Samsung Dryer HC Error
What it means
The HC error (related codes include hE, HC4, and 1 HC) means the Samsung dryer is getting too hot. The dryer monitors drum temperature with a thermistor, and when it climbs past the safe limit the control board cuts the heat and pauses the cycle to protect the dryer and your clothes. It's almost always caused by restricted airflow — a clogged lint screen or blocked vent — which traps heat inside.
The bottom line on the HC error
HC is an overheating shutdown, and nine times out of ten the real cause is restricted airflow — a clogged lint screen or blocked exhaust vent trapping heat — not a failed part. The trap is restarting into a hot drum, which can blow the non-resettable thermal fuse and turn a free cleaning job into a service call.
Let the drum cool, then clean the lint screen and the full vent run. Most HC errors clear at no cost this way. Only if a thermistor or heating element has failed on an older dryer does paid repair become worth it against replacement.
HC snapshot
This is an overheating shutdown and a fire risk — let the drum cool, do not restart into a hot drum, clean the full vent run, and unplug (or shut off the gas) before any inspection; leave thermal or gas parts to a technician.

Common causes of the HC error
- Clogged lint screen or secondary lint trap
- Blocked, kinked, or crushed exhaust vent or duct
- Lint buildup in the wall duct or exterior vent flap
- Low voltage to an electric dryer (heater can't regulate properly)
- Failed thermistor or cycling thermostat (less common)
Which Samsung dryers get the HC error
HC (and its variants hE, HC4, and 1 HC) appears across Samsung's DVE/DVG electric and gas dryer lines from roughly 2015 onward, including many front-load models paired with the matching washers. It's most often reported on units installed with long or lint-clogged vent runs rather than being tied to one specific series.
How to fix the Samsung Dryer HC error
- 1Stop the cycle and let it coolOpen the door and let the drum cool for 15–20 minutes before running again. Restarting straight into a hot drum can trip the thermal fuse — a non-resettable safety part that requires service to replace.
- 2Unplug the dryer for safetyBefore cleaning the vent or moving the dryer, unplug it from power (for gas models, this also lets things cool safely).
- 3Clean the lint screen thoroughlyRemove and clear the lint filter completely. On Samsung models with a secondary lint trap under the door lip, clean that compartment too — built-up lint is the most common airflow restriction.
- 4Clear the exhaust vent and ductPull the dryer away from the wall and inspect the flexible duct for kinks, crushing, or disconnected sections. Clean lint out of the duct and check that the exterior vent flap opens freely and isn't blocked.
- 5Reset and run a test cyclePlug the dryer back in and run a short cycle. If HC stays cleared, the restriction was in the lint/vent path. If it returns within about 20 minutes, the blockage is deeper in the wall duct or a thermal part has failed.
🧰 When to call a professional
If the lint screen and full vent run are clean but HC returns quickly, the thermistor, cycling thermostat, or heating element may need testing and replacement. On electric dryers, an electrician should verify the supply voltage. These involve electrical/gas components — call a qualified technician.
Samsung HC vs Samsung dC vs LG D80 (D90/D95): how they compare
How this code stacks up against related error codes for difficulty, urgency, and cost.
| Samsung HC | Samsung dC | LG D80 (D90/D95) | |
|---|---|---|---|
| DIY difficulty (1–5) | 3 | 2 | 3 |
| Urgency (1–5) | 5 | 2 | 4 |
| Typical cost | $$ | $ | $ |
How much does it cost to fix the HC error?
| DIY parts | Free–$80 |
| Professional repair (parts + labor) | $90–$250 |
| New dryer replacement | $450–$2,200 |
Repair or replace?
The vast majority of HC errors are a free fix — a clean lint screen and clear vent run restore airflow with no parts at all. If a thermistor or thermal fuse needs replacing, parts are cheap ($15–$40) and a pro repair runs $90–$250, which is well worth it on most dryers. Only lean toward a new machine if the heating element assembly has failed (over $200 in parts) on a dryer already 8+ years old, where the repair approaches half the cost of replacing it.
Common replacement parts for the HC error
| Thermistor (temperature sensor) | $15–$40 | Cheap; common culprit when vent is already clean | |
| Thermal fuse / cycling thermostat | $10–$35 | Safety part; may blow after repeated overheating | |
| Heating element assembly | $60–$220 | Less common; higher-cost repair on electric models |
Prices are typical retail ranges and vary by model and supplier — always confirm the exact part number for your appliance before buying. We are not linking parts for this code on purpose: it is a job for a qualified technician, and the right fix here starts with a diagnosis, not a purchase.
Samsung HC error — FAQ
＋ − What does HC mean on a Samsung dryer?
It's an overheating code — the drum temperature exceeded the safe limit, so the dryer cut the heat to protect itself. It's usually caused by restricted airflow from a clogged lint screen or vent.
＋ − Is the Samsung HC error dangerous?
It's a safety shutdown working as intended, but the underlying cause (a blocked vent trapping heat) is a fire risk if ignored. Clean the lint screen and full vent path before using the dryer again.
＋ − Why does HC keep coming back after I clean the lint filter?
If it returns within about 20 minutes, the restriction is likely deeper in the wall duct, or a thermistor/thermostat has failed. Inspect the full vent run, and if it's clear, have a technician test the thermal parts.
