Samsung Dryer Error Codes: Complete List with Fixes

Samsung dryers — including the DVE45 and DVE50 electric series, the DVG45 gas models, and the AI-powered Bespoke dryers — use a network of sensors to monitor temperature, airflow, moisture, and motor performance. When something falls outside normal parameters, an error code appears on the display. This guide covers every Samsung dryer error code, whether you have an electric or gas model, and walks you through diagnosis and repair.

How Samsung Dryer Error Codes Work

Samsung dryers monitor exhaust temperature, inlet temperature, drum rotation, moisture levels, and power supply in real time. Error codes appear on the seven-segment LED display or the digital control panel. Some codes stop the dryer immediately (safety codes like HC for overheating), while others allow the cycle to finish before displaying.

Important: Samsung's seven-segment display can make certain letters ambiguous — "tS" and "t5" look nearly identical, and both refer to the thermistor error. "dE" and "dC" both relate to door issues. When in doubt, photograph the display.

To reset most Samsung dryer error codes:

1. Press Power to turn off the dryer.
2. Unplug from the wall outlet for 2 minutes (or turn off the breaker).
3. Plug back in and run a short timed cycle to test.
4. For electric dryers: ensure both legs of the 240V breaker are on — a half-tripped breaker is the #1 cause of phantom errors.

dC / dE / do / d0 — Door Error

The dryer does not detect that the door is closed and latched.

Common causes:

• Clothing caught in the door seal area
• Broken door catch or latch mechanism (Samsung DC66-00326A)
• Door switch failure (Samsung DC64-00828B) — the most common cause on heavily used units
• Weak latch spring on older models (1DC sub-code)

How to fix:

1. Open the door, check for clothing caught in the seal, then close firmly until you hear a click.
2. Inspect the door catch (metal hook on the door) and the latch receiver on the frame for damage or bending.
3. Test the door switch: unplug the dryer, remove the top panel (2 screws at rear), locate the switch near the door frame, disconnect wires, and test for continuity when pressed. No continuity = replace.
4. Samsung dryer door switches cost $8–$15 and take 10 minutes to replace. Always swap the switch before investigating the control board.

Part cost: Door switch (DC64-00828B) $8–$15. Door catch (DC66-00326A) $10–$20. Professional repair $75–$200.

tS / t5 / tC / tO / tE / tE3 — Temperature Sensor Error

The exhaust or inlet thermistor is reading abnormally or has failed. The "tS" and "t5" codes appear identical on the seven-segment display — they are the same error.

Common causes:

• Exhaust thermistor failure (Samsung DC32-00007A)
• Inlet thermistor failure (Samsung DC32-00008A)
• Wiring damage from heat or vibration along the inside panels
• tO variant specifically indicates the outlet (exhaust) thermistor

How to fix:

1. Unplug and access the thermistor — on Samsung dryers, the exhaust thermistor is mounted on the blower housing or exhaust duct.
2. Disconnect leads and test with a multimeter: at 77 degrees F should read approximately 10 k-ohm. At 150 degrees F approximately 3–4 k-ohm. Open or shorted readings mean replacement.
3. Check wiring from the thermistor to the control board — Samsung dryer wiring runs along inside panels where heat and vibration cause damage.
4. Some models have both inlet and exhaust sensors. Identify which the code references using your model's service manual.

Part cost: Exhaust thermistor (DC32-00007A) $10–$25. Inlet thermistor (DC32-00008A) $10–$25. Professional repair $125–$275.

HC / hE / HC4 / 1HC — Dryer Overheating

The dryer has detected exhaust temperature above the safe threshold. This is a fire safety code — take it seriously.

Common causes:

• Clogged lint screen (invisible film from dryer sheets blocks airflow)
• Blocked vent duct from dryer to exterior wall (lint, bird nests, crushed termination)
• Heating element with grounded coil arcing to housing (Samsung DC47-00019A)
• Failed cycling thermostat allowing element to stay on too long (Samsung DC47-00016A)
• HC4 specifically means 4 consecutive overtemp events — almost always restricted airflow

How to fix:

1. Clean the lint screen thoroughly — wash with soap and water to remove dryer sheet film.
2. Disconnect the vent hose and clean the entire duct run with a vent brush or leaf blower.
3. Check the exterior vent flap — it must open freely when the dryer runs.
4. If the vent is clear but HC persists, test the heating element: with a multimeter, check from each terminal to the housing. Any continuity to ground means the element is arcing.
5. Inspect the cycling thermostat (DC47-00016A) and high-limit thermostat (DC47-00018A) near the heating element.

Diagnostic tip: A dryer vent cleaning service ($100–$150) resolves 80% of HC4 codes without any parts replacement.

Part cost: Heating element (DC47-00019A) $30–$60. High-limit thermostat (DC47-00018A) $8–$15. Cycling thermostat (DC47-00016A) $8–$15. Thermal fuse (DC96-00887A) $5–$10.

HC2 — Gas Ignition Failure (Gas Dryers Only)

The gas burner failed to ignite. Applies only to Samsung gas dryer models (DVG series).

Common causes:

• Gas supply shutoff valve closed (handle perpendicular to pipe = off)
• Igniter failure — does not glow orange (Samsung DC47-00076A)
• Gas valve solenoid coils weak (Samsung DC32-00008B — includes both coils)
• Flame sensor misaligned or carbon-coated (Samsung DC32-00009B)

How to fix:

1. Confirm gas supply is on — check the shutoff valve behind the dryer and the main meter valve.
2. Remove the lower front panel. Start a cycle and observe: the igniter should glow bright orange within 30 seconds. No glow = failed igniter.
3. If the igniter glows but gas does not flow, test the gas valve solenoid coils — each should read 1.0–1.5 k-ohm. These coils have a characteristic failure: they work when cold but fail after 10–15 minutes of running.
4. If gas flows but does not ignite, clean the flame sensor and verify its position.

Part cost: Flat igniter (DC47-00076A) $15–$30. Gas valve solenoid coil kit (DC32-00008B) $10–$20. Professional repair $175–$350.

9C1 / 9E / 2E — Voltage Supply Error

The dryer is receiving incorrect voltage from the power supply.

Common causes:

• Electric dryers: half-tripped 240V breaker delivering only 120V (drum turns but no heat)
• Loose terminal connection at the dryer power cord block
• Wrong outlet type (NEMA 14-30 required for 240V electric dryers)
• Gas dryers: extension cord causing voltage drop on 120V circuit

How to fix:

1. Electric dryers require 240V (NEMA 14-30 outlet). Measure with a multimeter — below 200V triggers the code.
2. Check the circuit breaker: turn it fully off, then fully on. A half-tripped breaker delivers 120V — the drum turns but the heater cannot work.
3. Tighten all terminal screws on the power cord connection block at the back of the dryer.
4. Gas dryers only need 120V but are sensitive to voltage drop from extension cords — plug directly into a wall outlet.

Part cost: Typically no parts needed. Power cord (DC96-00757A for 4-prong) $15–$25 if damaged.

3C / 3E — Motor Error

The drive motor has failed or cannot turn the drum.

Common causes:

• Broken drum belt wrapped around the motor shaft (Samsung 6602-001655)
• Seized drum roller (Samsung DC97-16782A) or idler pulley (Samsung DC93-00634A)
• Motor winding failure (Samsung DC31-00055G)
• Motor start capacitor failure (if equipped)

How to fix:

1. Unplug and try to spin the drum by hand — it should rotate freely. Resistance means a mechanical binding.
2. Remove the front panel to access the motor, belt, idler pulley, and rollers.
3. Check the belt — a broken belt is the most common cause. If intact, spin each roller by hand. Worn rollers feel rough or wobble.
4. Test motor windings: disconnect leads and measure 1–3 ohms per winding. Open or shorted = motor failure.

Diagnostic tip: Before replacing the motor, always fix any binding first. A seized drum roller puts excess load on the motor, causing thermal overload — but the motor itself may be fine.

Part cost: Drum belt (6602-001655) $5–$10. Roller kit (DC97-16782A) $15–$30. Idler pulley (DC93-00634A) $10–$20. Motor (DC31-00055G) $50–$100. Professional repair $175–$375.

bE / bE2 / bC2 / 6E — Button Stuck Error

The control panel detects a continuously pressed button.

Common causes:

• Physical button stuck from lint or detergent residue
• Humidity causing phantom touches on capacitive panel (common in humid laundry rooms)
• Membrane keypad failure
• Electrical noise on the control board

How to fix:

1. Unplug and press every button individually. Feel for any that do not spring back.
2. Clean the panel with a slightly damp cloth — never spray liquid directly on it.
3. Unplug for 15 minutes to fully discharge capacitors.
4. If the code only appears in the morning and clears later, humidity is the culprit — aim a small fan at the control panel area.

Part cost: Control panel/touchpad assembly $50–$100 (model-specific). Main control board (DC92-01606A) $80–$150.

AE / EEE / AE4 / AE3 / Et / 1AC — Communication Error

The main control board and display/sub board cannot communicate.

Common causes:

• Power surge or transient disrupting board-to-board communication
• Ribbon cable loose or corroded between boards
• Main control board failure — Samsung dryer boards sit near the exhaust duct and can overheat if the vent is restricted
• EEE specifically indicates EEPROM (firmware memory) corruption — non-recoverable, board must be replaced

How to fix:

1. Unplug for 5 minutes and restore power — communication faults from power transients may clear.
2. Remove the top panel and reseat all ribbon cable and wire harness connections.
3. Inspect for heat damage or corrosion on the main board — boards near restricted vents overheat.
4. If "EEE" appears on the display, the EEPROM is corrupted. No amount of reseating or power cycling will fix it — replace the main board.

Part cost: Main control board (DC92-01606A) $80–$150. Display/UI board (DC92-01310A) $50–$100. Professional repair $200–$400.

FE / FC / 1FC — Power Frequency Error

The power supply frequency is outside the 60 Hz standard range.

Common causes:

• Dryer connected to a generator or unstable power source
• Automatic transfer switch (ATS) for backup generator causing brief frequency instability
• Main control board frequency detection circuit fault (rare)

How to fix:

1. Plug the dryer into a standard wall outlet on utility power (not a generator).
2. If on utility power, use a frequency meter to verify 59.5–60.5 Hz.
3. Check for a faulty ATS if the home has a backup generator — some ATS units cause frequency instability during switching.

Part cost: Main control board (DC92-01606A) $80–$150 if frequency detection is faulty.

oD — Overdrying

The moisture sensor detects that clothes are overdried, typically due to a dirty sensor or restricted vent.

Common causes:

• Dryer sheet residue on moisture sensor bars (invisible waxy film)
• Moisture sensor bar corrosion or damage (Samsung DC97-18700A)
• Partially restricted vent causing extended run times

How to fix:

1. Locate the moisture sensor bars inside the drum — two thin metal strips near the lint filter opening. Clean with rubbing alcohol and a soft cloth.
2. Run a damp towel cycle to calibrate.
3. Check the dryer vent for partial restriction — reduced airflow extends drying times.
4. Clean sensor bars with rubbing alcohol monthly to prevent buildup.

Part cost: Moisture sensor bar assembly (DC97-18700A) $15–$30. Typically resolved with cleaning alone.

Et — Lint Filter Clogged Indicator

The dryer detects restricted airflow through the lint filter area.

Common causes:

• Lint buildup on filter screen or below the filter in the duct
• Torn or damaged filter mesh (lint passes through instead of being caught)
• Vent system restriction causing backpressure

How to fix:

1. Remove the lint filter and clean thoroughly. Wash with warm water and a brush if lint is embedded.
2. Use a flashlight to check down into the filter housing — vacuum out any lint below the filter.
3. Check the entire vent system from dryer to exterior.

Part cost: Lint filter screen $10–$25 (model-specific) if mesh is torn. Otherwise free — just clean it.

Samsung Dryer Diagnostic Mode

Samsung dryers have built-in diagnostic capabilities:

1. SmartThings App Diagnosis: For Wi-Fi-enabled models, open SmartThings, select your dryer, tap Device Care > Self Check. The app runs sensor tests and reports results.

2. Vent Blockage Test: Many Samsung dryers have a built-in vent blockage test. On some models: with the dryer empty and off, press and hold Adjust Time Up + Dry Level for 3 seconds. The dryer runs the blower for 2 minutes and reports vent condition (0–4 bars).

3. Manual Diagnostic Mode: Power on the dryer. Press and hold Temp + Signal (or Adjust Time Up + Adjust Time Down) for 3 seconds. The dryer cycles through component tests: heater, motor, thermistors, and moisture sensor.

4. Error Code History: In diagnostic mode, some Samsung models display the last 5 error codes in sequence. Cycle through using the Temp button.

Frequently Asked Questions

Q: Why does my Samsung dryer turn but not heat? A: The #1 cause for electric dryers is a half-tripped 240V breaker. The motor runs on 120V but the heating element needs 240V. Turn the breaker fully off and then fully on. For gas dryers, check the gas supply valve and igniter. If the drum spins fine but air is cold, the issue is always in the heating circuit — not the motor.

Q: How often should I clean my Samsung dryer vent? A: At minimum once per year, but every 6 months is better for households running 5+ loads per week. In Sacramento, where many dryer vents run through long attic ducts, lint accumulates faster. A professional vent cleaning costs $100–$150 and prevents the HC overheating code.

Q: What does "EEE" mean on my Samsung dryer? A: "EEE" indicates the EEPROM memory chip on the main control board has been corrupted, usually from a power surge. This is non-recoverable — the board must be replaced. Power cycling and connector reseating will not fix EEPROM corruption.

Q: Can I replace a Samsung dryer belt myself? A: Yes — the drum belt (Samsung 6602-001655) is one of the most common DIY dryer repairs. The belt costs $5–$10. You will need to remove the front panel, release the belt from the motor and idler pulley, thread the new belt around the drum, and route it through the idler and motor pulley in a zigzag pattern.

Q: Is a Samsung gas dryer safe to repair myself? A: Electrical components like the door switch, belt, and drum rollers are safe DIY repairs. However, anything involving the gas valve, igniter, or gas supply line should be done by a professional. Gas leaks are a serious safety hazard.

When to Call a Professional

Some Samsung dryer issues require professional diagnosis:

• HC with clear vents — If the vent system is clean but overheating persists, a grounded heating element is arcing and requires electrical testing.
• HC2 (gas ignition) — Gas dryer repairs involving the valve, igniter, or flame sensor should be handled by a professional due to gas safety concerns.
• 3C with free-spinning drum — If the drum turns by hand but the motor code persists, the motor windings or inverter board need professional testing.
• AE / EEE (communication/EEPROM) — Control board replacement requires correct part matching and sometimes firmware configuration.
• Any burning smell, sparking, or visible arcing — Stop using the dryer immediately and call for service.
• Repeated thermal fuse blowing — The fuse is a symptom, not the cause. A professional needs to find what is causing the overheat condition.
