductor
- Corroded connectors—poor electrical contact
- Failed user interface board—display/button board issue
Samsung’s Official Reset Procedure
Samsung specifies a 60-second minimum wait time for communication errors.
Step 1: Turn Off Dryer
Press the Power button to turn off the dryer completely.
Step 2: Wait 60 Seconds
This is Samsung’s specified time—not a general suggestion. The 60-second wait allows:
- Communication buffers to clear
- Capacitors to discharge
- Control board to fully reset
Don’t skip this wait time—shorter resets may not clear the communication error.
Step 3: Turn Dryer Back On
Press Power to turn on and check if error has cleared.
If the error clears but returns within a few days, it’s likely a developing hardware issue. Document when it happens (time of day, during specific cycles) to help technicians diagnose the pattern.
Extended Reset (If 60-Second Reset Fails)
If the standard reset doesn’t clear the error:
- Unplug dryer from wall outlet (or turn off breaker)
- Wait 5 minutes for complete power dissipation
- Plug back in
- Turn on and test
This longer reset allows all components to fully discharge and reinitialize.
Checking Wire Connections
If error persists after resets, loose connections may be the cause.
Safety first: Unplug dryer before any internal inspection.
User Interface Connection
The user interface (control panel) connects to the main board via ribbon cable or wire harness.
- Access the control panel area (usually behind top panel)
- Locate ribbon cable or connector
- Unplug and replug the connection firmly
- Ensure connector is fully seated
- Reassemble and test
Main Board Connections
The main control board has multiple connectors for various components.
- Access main board (usually behind rear panel)
- Visually inspect all connectors
- Look for:
- Loose plugs
- Corroded pins
- Burnt or discolored wires
- Reseat any suspect connectors
- Reassemble and test
Warning: If you see burn marks or damaged wires, stop and call a technician.
When AE Indicates Board Failure
Signs the control board is failing:
- Error returns within hours or days of reset
- Multiple different error codes appearing
- Dryer behaves erratically
- Display shows random characters
- Buttons respond inconsistently
Control board replacement:
- Part varies by model ($100-250+)
- Professional installation recommended
- May include firmware that requires programming
Smart Dryer Considerations
For Wi-Fi-connected Samsung dryers, AE can sometimes relate to network communication:
Reset Network Connection
- Turn off dryer
- Wait 60 seconds
- Turn on dryer
- If error persists, remove and re-add device in SmartThings app
Firmware Updates
Smart dryers may have firmware updates that fix communication bugs:
- Open SmartThings app
- Check for available updates
- Install if available
- Retest dryer
Environmental Factors
Communication errors can be triggered by environmental conditions:
High Humidity
Moisture in laundry room can affect electronics:
- Improve ventilation
- Run exhaust fan during and after drying
- Consider dehumidifier
Temperature Extremes
Very cold laundry rooms (garages in winter) can cause condensation on electronics:
- Let dryer warm up before use
- Ensure adequate heating in space
Power Quality
Poor power quality causes communication issues:
- Use dedicated circuit for dryer
- Consider surge protector (whole-house type)
- Contact electrician if power problems suspected
When to Call a Professional
Contact Samsung service (1-800-726-7864) or a technician if:
- Error returns within 24 hours of reset
- Multiple error codes appearing
- Visible damage to wiring or boards
- Dryer under warranty
- You’re not comfortable with internal inspection
What to Tell the Technician
Helpful information to provide:
- Exact error code (AE, AE3, AC, etc.)
- When error first appeared
- How often it occurs
- What you were doing when it happened
- Whether reset cleared it temporarily
- Any other symptoms or codes
