In this guide, we explain why a Samsung dryer may stop heating and walk you through easy and safe troubleshooting steps you can try at home.
Why Is My Samsung Dryer Not Heating?

Common causes include:
- Incorrect dryer settings
- Clogged lint filter or vent
- Power supply issues
- Overheating protection triggered
- Faulty heating components
Quick Fix Summary
| Possible Cause | Difficulty | Recommended Solution |
|---|---|---|

Fix 1: Check Dryer Heat and Cycle Settings
Some dryer cycles use low or no heat.
Make sure:
- The cycle is not set to Air Dry or Cool
- Heat level is set to Medium or High
- Sensor Dry mode is used correctly
Incorrect settings are one of the most common causes of no heat.
Fix 2: Clean the Lint Filter
A clogged lint filter restricts airflow and may prevent heating.
Steps:
- Remove the lint filter
- Clean off lint and debris
- Rinse with warm water if needed
- Let it dry completely
- Reinsert the filter
Clean the filter before every drying cycle.
Fix 3: Inspect the Dryer Vent and Exhaust Hose
Poor airflow can cause the dryer to stop heating for safety reasons.
Check that:
- The vent hose is not crushed or kinked
- The exhaust outlet is clear
- Lint buildup is removed
Restricted airflow may trigger overheating protection.
Fix 4: Check Power Supply and Circuit Breaker
Electric dryers require a proper power supply to heat.
- Make sure the breaker is fully on
- Reset the breaker if needed
- Avoid using extension cords
A dryer may run but not heat if power is incomplete.
Fix 5: Restart the Dryer
A temporary control board glitch may stop heating.
How to restart:
- Turn off the dryer
- Unplug it for 5 minutes
- Plug it back in and start a new cycle
If heat returns, the issue was temporary.
When to Contact Samsung Support
Contact Samsung support if:
- The dryer still does not heat
- You notice burning smells
- The dryer shuts off unexpectedly
Internal components such as heating elements or thermostats may require professional service.
How to Prevent Heating Issues in the Future
- Clean the lint filter regularly
- Keep vents clear
- Do not overload the dryer
- Use recommended drying cycles
- Schedule routine maintenance
