What Does Error Code SYMPTOM‑NOT‑HEATING Mean?

Error SYMPTOM‑NOT‑HEATING on your Samsung Dryer means: The SYMPTOM‑NOT‑HEATING code tells the dryer’s control board that it cannot generate heat. The drum will tumble, but clothes stay damp and the display may flash a warning. The fault usually involves the heating element, thermal fuse, or a temperature sensor.

What You'll Need

🔧 Tools

  • Phillips #2 screwdriver
  • T20 Torx bit
  • Digital multimeter
  • Needle‑nose pliers
  • Vacuum cleaner with hose attachment

🛒 Parts

  • Heating element (part number varies by model)
  • Thermal fuse (often part number D/AE001‑00200A)
  • Temperature sensor (thermistor) kit
  • High‑limit thermostat

How to Fix Error SYMPTOM‑NOT‑HEATING — Step by Step

  1. 1

    Quick Power Reset

    Unplug the dryer or switch off the dedicated breaker for at least 60 seconds. This clears any transient fault memory stored in the control board. Plug the dryer back in and start a short “air‑fluff” cycle. If the error disappears, the problem was a temporary glitch.

  2. 2

    Clean Lint Filter and Vent Path

    Remove the lint screen, discard lint, and wash the screen with warm, soapy water. Rinse, dry, and reinstall. Detach the vent hose, then vacuum the hose and dryer’s exhaust opening to remove any lint buildup.

  3. 3

    Safety First – Disconnect Power

    Before testing any electrical component, ensure the dryer is unplugged and the circuit breaker is off. Use insulated tools and avoid touching live wires.

  4. 4

    Test the Heating Element for Continuity

    Open the dryer’s front or rear panel (refer to your model’s service manual). Disconnect the two power wires from the element. Set the multimeter to the ohms (Ω) setting and touch the probes to the element terminals. A healthy element reads between 10 Ω and 30 Ω. An infinite reading means the element is open and must be replaced.

  5. 5

    Check the Thermal Fuse

    Locate the thermal fuse on the exhaust housing. With power still disconnected, pull the two wires from the fuse and measure continuity. A good fuse will beep or show near‑zero resistance. No beep indicates a blown fuse; replace it with an exact‑fit part.

  6. 6

    Verify the Temperature Sensor (Thermistor)

    The thermistor sits near the heating element. Disconnect its connector and measure resistance at room temperature; most Samsung sensors read about 2 kΩ. Gently heat the sensor with a hair dryer; the resistance should drop below 500 Ω. If the value stays the same, replace the sensor.

  7. 7

    Examine the High‑Limit Thermostat

    Find the round thermostat on the dryer’s exhaust housing. Disconnect its wires and test for continuity. A functional thermostat shows low resistance (under 100 Ω). An open circuit means the thermostat has tripped and needs replacement.

  8. 8

    Inspect Wiring Harnesses and Connectors

    Remove the rear panel and trace the wires from the control board to the heater, fuse, and sensors. Look for cracked insulation, burnt spots, or loose connectors. Reseat any loose plugs and clean corrosion with a small brush.

  9. 9

    Run a Test Cycle

    Reassemble the dryer, plug it back in, and start a timed high‑heat cycle. After a few minutes, feel the exhaust vent; it should be warm (120‑140 °F / 49‑60 °C). Verify that the SYMPTOM‑NOT‑HEATING code no longer appears on the display.

When to Call a Professional

If the error persists after replacing the heating element, thermal fuse, temperature sensor, and thermostat, the fault likely resides in the control board or a hidden wiring issue. Also call a certified technician if you discover burnt wiring, a tripped circuit breaker, or suspect gas‑related components (rare on electric models). Samsung support can be reached at 1‑800‑726‑7864.

Field note: SYMPTOM‑NOT‑HEATING is too much heat / not enough airflow until the vent is proven clear. On Samsung dryers, clean the lint path through the wall cap so you can feel strong exhaust outdoors. Crushed foil hose and a bird nest beat a new heating element. Replace a thermal fuse only after airflow is fixed or it will open again.

What this code is not

  • Not a ‘new heating element first’ code.
  • Not a Wi-Fi or child-lock issue.
  • A new fuse with a still-clogged vent will open again, often on the next load.

The Samsung Dryer error SYMPTOM-NOT-HEATING can be frustrating, especially when you’re in the middle of a laundry cycle. This error code indicates that your dryer is unable to generate heat, causing your clothes to stay damp. The drum will continue to tumble, but the display may flash a warning. In this comprehensive guide, we’ll walk you through the possible causes, troubleshooting steps, and repair options to get your dryer up and running again.

Diagnosing the Source of the Problem

Here are the possible causes of the SYMPTOM-NOT-HEATING error code on your Samsung dryer:

1. Faulty Heating Element

  • Description: The heating element is responsible for producing heat in your dryer. If it’s faulty, the dryer won’t heat up.
  • How to verify: Use a multimeter to test the heating element for continuity. If it shows no continuity, it’s likely faulty.
  • Fix difficulty: Medium
  • Cost: $50-$150 (part number varies by model)

2. Blown Thermal Fuse

  • Description: The thermal fuse is a safety device that blows if the dryer overheats. If it’s blown, the dryer won’t heat.
  • How to verify: Locate the thermal fuse on the exhaust housing and test it for continuity. If it’s blown, replace it.
  • Fix difficulty: Easy
  • Cost: $10-$30 (often part number D/AE001-00200A)

3. Faulty Temperature Sensor (Thermistor)

  • Description: The thermistor monitors the temperature inside the dryer and sends signals to the control board. If it’s faulty, the dryer won’t heat.
  • How to verify: Use a multimeter to test the thermistor for resistance. Compare it to the manufacturer’s specifications.
  • Fix difficulty: Medium
  • Cost: $20-$50 (thermistor kit)

4. High-Limit Thermostat Issue

  • Description: The high-limit thermostat is a safety device that trips if the dryer overheats. If it’s faulty, the dryer won’t heat.
  • How to verify: Locate the round thermostat on the dryer’s exhaust housing and test it for continuity. If it’s faulty, replace it.
  • Fix difficulty: Medium
  • Cost: $20-$50

5. Wiring Harness or Connector Issues

  • Description: Corrosion or damage to the wiring harness or connectors can prevent the dryer from heating.
  • How to verify: Inspect the wiring harness and connectors for damage or corrosion. Clean or replace them as needed.
  • Fix difficulty: Medium
  • Cost: $10-$50

Specific Quirks by Model Number

Some Samsung dryer models are more prone to the SYMPTOM-NOT-HEATING error code than others. Here are some model-specific differences:

  • 2012-2015 models: These models are more likely to experience issues with the heating element.
  • 2016 and later models: These models have an updated heating element design that’s less prone to failure.
