Samsung dryer not heating
Check cycle settings, household supply and airflow when a Samsung dryer produces no heat.
What this guide covers
Symptoms: No heat / dryer stays cold
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.
These no-heat checks apply when the drum runs. If the panel is on but the drum does not turn, use the Samsung powered-but-not-spinning guide before checking heat. For a dark panel, use the Samsung no-power guide.

How to check without guessing
General manufacturer guidance. Exact-model controls and procedures have not been verified for this guide.
Model recognition does not verify a control sequence, fuel configuration, vent-test procedure or installation detail. Use the rating label and instructions matching the complete model. Do not remove a terminal cover, probe live voltage, alter wiring or loosen a gas connection. An optional vent test is not a universal exact-model procedure.
Check the display first
A displayed error or blinking-light code takes precedence. Record it exactly and use the code entry; do not clear it merely to continue generic checks.
Check lint and visible ducting
Inspect the installed lint filter and only visible, safely accessible transition duct. Do not move the dryer in a way that strains power, gas or vent connections.
Check the home vent path
An optional Samsung vent-blockage test counts only when the exact model supports it and the documented procedure was actually completed. No test, an inaccessible exterior outlet or unknown airflow is Not sure—not a pass or a confirmed blockage.
Troubleshoot the displayed code first
Keep the exact display and model in the brief. The code path precedes generic no-heat work and may require model-specific service.
Confirm the complaint on an applicable heated cycle
Use a heated cycle that is actually present on the controls. Eco or air-only behavior varies by model. If no matching control or safe observation is available, preserve the step as incomplete.
Correct the filter or visible duct restriction
Correct only observed lint or visible duct restriction, restore the filter/duct safely, then make one heated observation. A hidden home-vent condition remains unknown.
The home exhaust path appears restricted
Use this vent-cleaning exit only for an observed weak/blocked exterior path or a supported test that actually failed. Stop using a severely restricted vent; do not diagnose an appliance part.
Samsung recommends service if the dryer still does not heat
Use appliance service only after the dryer remained cold on an applicable heated cycle and the accessible airflow observations were completed or clearly unavailable. Record gaps honestly; do not infer a failed heater or control.

Safe troubleshooting sequence
Start with the observations and external checks that can be verified without opening energized assemblies. The interactive version asks these in order and changes the path based on your answers.
- Check the display firstSamsung says a displayed error code can supersede generic no-heat troubleshooting. Choose Not sure when the fuel type, control setting, exterior airflow, optional-test availability or safe access cannot be verified. Unknown is not a passed check.
- Check lint and visible ductingRestricted airflow is a major cause of poor drying performance. Choose Not sure when the fuel type, control setting, exterior airflow, optional-test availability or safe access cannot be verified. Unknown is not a passed check.
- Check the home vent pathSamsung recommends verifying that the exhaust system is open and within installation limits. Choose Not sure when the fuel type, control setting, exterior airflow, optional-test availability or safe access cannot be verified. Unknown is not a passed check.
What the answers can lead to
Troubleshoot the displayed code first
The displayed code may identify a condition that should be addressed before generic no-heat steps.
Evidence strength: Strong
Confirm the complaint on an applicable heated cycle
A no-heat or Eco/air-only selection can look like a heating failure. Use only a heated cycle available on the actual controls and observe whether the drum becomes warm.
Evidence strength: Strong
Correct the filter or visible duct restriction
The observed restriction can explain slow or ineffective drying.
Evidence strength: Strong
The home exhaust path appears restricted
A failed vent-blockage check or weak exterior airflow points away from an appliance part and toward the exhaust path.
Evidence strength: Strong
Samsung recommends service if the dryer still does not heat
With airflow checks passing and no applicable error-code fix, internal diagnosis is the next step.
Evidence strength: Strong that service is next
When professional diagnosis is the safer next step
A failed vent-blockage check or weak exterior airflow points away from an appliance part and toward the exhaust path. With airflow checks passing and no applicable error-code fix, internal diagnosis is the next step.
Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict's interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
