A Samsung dryer that runs but doesn’t heat is one of the most common appliance complaints we hear from San Diego homeowners. The drum spins, the motor hums, but your clothes come out just as damp as when they went in. Samsung dryers have some specific design quirks that make heating failures more common than with other brands, and the fix is often different from what you’d do on a Whirlpool or Maytag.

911 Appliance Repair has been fixing Samsung dryers in San Diego since 1991. This guide walks through the most common reasons a Samsung dryer stops heating, how to identify each one, and when to call a professional.
TL;DR: The most common cause of a Samsung dryer not heating is a broken heating element, followed by a blown thermal fuse and a faulty high-limit thermostat. Samsung dryers are especially prone to lint buildup in the heating element housing, which causes the element to overheat and break. Most repairs cost $150 to $300. If your Samsung dryer isn’t heating, call 911 Appliance Repair at 800-929-1192 for same-day service in San Diego.
Why Samsung Dryers Stop Heating
Samsung dryers use a front-mounted heating element that is particularly susceptible to lint accumulation. Unlike some brands where the heating element is better shielded from lint, Samsung’s design allows lint to collect around the element housing over time. This restricts airflow, causes the element to overheat, and eventually breaks the heating coil or blows the thermal fuse.
Samsung dryers also use electronic control boards that manage the heating cycle. A failure in the control board, the thermistor (temperature sensor), or the wiring between them can prevent the heating element from receiving power even when the rest of the dryer works fine.
Common Causes of a Samsung Dryer Not Heating
1. Broken Heating Element
The heating element is the most common failure point on a Samsung dryer. Samsung uses a wire coil inside a metal housing, and the coil can break or burn through over time. Lint accumulation in the housing accelerates this failure by trapping heat around the coil.
How to check: Unplug the dryer and remove the front lower panel. The heating element is located at the front bottom of the dryer. Remove the element and inspect the coil for visible breaks. Test with a multimeter for continuity. If the coil is broken or shows no continuity, replace the heating element.
Cost to replace: The part typically costs $40 to $90. Total repair cost including labor is usually $150 to $280.
2. Blown Thermal Fuse
The thermal fuse is a safety device that cuts power to the heating element if the dryer overheats. Once it blows, the dryer will run but will not heat. On Samsung dryers, a clogged dryer vent is the most common cause of a blown thermal fuse.
How to check: Unplug the dryer, locate the thermal fuse (on the blower housing near the heating element), and test it with a multimeter for continuity. If there is no continuity, the fuse is blown and must be replaced.
Important: Always check and clean your dryer vent before replacing a thermal fuse. If the vent is clogged, the new fuse will blow again.
3. Faulty High-Limit Thermostat
The high-limit thermostat shuts off the heating element if the dryer gets too hot. If it fails in the open position, the dryer will not heat. This is often caused by the same airflow problem that blows the thermal fuse.
How to check: Test the high-limit thermostat with a multimeter for continuity at room temperature. If it shows no continuity, it has failed and needs replacement.
4. Bad Thermistor
Samsung dryers use a thermistor to measure the temperature inside the drum and send that reading to the control board. If the thermistor fails, the control board may not activate the heating element. Samsung dryers may display error codes tE1, tE2, or tE5 when the thermistor fails.
How to check: Test the thermistor with a multimeter. At room temperature (77 degrees F), a Samsung thermistor should read approximately 10,000 ohms. If the reading is far off or shows no continuity, replace the thermistor.
5. Clogged Dryer Vent
A clogged dryer vent is the most overlooked cause of Samsung dryer heating problems. When lint builds up in the vent, airflow is restricted, the dryer takes longer to dry clothes, and eventually the thermal fuse blows or the high-limit thermostat trips. Even if the vent is only partially clogged, the dryer may not heat properly.
How to check: Disconnect the dryer vent hose from the back of the dryer and check for lint buildup. Check the exterior vent cap outside your home to make sure it opens fully when the dryer runs. If you find significant lint, clean the vent or have it professionally cleaned.
6. Failed Control Board
The electronic control board manages all dryer functions including the heating cycle. If the control board fails, it may not send power to the heating element even though everything else works. This is less common than a heating element or thermal fuse failure but does happen, especially on older Samsung dryers.
How to check: Check for burned or scorched spots on the control board. Test for voltage at the heating element terminals when the dryer is running. If there is no voltage reaching the element but the thermistor and thermostats test fine, the control board is likely the problem.
7. Tripped Circuit Breaker
Electric dryers use 240 volts, which means they use two circuit breakers. If one trips, the dryer will run (the motor uses 120V) but won’t heat (the heating element uses 240V). This is a simple fix that doesn’t require any parts.
How to check: Check your electrical panel for tripped breakers. If one is tripped, reset it. If it trips again, there may be a short circuit in the dryer that needs professional diagnosis.
Samsung Dryer Error Codes for Heating Problems
| Error Code | Meaning | Likely Cause |
|---|---|---|
| tE1 | Thermistor open or short | Faulty thermistor or wiring |
| tE2 | Thermistor short circuit | Faulty thermistor |
| tE5 | Temperature sensor error | Faulty thermistor or control board |
| hE | Heater error | Broken heating element or wiring failure |
| FE | Frequency error (motor) | Control board failure (less common) |
If your Samsung dryer displays any of these error codes, the thermistor or heating element is the most likely culprit. Write down the code before calling for repair so the technician can bring the right parts.
How to Reset a Samsung Dryer
Some Samsung dryer heating issues can be resolved with a simple reset, especially if the problem started after a power outage or voltage fluctuation. To reset your Samsung dryer:
- Unplug the dryer from the power outlet.
- Wait at least 10 minutes for the control board to fully discharge.
- Plug the dryer back in.
- Run a test cycle on high heat with a small load of damp clothes.
If the dryer heats after the reset, the issue was likely a temporary control board glitch. If it still doesn’t heat, there is a hardware failure that needs diagnosis. A reset will not fix a broken heating element, a blown thermal fuse, or a faulty thermistor.
How to Tell if a Samsung Dryer Heating Element Is Bad
The most reliable way to test a Samsung dryer heating element is with a multimeter:
- Unplug the dryer and remove the front lower access panel.
- Disconnect the two wires from the heating element terminals.
- Set your multimeter to the resistance (ohms) setting.
- Touch one probe to each terminal on the heating element.
- A functioning element should read between 10 and 50 ohms. If the reading is infinite (no continuity) or far outside this range, the element is broken.
- Also inspect the coil visually for breaks, scorch marks, or gaps.
If you don’t have a multimeter or aren’t comfortable working with electrical components, a technician can test the element in about 10 minutes during a service call.
Samsung Dryer Not Heating: Gas vs Electric
If you have a Samsung gas dryer, the heating system works differently. Instead of a heating element, gas dryers use an igniter, gas valve solenoids, and a burner. The most common gas dryer heating failures are:
- Failed igniter: The igniter glows to light the gas. If it cracks or burns out, the gas valve won’t open and the dryer won’t heat. Test with a multimeter for continuity.
- Bad gas valve solenoids: If the igniter glows but the burner doesn’t light, one or both solenoids have failed. Replace both as a set.
- Flame sensor: The flame sensor detects whether the burner lit. If it fails, the gas valve closes and the dryer stops heating.

Preventing Future Samsung Dryer Heating Problems
- Clean the lint screen before every load. Samsung dryers are especially prone to lint buildup around the heating element, so this is the single most important preventive step.
- Clean the dryer vent annually. Have the vent professionally cleaned if it runs through walls or is longer than 10 feet.
- Check the exterior vent cap. Make sure it opens fully when the dryer runs and isn’t blocked by debris or animal nests.
- Don’t overload the dryer. Overloading restricts airflow and forces the heating element to work harder, which shortens its lifespan.
- Use the right heat setting. Delicate fabrics should use low heat. High heat on every load shortens the heating element’s lifespan.

Frequently Asked Questions
Why is my Samsung dryer running but not heating?
The most common causes are a broken heating element, a blown thermal fuse, a faulty high-limit thermostat, or a bad thermistor. Samsung dryers are especially prone to lint buildup in the heating element housing, which causes the element to overheat and break. Start by checking the circuit breaker and the dryer vent, then test the heating element and thermal fuse with a multimeter.
How do I reset my Samsung dryer that is not heating?
Unplug the dryer from the power outlet, wait at least 10 minutes for the control board to fully discharge, then plug it back in and run a test cycle on high heat. A reset can fix temporary control board glitches but will not fix a broken heating element, a blown thermal fuse, or a faulty thermistor. If the dryer still doesn’t heat after a reset, there is a hardware failure.
How can I tell if my Samsung dryer heating element is bad?
Test the heating element with a multimeter set to the resistance setting. Disconnect the two wires from the element terminals, then touch one probe to each terminal. A functioning element should read between 10 and 50 ohms. If the reading is infinite or far outside this range, the element is broken. Also inspect the coil visually for breaks or scorch marks.
How much does it cost to fix a Samsung dryer that isn’t heating?
Most Samsung dryer heating repairs cost between $120 and $300. A thermal fuse replacement is the least expensive at $120 to $200, while a heating element replacement costs $150 to $280. A control board replacement is the most expensive at $250 to $500. At 911 Appliance Repair, our $49.95 house call is free with repair.
Is there a reset button on a Samsung dryer?
Samsung dryers do not have a physical reset button. To reset the dryer, unplug it from the power outlet, wait 10 minutes, and plug it back in. This resets the electronic control board. If the heating problem is caused by a hardware failure (broken element, blown fuse, bad thermistor), a reset will not fix it.
Can a clogged dryer vent cause my Samsung dryer not to heat?
Yes. A clogged vent restricts airflow, causing the dryer to overheat. This blows the thermal fuse or trips the high-limit thermostat, which shuts off the heating element. Samsung dryers are particularly sensitive to vent clogs because of their heating element design. Always clean the vent before replacing a blown thermal fuse, or the new fuse will blow again.
