FAQ

This thermal fuse is designed for use in a wide range of dryers manufactured by Whirlpool, Maytag, Roper, Kenmore, KitchenAid, and Kirkland. It is compatible with numerous models, including those in the 110.60012000, 3HLER5437JQ0, and LER6634BW2 series.
This part replaces OEM numbers 3977393 and WP3977393. It also cross-references with 3399848, 279816, 279816VP, AP3094244, AH334299, PS334299, EAP334299, EA334299, and 2651.
If your dryer runs but fails to heat up, or if the dryer does not start at all, a blown thermal fuse is a frequent culprit. If you have a multimeter, you can test the fuse for continuity; if there is no continuity, the fuse has tripped and must be replaced.
The primary cause of a blown thermal fuse is restricted airflow. Before installing a new fuse, it is critical to clean your dryer vent ducting, check the exterior vent hood for blockages, and ensure the lint screen is clean. If the dryer cannot exhaust hot air properly, the internal temperature rises until the fuse trips to prevent a fire hazard.
Replacing the thermal fuse is a standard repair that typically takes 20 to 40 minutes. You will generally need a screwdriver (often a 1/4-inch nut driver) to remove the dryer's back or front panel, depending on your specific model. Always disconnect the power supply to the dryer before beginning any work.
While the fuse itself is the component that trips, it is highly recommended to inspect the heating element and the cycling thermostat for signs of wear or damage. Most importantly, ensure your entire venting system is clear of lint buildup, as this is the root cause of most thermal fuse failures.
