How to Tell If Your Dryer Thermal Fuse Is Blown

If your dryer suddenly stops heating or won’t run at all, one of the most common causes is a blown thermal fuse.

Signs Your Thermal Fuse Might Be Bad:

  • Dryer won’t start at all
  • Dryer runs but produces no heat
  • Dryer shuts off too quickly

The thermal fuse is a safety device designed to shut the dryer down if it overheats. Once it blows, it cannot be reset — it must be replaced.

Quick Test:

Using a multimeter:

  1. Disconnect power from the dryer
  2. Remove the fuse
  3. Check for continuity
  • No continuity = bad fuse

Important Tip:

If the fuse blew, there’s usually a reason:

  • clogged vent
  • restricted airflow
  • lint buildup

Replacing the fuse without fixing the cause will likely lead to it blowing again.
