What to do first: confirm the cycle can produce heat, clean the lint filter and check the accessible exhaust path. Keep thermal protection intact and do not open energized panels; a dryer that smells hot, scorches clothes or trips power needs service.
Scope: Samsung dryers sold in the United States are covered by the linked Samsung workflow; controls and supply arrangements vary by model and country.
Current official check:Samsung’s no-heat troubleshooting page starts with cycle, error and vent checks and sends unresolved no-heat faults to service. USFA fire-safety guidance stresses lint and exhaust-duct maintenance.
Stop for these warning signs
Do not keep running the dryer when you notice:
- burning smell or smoke
- scorched lint
- unusually hot cabinet, cord, plug, or outlet
- sparks or arcing
- repeated breaker trips
- damaged gas line or gas odour
Disconnect power when safe. For suspected gas leakage, follow local emergency guidance and avoid operating electrical switches near the leak.
Step 1: Check the cycle
Air fluff, cool air, delicate, sensor, eco, and low-temperature cycles can behave differently. Test with a small load on a normal heated cycle recommended in the owner manual.
Make sure child lock, delay, or other settings are not confusing the result.
Step 2: Clean the lint filter
Clean the filter before the test and inspect for coating from dryer sheets or residue. Follow Samsung’s cleaning instructions. A filter that looks clear can still have restricted mesh.
Step 3: Inspect airflow safely
Check the accessible exhaust path for crushing, kinks, or an obstructed exterior hood. The duct material and routing should comply with the installation manual and local code.
Do not operate the dryer long-term disconnected from the vent. Vent inspection and cleaning may require a qualified service when the route is concealed, long, or shared.
Step 4: Confirm installation power
For an electric dryer, verify the breaker has not partially tripped and reset it only according to safe electrical practice. A qualified electrician should test the circuit, receptacle, cord, and terminal block when supply is in doubt.
Do not open panels or test live terminals based on a generic video.
Step 5: Record model information and errors
Note:
- full model code
- gas or electric type
- selected cycle
- whether the drum turns
- whether any heat appears briefly
- error code
- vent and filter condition
- recent installation or electrical work
Check Samsung support for the exact model’s diagnostic guidance.
Internal causes need diagnosis
Possible causes include a heater, safety device, sensor, relay, wiring, gas ignition component, or control fault. Symptoms overlap. A technician should confirm the failed part and the reason it failed before replacement.
Separate no heat from poor drying
Run only the model-supported test or cycle described by Samsung. Record whether the drum turns, the selected cycle allows heat, an error appears, clothes become slightly warm, and airflow is strong at the exterior termination. A dryer that heats but needs multiple cycles often points to airflow, loading or moisture-sensing conditions rather than a total heating failure.
Clean the lint filter and inspect the accessible, cooled and disconnected exhaust path for crushing or obvious blockage. Do not run the dryer with the duct removed as a routine indoor test, and do not reach into a moving blower or disassemble the cabinet. The U.S. Fire Administration guidance makes lint-screen and vent maintenance a fire-prevention step, not merely a performance tweak. If the exterior vent cannot be accessed safely, leave that check for a qualified service provider rather than climbing or moving a heavy appliance.
Give Samsung a model-specific evidence packet
Photograph the model/serial label, cycle selection, error display and accessible vent layout. Note fuel type, recent installation or move, whether a breaker tripped, whether other gas appliances work normally, and when the symptom began. Also record load size and whether the symptom occurs on every heat-enabled cycle, because that distinction helps support teams avoid a misleading single-cycle diagnosis. Use Samsung’s reset guidance only when its stated conditions fit; a reset can clear a transient state but does not repair a recurring airflow, supply or component fault.
Stop immediately for smoke, burning odour, scorching, sparking, abnormal gas smell or repeated power trips. Keep the door switch and thermal devices intact; never test live terminals, light a burner manually or assume a generic button combination applies to every model. If safe external checks do not restore heat, Samsung’s official no-heat flow directs the unresolved case to service.
