Samsung Dryer Error Code System#
Samsung uses a consistent coding scheme across all dryer models. Each code consists of letters indicating the system followed by numbers indicating the specific fault. Unlike Whirlpool's F#E# format, Samsung combines both into shorter codes.
Complete Samsung Dryer Error Code Reference#
| Code | System | Meaning | Severity |
|---|---|---|---|
| HE / HE1 | Heater | Heating element failure or overheating | High |
| HE2 | Heater | Heater relay stuck on | Critical — unplug immediately |
| tS / tO | Temperature | Temperature sensor open/short circuit | Medium |
| tE / tE1 / tE2 | Temperature | Thermistor failure | Medium |
| dC | Door | Door switch not confirming closed | Low |
| dE | Door | Door opened during cycle | Low |
| bE / bE2 | Button | Control panel button stuck | Low |
| AE / AE4 | Communication | Board-to-board communication failure | Medium |
| Et | Ventilation | Exhaust temperature too high (vent blocked) | High — fire risk |
| FE | Frequency | Power supply frequency abnormal | Low |
| 9C1 / 9E1 | Voltage | Low voltage detected | Low |
| Clg | Ventilation | Vent clogging indicator (preventive) | Maintenance |
| HC / HC4 | Gas | Gas ignition failure (gas models only) | High |
Entering Samsung Diagnostic Mode#
- Power the dryer on (standby mode).
- Press and hold Dry Level + Time simultaneously for 3 seconds.
- Display shows "d" or "tSt" confirming diagnostic mode.
- The unit cycles through component tests: door switch, thermistor (displays temperature), heater relay (listen for click), motor, and moisture sensor.
- Press Power to exit.
Smart Care alternative: Open SmartThings app, select dryer, tap Support then Smart Care. The app reads diagnostic data via NFC or audio tones.
Safety First — Know the Risks
Gas dryers carry carbon monoxide and explosion risk. Even electric dryers involve 240V circuits that can deliver a fatal shock. Our techs are licensed and insured — let them handle the risk.

Troubleshooting Key Error Codes#
HE / HE1 — Heating Element Failure#
The control board energized the heater relay but does not detect expected temperature rise. Samsung electric dryers (DVE series) use a coiled Nichrome element, part DC47-00019A. Access from rear panel — 4 Phillips screws.
Our repair teams consistently find wear on the primary failure component as the leading trigger for this issue on Samsung appliances.
Testing: Disconnect element leads. Multimeter on resistance — normal: 7-20 ohms. OL = burned through. Also test each terminal to housing (ground) — any reading indicates fire-risk short. Replace immediately.

tS / tE — Temperature Sensor/Thermistor Error#
The thermistor (DC32-00007A) is an NTC resistor on the blower housing. At room temperature: approximately 10,000 ohms. If reading outside expected range, the board cannot regulate temperature.
| Professional Cost:
Et — Exhaust Temperature High#
A fire safety warning — exhaust temperatures exceed approximately 200 degrees F. Samsung's Vent Sensor system (DVE45T6000+) provides preventive "Clg" code before reaching the "Et" shutdown threshold.
Immediate action: Stop using the dryer. Clean the entire exhaust path from dryer to exterior cap. Check for crushed duct, bird nests, or excessive duct length.
dC — Door Communication Error#
The board is not receiving "door closed" signal from switch DC64-01538A. Causes: worn switch contacts, pinched wiring, or board input circuit damage from power surges.
9C1 / 9E1 — Low Voltage#
Power supply dropped below 216V threshold. Check both breaker poles, look for corroded outlet connections or utility voltage issues. Samsung dryers require 240V within 10% tolerance.
AE — Communication Error#
Main board and display board cannot communicate via ribbon cable. Reseat the ZIF connector. Models without VRT Plus vibration reduction are more susceptible to vibration-loosened connections.
Error Code Reset Procedure#
- Unplug for 5 minutes (Samsung capacitors need full discharge time).
- Reconnect power.
- If code returns within first cycle, the fault still exists.
Some codes (HE2, Et) have a lockout feature — the dryer refuses to operate until the specific fault is resolved. This is a safety feature.
The Real Cost of DIY
Average DIY attempt: $150-400 in tools you may use once, plus the risk of further damage. Our diagnostic visit costs $0 — we find the problem and give you an honest quote.

Error Code Priority Guide#
Address multiple codes in this order:
- HE2 (relay stuck) — immediate safety hazard
- Et (vent blocked) — fire risk
- HE/HE1 (heater failure)
- tS/tE (thermistor)
- AE (communication)
- dC (door)
- bE (button stuck)
- 9C1 (voltage — external issue)
FAQ#
Q: How do I clear a Samsung dryer error code?
Unplug for 5 full minutes, then reconnect. Samsung diagnostic memory stores the last 3-5 error events even through power cycles on newer models. Clearing does not fix the underlying problem.
Q: My Samsung dryer shows HE but still heats — should I worry?
Yes. An intermittent HE code with functional heating may indicate a partial element failure or arcing to ground. This is a fire hazard. Have it inspected promptly.
Q: What does Clg mean on my Samsung dryer?
Clg is the preventive vent-clogging indicator. The dryer still operates, but airflow has degraded. Clean your vent duct soon to prevent progression to the Et shutdown code.
Q: Can I run diagnostic mode without the display working?
Partially. Entering diagnostic mode still activates relay clicks and motor tests you can hear. A clicking pattern during the heater test without actual heating confirms element or relay failure even without visual display.

When Should You Call a Professional?#
Contact a certified appliance repair technician if:
- The issue persists after the basic troubleshooting steps above
- You notice electrical burning smell, sparking, or any sign of electrical damage
- The repair involves gas connections or high-voltage components
- Your Samsung dryer is within warranty — professional diagnosis preserves warranty coverage
- You are uncomfortable working with electrical or gas-connected appliances
EasyBear technicians carry Samsung OEM parts and model-specific diagnostic tools on every service call, eliminating return visits for parts ordering.
What Does the Repair Cost Breakdown Look Like?#
Here is what Samsung dryer error code displayed repair cost varies by component:
- Diagnostic fee: Covers inspection, testing, and identifying the root cause
- Parts: depends on which component has failed; OEM parts for Samsung may cost more than aftermarket
- Labor: most repairs take 30-90 minutes on-site
Total estimated range varies by model and repair complexity. EasyBear technicians provide an upfront quote after diagnosis — no hidden fees. The diagnostic fee is waived when you proceed with the repair.
Prevention Tips for Your Samsung Dryer#
Regular maintenance reduces the likelihood of unexpected breakdowns and extends the life of your Samsung dryer:
- Clean the lint filter after every load — lint buildup reduces airflow and creates a fire hazard.
- Have the dryer vent duct professionally cleaned annually to prevent clogs and overheating.
- Inspect the exhaust vent flap outside your home to confirm it opens when the dryer runs.
Following these maintenance steps can help avoid costly repairs and keep your Samsung dryer running efficiently for years.
