Samsung dryers are good at telling you when something is wrong, but the codes can be cryptic. One of the most common ones we see in Calgary homes is HE, which can also show as HC or hE depending on the model and display. The meaning is the same: the dryer is overheating or heating abnormally. It usually appears partway through a cycle, after the drum has been warm for a while, and the dryer then stops heating to protect itself.
The good news is that the most common cause is something you can check yourself in a few minutes. Here is what the code means, the related Samsung codes that often appear with it, the checks to try, and what a technician looks at when it keeps coming back.
What the HE code means
According to Samsung, HE, HC and hE all point to the dryer overheating or heating abnormally. The control watches the temperature inside the dryer through a thermistor. If it climbs too high, or does not behave the way the control expects, the dryer stops the heat and shows the code.
The usual causes are:
- A clogged lint screen that restricts airflow through the drum.
- A blocked or restricted vent between the dryer and the outside.
- Low voltage on electric models, which can make the heater behave abnormally.
If those are all fine, a technician will look at the heating system and temperature sensors.
Related Samsung codes
HE often shows up alongside other codes that point to the same airflow, temperature or power issues. This table lists the ones Samsung publishes that are most likely to appear with it.
| Code | What Samsung says it means | First thing to try |
|---|---|---|
| HE / HC / hE | Overheating or heating abnormally | Clean the lint screen, check the vent |
| tE / tS / tO / tC | Temperature or sensor problem | Clean screen and vent; call if it returns |
| Clg / Cg | Vent blockage test: vent is clogged | Clear the duct and outside hood |
| C80 / C90 | Vent about 80% or over 90% blocked | Book a vent cleaning |
| 9E / 9C1 / 9E1 | Abnormal power supply voltage | Remove extension cords, check breaker |
If you see several of these together, airflow is almost always the first place to look. You can find the full list on our Samsung dryer codes section or our all-brand dryer error code page.
Why airflow causes most HE codes
A dryer is designed to move a set volume of air through the drum and out the vent. The heater or burner is sized for that airflow. When the air slows down, the same heat is concentrated in less air, so the temperature near the heater and at the exhaust climbs quickly. The control sees that rise and flags HE long before anything is in danger.
Lint screen residue
A lint screen can look clean and still block air. Dryer sheets and fabric softener leave a waxy film on the mesh that you cannot see. Hold the screen under a tap: if water pools instead of running through, wash it with warm soapy water and a soft brush.
The duct behind the dryer
Pushing the dryer back against the wall can crush the flexible transition duct, and plastic or foil accordion ducts sag and collect lint. Semi-rigid metal duct holds its shape and is much less likely to cause trouble.
The outside hood
Lint, nests, snow and ice all block the hood. In winter, frost can glue the flap half-shut; our post on winter dryer vents explains how to deal with it safely.
Safe checks before you call
Unplug the dryer, or switch off its breaker, before you touch the lint screen housing, the duct or anything behind the machine.
- Clean the lint screen and wash it if it is coated. Vacuum out the lint screen slot with a narrow nozzle.
- Check the duct behind the dryer. Pull the dryer out gently and make sure the duct is not crushed, kinked or disconnected.
- Check the outside vent. With the dryer plugged back in and running, you should feel strong airflow at the hood. Clear any lint, snow or ice from the flap.
- Check the power on electric models. Make sure the dryer is plugged straight into its own outlet, with no extension cord, and that both sides of the double breaker are on. Resetting a tripped breaker is fine; anything beyond that is a job for an electrician.
- Reset the dryer. Leave it unplugged for a few minutes, then plug it back in and run a timed cycle with a small load.
Never bypass a thermal fuse or temperature limit to clear the code. Those parts are what stop a hot dryer from becoming a fire.
When the code comes back
If HE returns after you have cleaned the lint screen and confirmed good airflow, the cause is usually inside the dryer. A technician will check:
- The thermistor that reads the temperature, and its wiring.
- The heating element and thermostats on electric models.
- The burner assembly and its sensors on gas models.
- Lint build-up inside the cabinet and around the blower wheel.
- Supply voltage at the terminal block.
A long or poorly routed vent can also cause repeat HE codes even when it is clean. Our post on a dryer overheating and our dryer vent cleaning service page explain more. If the dryer has also stopped heating completely after an HE code, a thermal fuse may have blown, which we cover in why a thermal fuse keeps blowing.
Gas Samsung dryers
On gas models, do not open the burner area or touch the gas valve. If you ever smell gas, leave the house right away and call ATCO Gas emergency at 1-800-511-3447 from outside. Burner, igniter and gas valve work belongs with a qualified technician; our gas dryer repair page explains what we service.
How to keep HE from coming back
Once the code is cleared, a few habits keep the airflow strong and the temperature where Samsung intended it.
- Clean the lint screen before every load, not every few loads. Even a thin layer of lint cuts airflow noticeably.
- Wash the screen every couple of months if you use dryer sheets or liquid softener.
- Run the vent check if your model has one. Many Samsung dryers can test the vent and report Clg or a percentage. Running it every few months shows a blockage forming before HE appears.
- Do not overload the drum. Air needs room to move through the clothes. A half-full drum dries faster and cooler than one packed to the top.
- Have the full vent run cleaned regularly. Once a year suits most homes, and more often for long runs, roof vents or busy households.
- Keep the space behind the dryer clear so the duct is never pinched against the wall.
These steps also help the heating parts last longer, because a dryer that breathes freely does not push its element or burner to the limit on every cycle.
