Ensure safe operation of your dryer with the OEM thermal fuse WP3390719. This one-time safety cut-out is typically mounted on the exhaust duct of the dryer. If the dryer overheats, the fuse opens (is “blown”) to cut off power to prevent damage or fire risk. whirlpoolparts.com+2appliancerepair.homedepot.com+2

Common Symptoms That Indicate Replacement Needed
-
The dryer tumbles but does not heat at all (or heating cuts off very early). appliancerepair.homedepot.com+1
-
You measure the fuse and find it is open (no continuity) when tested with a multimeter.
-
The parts diagram or service manual for your dryer lists WP3390719 (or one of its cross-refs) as the thermal fuse. parts.alliancelaundry.com
-
Other signs of overheating: clogged vent, long drying times, excessive heat escaping, etc — these may have caused the fuse to blow.
Compatibility Notes
-
Fits many residential dryers from Whirlpool, Maytag, Kenmore and affiliated brands that specify WP3390719. parts.alliancelaundry.com+1

Before ordering:
-
Verify your dryer’s model number and serial number (typically on the door opening or rear panel).
-
Make sure the current fuse looks similar in mounting style, rating and location (exhaust duct mounting is common).
-
If the fuse has blown due to a venting issue or other failure (not just a fuse problem), replacing the fuse alone may not permanently fix the issue — ensure venting, heating elements and airflow are inspected.
