Speed Queen Dryer Not Heating: Commercial-Grade Thermal Fuse and Element
Quick Answer
Speed Queen dryers use commercial-grade heating components rated for higher cycles than consumer dryers. However, the thermal fuse still blows from blocked vents. Speed Queen's thermal fuse is rated for a higher temperature than consumer brands (300F vs 250F) but still fails when vent restriction causes sustained temperatures above the rating.

Speed Queen's thermal fuse is rated for a higher temperature than consumer brands (300F vs 250F) but still fails when vent restriction causes sustained temperatures above the rating. Speed Queen gas dryers use a more robust igniter but the same diagnosis applies: if igniter glows >90 sec without gas lighting, replace igniter. Speed Queen's 5-year full warranty covers heating element and thermal fuse.
