Samsung DVE45T3400V/A3-00 dryer Parts

To reset your Samsung dryer model DVE45T3400V, we recommend a simple power reset: turn the dryer off, unplug it (or switch the breaker off) for about 1 minute, then restore power and start a cycle again. This clears many temporary control glitches.

Quick reset steps (recommended)

• Press POWER to turn the dryer off.
• Unplug the dryer from the outlet (or turn the circuit breaker off).
• Wait 60 seconds.
• Plug the dryer back in (or turn the breaker on).
• Press POWER, select a cycle, then press START/PAUSE.
• If an information code returns, note the code before trying anything else.

For control-panel and operating details specific to this model, use the DVE45T3400V user manual.

If the dryer is showing an information code

A reset may clear a one-time glitch, but repeated codes usually point to a venting, door, temperature-sensing, or power-supply issue.

• If the code comes back immediately after a reset, troubleshoot the code instead of repeatedly power-cycling.
• If drying performance is poor, run the built-in Vent Blockage Test (this model supports it).
• If you see Smart Care related messages, confirm the dryer is not waiting for remote commands.

For code definitions and next steps, use our Samsung dryer error codes resource.

What a reset does (and does not do)

What you are trying to fix	Will a power reset help?	What to do next if it doesn’t
Frozen display, buttons not responding	Often	Check power supply, then consider control troubleshooting
Dryer won’t start a cycle	Sometimes	Check door closure, start/pause operation, and power
Long dry times or “vent clogged” style codes	Rarely	Clean lint screen and inspect/clean venting
Repeating temperature or sensor codes	Unlikely	Troubleshoot the specific code and related components

Why it matters

Resetting is a fast first step that can clear temporary electronic “hang-ups,” but it will not correct airflow restrictions, wiring/power problems, or failed parts like a door switch, thermistor, or control board.

On the Samsung DVE45T3400V dryer, “E3” is not an information code we can confirm from the model’s documented code list in the DVE45T3400V user manual. In many cases, “E3” is a misread display (for example, “3E”, “tC”, “dC”, “HC”, or a vent check code).

Confirm what the display is actually showing

Before troubleshooting, we recommend verifying the exact characters on the display.

• Power the dryer off, then back on, and watch the code reappear.
• Check if it is actually 3E (not E3) or a letter-number code like tC, dC, HC, C80/C90, or Clg/Cg.
• If the code appears during installation checks, it may be a vent blockage test result.
• If the code appears only with a load, reduce the load size and retry.
• If the code appears immediately with an empty drum, suspect a sensor, wiring, or control issue.

Codes this model commonly uses (examples)

The DVE45T3400V documentation includes vent check codes and other information codes such as temperature sensor and door-related codes.

What you see	What it generally points to	First action
Clg (Cg), C80, C90	Vent restriction level	Clean lint screen and inspect/clean venting
dC	Door not closed or door switch signal issue	Close door firmly, check latch area
tC	Temperature sensor error	Service diagnosis is typically needed
HC	Abnormal temperature detected	Check power connection and venting

Why it matters

Misreading the code can send you down the wrong repair path. On this Samsung dryer, vent restriction and temperature-related codes are common; correcting airflow issues can prevent overheating, long dry times, and repeat shutdowns.

For Samsung dryers like model DVE45T3400V, the most common service issue we see is no heat or weak heat, which is usually tied to airflow restrictions (lint buildup or a blocked vent) or a failed heating component (heating element on electric models, or ignition components on gas models). See the troubleshooting section in the DVE45T3400V user manual.

Most common causes (in order to check)

• Restricted exhaust venting (kinked duct, crushed flex duct, clogged wall vent hood)
• Lint buildup (lint screen, blower housing, internal ducting)
• Failed heating system part (electric heating element, gas igniter, flame sensor, gas valve coils)
• Safety device opened (thermal fuse or thermal cut-off due to overheating)
• Power supply issue (electric dryers can run but not heat if one leg of 240V is missing)

Quick checks we recommend for DVE45T3400V

1. Clean the lint screen and confirm it is seated correctly.
2. Check airflow at the outside vent hood; it should be strong and steady.
3. Run the built-in vent check (Vent Blockage Test) described in the manual.
4. If the drum tumbles but there is no heat, troubleshoot the heating circuit (electric) or ignition system (gas).

Symptoms and what they usually point to

Symptom	Most likely category	What to check first
Clothes take too long to dry	Airflow restriction	Venting, lint screen, duct length/elbows
Dryer runs but no heat	Heating system or power	Heating element or gas ignition; verify correct voltage
Loud thumping/squealing	Drum support/drive	Rollers, idler pulley, drive belt
Stops mid-cycle	Overheating or control sensing	Venting, thermistor, moisture sensor

Why it matters

No-heat and long-dry complaints are often caused by poor venting, and that can also lead to overheating, nuisance shutdowns, and premature failure of parts like thermal fuses and heating components.
