Samsung & LG Dryer Thermal Fuse Replacement Guide

Interior of Samsung or LG dryer showing thermal fuse mounted near exhaust duct.

Samsung and LG dryers use thermal fuses to prevent overheating and protect internal components.

While access steps may vary slightly between front-load and rear-access designs, the replacement process is similar.

For a complete overview of symptoms, testing, and general replacement steps, see Dryer Thermal Fuse: Complete Guide (Symptoms, Testing & Replacement).

Common Symptoms in Samsung & LG Dryers

A blown thermal fuse may cause:

  • Dryer will not start

  • Dryer powers on but does not heat

  • Dryer shuts down during a cycle

  • Error codes related to overheating (in some models)

Always confirm failure with a multimeter before replacing the fuse.

Where the Thermal Fuse Is Located

In most Samsung and LG electric dryers, the thermal fuse is mounted on:

  • The blower housing

  • The exhaust duct

  • Near the heating element housing

Access typically requires removing the rear panel.

Some front-service models may require removing the top and front panels instead.

Step-by-Step Replacement

  1. Unplug the dryer.

  2. Remove the rear (or front) access panel.

  3. Locate the thermal fuse along the airflow path.

  4. Disconnect the two wire connectors.

  5. Remove the mounting screw(s).

  6. Install the new fuse in the same orientation.

  7. Reconnect the wires securely.

  8. Reassemble the dryer.

Restore power and test operation.

Check Venting Before Finishing

Samsung and LG dryers are sensitive to airflow restrictions.

Before completing the repair, inspect:

  • Lint filter

  • Vent hose

  • Ducting behind the dryer

  • Exterior vent hood

Restricted airflow is the most common reason thermal fuses fail.

Confirm the Correct Replacement

Before purchasing a new fuse, verify:

  • Exact dryer model number

  • Mounting style

  • Temperature rating

  • Connector type

Using an incorrect fuse may cause repeat failures or improper operation.
