Samsung dryer error codes: tE = thermistor (temperature sensor) fault. dE = door not closed or door switch failed. HE = heater fault (element or relay). bE = button/key stuck on control panel. d80/d90/d95 = vent restriction percentage. clE = child lock active (hold Child Lock 3 sec). FE = power supply frequency error (rare, electrical issue). Samsung dryers use the same tE/dE/HE format across all models.
When these codes pop up on your Samsung display, they're usually trying to save your heating element or your house from a fire. I see d80 through d95 more than anything else in the field, and those are unique because they actually measure exhaust backpressure. Ignore a tE or HE code long enough and you'll blow the thermal fuse, which turns a simple sensor swap into a full teardown. Don't wait on these.
Samsung dryers are incredibly sensitive to airflow and electrical resistance. A dE code is usually just a loose door latch, but codes like bE or FE often point to a control board that's getting noisy power. Most of these can be diagnosed with a basic multimeter before you start ordering parts. Honestly, I've fixed 80% of these Samsung calls in under an hour with just a screwdriver and a meter.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
The dryer runs a full cycle but clothes come out just as damp as they went in, because the heating circuit isn't firing at all.
Display flashes a code and the drum stops mid-cycle, usually within the first 10-15 minutes of a heated run.
Door won't start a cycle even though it clicks shut, and dE appears on the display the moment you press Start.
You put your hand in front of the exterior vent cap and can barely feel any airflow, and the display is showing d80 or higher.
One button on the control panel seems to activate on its own, or you press it and absolutely nothing happens no matter how many times you try.
Can you reset a Samsung dryer to clear the HUB-CODES code?
Unplug the dryer or flip the 240V breaker and leave it off for at least 60 seconds. That gives the control board capacitors time to fully drain. Flip it back on or plug it in, then press Power. If a clE child lock code is showing, hold the Child Lock button for 3 full seconds until it clears. The display should come back clean with no codes showing.
Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Frequently Asked Questions
How much does it cost to fix a Samsung dryer error code?
Depends a lot on which code you've got. A thermistor for a tE code is usually $15 to $30 for the part and maybe an hour of your time. A heating element assembly for an HE code runs $40 to $90 depending on the model. If you're calling a pro, expect $250 to $450 total, which covers the service call, labor, and their markup on parts. The d80 through d95 vent codes cost you nothing if you can clear the blockage yourself. Control board replacements for bE or FE codes hurt the most, usually $150 to $300 for the board alone.
Can I fix these Samsung error codes myself?
Honestly, yeah, most of them. Samsung dryers are pretty modular and the top panel comes off with just two screws. Thermistor swaps, door switch replacements, and vent cleaning are all totally DIY-friendly if you're comfortable with basic tools. The heating element takes maybe 30 more minutes because you're pulling the back panel off. Where I'd call a pro is if you're seeing FE codes in a house with older wiring, or if the control board needs replacing and you haven't done that before. The wiring connectors on that board are fragile and easy to snap if you're rushing.
Is it worth fixing a Samsung dryer or should I just buy a new one?
If it's under 10 years old, fix it. Seriously. Samsung's dryer drums and motors last forever. It's the sensors and door switches that fail, and those are cheap parts. I only start recommending replacement when the repair cost is going to hit 60% or more of a new unit's price, or if the drum itself is cracked or the bearings are completely shot. A $60 thermistor repair on a 5-year-old Samsung is a no-brainer. Now if you're looking at a 12-year-old machine that needs a new control board AND a heating element AND a belt, maybe have that conversation.
Why does my Samsung dryer keep showing d90 or d95 even after I cleaned the vent?
This one gets me called back a lot. Cleaning the lint trap isn't the same as cleaning the vent. The code's measuring total airflow resistance through the whole exhaust path. Check three things: is your duct run longer than 25 feet total? That alone can cause chronic d90 codes. Second, count the 90-degree elbows in the run, because each one counts as roughly 5 extra feet of restriction. Third, pull the dryer out and vacuum inside the blower housing at the back of the drum. Lint packs up in there and it won't show up when you just look at the duct from outside.
What happens if I ignore a tE or HE code and keep running the dryer?
Don't do it. When the thermistor fails, the control board loses its ability to regulate temperature, so the heater can run full blast with no shutoff. That blows the thermal cutoff fuse, which is a one-time safety device. Now instead of a $20 thermistor repair, you're also replacing the thermal fuse and running continuity checks on the high-limit thermostat too. It turns a 30-minute job into a 2-hour job. And in a worst case, you're looking at a real fire risk if enough heat builds up with no airflow. Just stop running it until it's fixed.
