A dryer heating code means the control saw a heat problem: no heat, too much heat or a temperature sensor out of range. Poor airflow causes many of them.

A dryer heating error code means the control saw no heat, too much heat or a temperature sensor reading out of range, and restricted airflow causes many of them.
Dryers measure exhaust temperature with a thermistor. When the reading is missing, too high or never rises, the control shows a code such as Samsung HE or HC, LG tE1 to tE3, or Whirlpool F3 E1 and F3 E2.
LG PS is a different case: it means an electric dryer is getting power on only one leg of its 240-volt supply, often from a half-tripped breaker or a cord wired for another home’s outlet.
Slow drying with a vent warning instead of a heat code is an airflow problem, explained under dryer vent blockage codes. A failed element, fuse or sensor is work for dryer heating element repair in NC.
Samsung HE, LG tE1 and Whirlpool F3 E1 are the heating codes people search most; sensor codes are marked stop because a technician needs to test the part.
| Brand | Code | Meaning | What to do |
|---|---|---|---|
| Samsung | HE / hE / HC | Heating fault; not heating or overheating | Check it yourself first |
| Samsung | tS / tO | Temperature sensor fault | Stop and call |
| LG | tE1 / tE2 / tE3 | Thermistor or temperature sensor fault | Stop and call |
| LG | PS | Power supply fault on an electric dryer | Check it yourself first |
| Whirlpool / Maytag | F3 E1 | Exhaust thermistor open or shorted | Stop and call |
| Whirlpool / Maytag | F3 E2 | Inlet thermistor fault on some models | Stop and call |
Codes are listed for identification. Meanings vary by model, so confirm the code in your owner’s manual.
Heating codes point to the parts that make and measure heat. On electric dryers that means the element, thermal fuse and thermistor; on gas dryers it adds the igniter and gas valve coils.
Samsung HE, shown as hE or HC on some models, means the dryer saw a heating fault. On electric models a blown thermal fuse or open element is common; on gas models the igniter and gas valve coils are the usual suspects.
A restricted vent is often what blew the fuse in the first place, so clear the vent before any heat repair.
LG tE codes point to temperature sensors: tE1 for the main thermistor and tE2 or tE3 for others, depending on the model. A thermistor reads about 10,000 ohms at room temperature on many dryers, which a technician can test.
LG PS means a 240-volt electric dryer is missing power on one leg. Reset the double breaker fully; if PS stays, the outlet or cord needs checking.
F3 E1 means the exhaust thermistor reads open or shorted, and F3 E2 points to the inlet thermistor on models that have one. Loose connectors behind the rear panel are common after a dryer is moved.
Clear the lint path and reset the dryer breaker before booking a heating repair, since both fix a large share of these codes.
A heating code needs a technician when the vent is clear and the code still returns. Switch the dryer off and call when:
Error Code FAQs
Heating code questions usually come from a dryer that tumbles but stays cold, which points to the fuse, element, igniter or a sensor.
HE, or HC on some models, means a heating fault. Clean the lint screen and vent, then reset the breaker. If it returns, the element, gas valve or a sensor may need service.
PS means the electric dryer is not getting full power. Switch the dryer breaker fully off and on. If it persists, have the outlet and cord checked.
Yes. Restricted airflow raises the exhaust temperature and can trip a sensor code. Clear the vent before booking a heating repair.
tE1 points to the main temperature sensor, called a thermistor. Unplug the dryer for a minute; if the code returns, the sensor or its wiring needs service.
F3 E1 means the exhaust thermistor reads out of range. A loose connector or a failed thermistor is the usual cause.
Say whether the dryer is gas or electric and which code it shows.
