Common Symptoms

Error code flashing on the display (HE, HC, FE, Et, bE, etc.)
Dryer stops mid-cycle and won't restart
Dryer runs but clothes are not drying (overheating safety cutout)
Control panel buttons unresponsive
Dryer won't start at all

Most Likely Causes

1
HE / HC — Overheating Error
The HE (Heat Error) or HC (Heat Control) code means the dryer has detected dangerously high temperatures and shut off the heating element as a safety measure. The most common cause is a blocked exhaust vent restricting airflow. This must be fixed before the dryer will run normally.
2
FE — Frequency Error
The FE code means the dryer's control board is detecting abnormal electrical frequency from the power supply. Usually caused by a power surge or an issue with the home's electrical supply. Often resolved with a hard reset.
3
Et — Communication Error
The Et code indicates a communication error between the main control board and the motor control board. Causes include a loose wire harness connection or, less commonly, a failed control board.
4
bE / b2 — Stuck Button Error
The bE or b2 code means one or more control panel buttons is stuck in the pressed position. This can happen from moisture, debris, or a failing button membrane.

Quick DIY Checks

Safety Warning

Unplug the dryer before opening the cabinet or handling internal components. Do not attempt to clean the vent while the dryer is running.

1For HE/HC: disconnect the dryer and thoroughly clean the lint trap, vent hose, and exterior vent cap. Use a dryer vent cleaning brush kit to clear the full duct length. Reconnect and run a test cycle.
2For any code: perform a hard reset. Unplug the dryer for 1–2 minutes, then plug it back in. Many transient errors (FE, Et) clear with a power cycle.
3For FE: check that the dryer is on a dedicated 240V circuit (electric) or 120V (gas). Plug in another 240V appliance or use a multimeter to verify the outlet voltage. If the outlet is fine, the control board may have been damaged by a surge.

4For Et: check the wire harness connections between the main and motor control boards (located inside the dryer cabinet). Unplug the dryer, open the cabinet, and reseat all harness connectors.
5For bE/b2: clean around all control panel buttons with a dry cloth. Press each button firmly several times to free any that might be sticky. If one button is physically stuck down, the control panel overlay may need replacement.

Repair vs Replace

✓ Worth Repairing

Error codes on Samsung dryers are almost always fixable. HE/HC codes that return after vent cleaning may require a new high-limit thermostat or thermal fuse ($10–20). Control board replacement costs $80–150. Replacement only makes sense if the drum bearing or motor has also failed.

Est. Repair Cost

$0–$150 (vent cleaning is free; control board ~$80–150)

Est. Replacement Cost

$600–$1,200 for a new Samsung dryer
