Samsung Dryers Not Heating: How to Fix It Yourself
When a Samsung dryer runs but doesn't heat, the most common cause is a blown thermal fuse (a cheap safety part) or a burned-out heating element. Both are affordable and replaceable. The thermal fuse blows when the dryer overheats, usually from a clogged lint vent.
⚠️ Safety First
- Unplug the dryer before working on it.
- If you have a gas dryer, turn off the gas supply line first. If you smell gas at any point, stop and call your gas company.
- The heating element area can retain heat — let the dryer cool for at least 30 minutes before working on it.

Step-by-Step Repair
- 1
Unplug the dryer and pull it away from the wall
Disconnect the power cord. If it's a gas dryer, also turn off the gas valve behind the dryer. You'll need about 2 feet of space behind it to work.
- 2
Check the lint vent first
Disconnect the vent hose from the back of the dryer. Look inside — if it's packed with lint, that's probably why your thermal fuse blew. Clean it out thoroughly. Check the vent all the way to where it exits your house.
- 3
Remove the back panel
Using your nut driver or screwdriver, remove the screws holding the back panel on. Set them aside in a bowl so you don't lose them. Carefully remove the panel.
- 4
Locate the thermal fuse
The thermal fuse is a small, usually white or silver piece about 1 inch long, typically mounted on the blower housing or near the heating element. It has two wires connected to it.
- 5
Test the thermal fuse (if you have a multimeter)
Set your multimeter to continuity mode. Touch one probe to each terminal of the thermal fuse. If it beeps, the fuse is fine. If there's no beep, the fuse is blown and needs to be replaced.
- 6
Replace the thermal fuse or heating element
If the fuse is blown: disconnect the two wires, unscrew the fuse, install the new one, reconnect wires. If the heating element is visibly damaged (broken coils), replace it the same way — disconnect wires, remove mounting screws, swap in the new one.
- 7
Reassemble and test
Put the back panel back on. Reconnect the vent hose. Plug it back in (and turn gas back on if applicable). Run a short cycle with a damp towel to confirm it heats up.
If That Didn't Work
- Clogged lint vent (clean it — this is the #1 cause of dryer problems and house fires).
- A faulty high-limit thermostat can prevent the dryer from heating.
- On gas dryers, the gas valve solenoids may need replacement.
- The cycling thermostat may be faulty.
When to Call a Professional
If you have a gas dryer and aren't comfortable working with gas connections, call a professional. Also call if you've replaced the fuse and element but it still doesn't heat — there may be an electrical issue with the control board ($100–$200 to repair).
