Samsung Dryer Error Codes
HE, tE, dC, FE, 9E2 — What They Mean & How We Fix Them
Samsung electric (DV) and gas (DVG) dryers share most fault codes. The codes we see most are hE (heating fault, often a restricted vent), tE (temperature sensor circuit), dC (won't start with the door closed) and dF (door switch).

Samsung Dryer Error Code Repair — Twin Cities — Quick Answer
What we fix in the Twin Cities
The Twin Cities repair mix
How to enter Samsung dryer diagnostic mode
The button sequence for Samsung's diagnostic mode differs by model and year, so check your owner's manual or Samsung's support site for yours. Many Samsung dryers also support Smart Check: the dryer plays a tone that the SmartThings app reads to decode stored faults. On WashTower stacked units the dryer controls are separate from the washer's.
A heating code usually means check the vent first
On Samsung electric dryers an hE code often traces back to a restricted vent. A clogged vent overheats the dryer, which can blow the thermal fuse and stress the heating element. We replace the failed parts and inspect the vent run; replacing only the element without clearing the vent risks the new part failing again. Add-on dryer-vent cleaning is $185, from the dryer to the outside cap.

FAQ
Dryer repair in the Twin Cities: FAQs
What does tE mean on a Samsung dryer?
tE / tE3 is the temperature sensor circuit: the sensor, its wiring or connector. Lint and restricted airflow can also affect what the sensor reads, so clean the lint screen and check the vent first. If tE returns, the sensor or its wiring is next ($225–$345). Cleaning the moisture-sensor strips helps with over- or under-drying, not with tE.
What does hE mean on a Samsung dryer?
hE is a heating fault. On electric dryers it can be the thermal fuse or heating element, often after a restricted vent overheated the dryer, so we inspect the vent as part of the repair. On gas dryers it can be the igniter or gas valve coils. Repair $325–$485 plus an optional $185 vent cleaning.
What does dC mean on a Samsung dryer?
dC means the door isn't registering as closed when you press Start. Open and firmly re-close the door. If dC persists, the door switch or magnet has failed, or the latch is bent. Repair $225–$345.
How do I enter Samsung dryer diagnostic mode?
The sequence differs by model and year, so check your owner's manual or Samsung's support site. Many Samsung dryers also support Smart Check, where the SmartThings app reads a tone from the dryer to decode stored faults.
Why does my Samsung dryer keep blowing the thermal fuse?
A blown thermal fuse means the dryer got too hot, very often from a restricted vent. Clean the vent from the dryer outlet to the exterior cap when the fuse is replaced, or the new fuse can trip again.
How much does Samsung dryer repair cost?
Most Samsung dryer repairs land $245–$485 all-in. Thermistor $225–$345. Door switch $225–$345. Heater + thermal fuse $345–$485 (add $185 vent cleaning). Gas valve coil $245–$345. Main control board (rare) $385–$525. The $149 trip fee is credited toward the repair when you approve it.
Is a Samsung dryer worth repairing?
Often yes, especially for a common repair on a newer unit. The exception is a control-board failure on an older unit, where the math gets closer to replacement. We give you the quote before any work starts, and you decide.

What do Samsung dryer error codes tell me?
A Samsung dryer code names the circuit that failed a check, such as heating, temperature sensing or the door. It does not name the failed part. Read the characters on the display exactly, then use the table below to decide where to look first and what is safe to try.
Central Minnesota Appliance Repair works on Samsung electric and gas dryers across the Twin Cities. The first question on almost every dryer call is the same: how well is the vent moving air? Many codes that look like part failures start with restricted airflow.
Samsung dryer codes, meaning and first check
These are the codes we are confident about. Samsung displays differ between models, so confirm with your manual if your display looks different.
| Code | What it means | What we check |
|---|---|---|
| HE | Heating fault | Vent and airflow, thermal fuse, high-limit thermostat, element or gas valve coils, sensor |
| tE | Temperature sensor fault | Sensor resistance and wiring, then the control |
| dC | Door open or not detected as closed | Latch, door switch and striker |
For the heating code in depth, see Samsung dryer HE error. Other models show other letters, so call with the model number if yours is not here.
Why does my Samsung dryer show tE when the sensor looks fine?
A tE code means the control is reading a temperature sensor outside its range. The sensor may be fine while a loose connector or a damaged wire is the real issue. A sensor that has failed open or shorted shows the same code, so we measure it rather than guess.
Lint can affect temperature readings too, because a coated sensor or a restricted airflow path changes what the sensor sees. Clean the lint screen, vacuum the housing under it, and inspect the vent. If the code stays after that, a technician should test the sensor and the wiring.
Do not probe wires with the dryer plugged in. A 240-volt dryer circuit can seriously injure you. Unplug the dryer before moving it away from the wall to inspect the vent connection.
How often should I clean a Samsung dryer vent in Minnesota?
At least once a year, and more often with a long run or heavy use. A vent that is clean at the start of fall has the best chance of surviving a Minnesota winter, when cold ducts and ice at the hood make airflow worse.
Pull the dryer out, disconnect the transition duct, and look for lint through the full run to the outside hood. Make sure the hood flap opens freely. Use rigid or smooth metal duct where you can, since ribbed foil traps lint. See our dryer vent guide in the blog for more on materials.
If you find a hard clog or the run is long and hard to reach, a professional vent cleaning is worth the cost. Our technician can clean it as part of a repair, and our $149 trip fee is credited toward the repair when you approve it.
More Samsung dryer code questions
Does a code mean I cannot use the dryer at all?
For heating and temperature codes, stop using it until it is checked. For a door code, try re-seating the door first.
Is my Samsung dryer gas or electric?
Electric models have a heavy 240-volt cord. Gas models have a standard cord and a gas pipe at the back. Your model tag says which.
Can I reset the control?
Unplug it for a minute. A repeated code means a real fault.
Where is the model number?
Inside the door frame or on the back panel.
