You throw a load of wet towels into your Samsung dryer, set the cycle for 60 minutes, and return to find the cycle aborted, the drum cold, and error code HE (or hE) flashing on the digital LED display. On some models, the error code displays as tE.
Both HE and tE are heating circuit diagnostics:
- HE / hE stands for Heating Error: The electronic control board detected that the internal drum air temperature failed to rise after the motor started.
- tE stands for Thermistor Error: The temperature sensor resistor reading is shorted, open, or out of its expected resistance range.
In over 85% of Samsung electric dryers, the problem is caused by a burned-out heating element coil or a tripped thermal safety fuse on the heater housing.
QUICK SUMMARY: THE 30-MINUTE FIX
On Samsung dryers, the heating element, thermal fuse, and high-limit thermostat are all housed together in a metal heater duct located behind the front-bottom-right kickplate. Testing these components with a $10 digital multimeter isolates the burned component in under 10 minutes.
SAFETY WARNING
DANGER: Electric dryers utilize high-voltage 240V AC power. You must unplug the heavy power cable from the wall outlet or trip the double-pole circuit breaker before touching any electrical terminals.
THE 3 CAUSES OF SAMSUNG DRYER HEATING FAILURES
- Broken Nichrome Heating Element Coil (Most Common)
Electric dryers use a coiled wire made of nickel-chromium alloy that glows red-hot when 240V is applied. Over thousands of heating cycles, the wire thins, sags, and snaps in half. When the circuit breaks, zero heat is produced.
- OEM Part: Most Samsung electric dryers use the Samsung Heating Element Assembly (OEM Part #DC97-14486A).
- Blown One-Time Thermal Fuse
Mounted directly to the heater duct is a small thermal cutoff fuse. If your exterior dryer exhaust duct is clogged with lint, heat cannot escape. The duct temperature spikes above 260°F, permanently blowing the thermal fuse to prevent a house fire. - Failing Temperature Sensor (Thermistor)
The thermistor is an electronic resistor whose electrical resistance changes with temperature. If the thermistor fails, the control board cannot verify whether the dryer is warm or cold and triggers the tE error code.
STEP-BY-STEP GUIDE: HOW TO TEST AND REPLACE THE HEATING ELEMENT
Tools Required:
- Phillips screwdriver
- 1/4-inch nut driver
- Needle-nose pliers
- Digital multimeter
- Replacement Samsung Heating Element Assembly (Part #DC97-14486A)
Step 1: Unplug the Dryer and Remove the Front Lower Panel
- Unplug the 240V power cord from the wall.
- On most Samsung models, remove the four Phillips screws along the bottom edge of the front lower access panel.
- Pull the lower panel away to reveal the blower housing on the left and the long silver heater duct on the right.
Step 2: Inspect the Thermal Cutoff and High-Limit Thermostat
On the side of the metal heater tube, you will see two small thermostats with wire leads:
- Label or photograph the wires, then pull the female spade connectors off the terminals using needle-nose pliers.
- Turn your multimeter to the lowest Ohms (Resistance) or Continuity setting.
- Touch one probe to each terminal of the thermal fuse.
- If the multimeter beeps or displays near zero ohms (0.0 to 0.5 ohms), the fuse has continuity and is good. If the display shows “OL” (Open Loop) or infinite resistance, the fuse is blown and must be replaced.
Step 3: Test the Heating Element Terminals
Locate the two large, heavy-gauge wire terminals at the very front of the metal heater duct:
- Pull both wire plugs off the element terminals.
- Place the multimeter probes across the two element terminals.
- A functional Samsung heating element will measure between 9.5 and 12.0 ohms of resistance.
- If your meter displays “OL” (infinite resistance), the internal coil has snapped and the heating element is dead.
Step 4: Remove the Heater Duct Assembly
- Remove the mounting screw securing the front of the heater duct to the dryer base.
- Disconnect the remaining thermostat wire harness clips.
- Slide the entire metal heater tube forward and out of the dryer cabinet.
Step 5: Install the New Element and Reassemble
- If replacing the complete assembly, slide the new heater duct into position, ensuring the rear exhaust nozzle seats firmly into the rear drum bulkhead port.
- Secure the mounting screw.
- Reattach all wire connectors to their corresponding thermostat and heater terminals.
- Reinstall the lower access panel, plug the dryer into the 240V receptacle, and start a 10-minute “Timed Dry” cycle on High Heat. You should feel hot air blowing through the exhaust vent within 60 seconds.
CRITICAL MAINTENANCE: CLEAN YOUR EXHAUST DUCT
Heating elements do not burn out on their own—they burn out because restricted airflow causes the heating chamber to run excessively hot. Whenever you replace a heating element, you must inspect and vacuum your flexible exhaust duct and the exterior wall vent hood to clear all lint blockages.
FREQUENTLY ASKED QUESTIONS
Can I replace just the coiled wire instead of the whole assembly?
Yes, restringing coils is possible, but not recommended. Restrung coils often sag and short against the grounded metal housing within months. Replacing the complete heater housing (which includes fresh thermostats) guarantees factory reliability.
Why did my new heating element blow immediately after installation?
If a brand-new heating element burns out during its first cycle, your exterior vent duct is severely clogged, or the heating coil shifted during installation and touched the grounded metal casing, creating a continuous short circuit.
What is the difference between HE and tE on a Samsung dryer?
HE indicates a physical heating failure (the coil or fuse is broken). tE indicates a sensor failure (the thermistor cannot communicate resistance readings to the computer).
