FAQs

This fuse replaces OEM part number 3977394 and is compatible with the following cross-reference numbers: 80001, 279548, 695563, 2796769, 279769VP, 3387812, 3389946, 3398671, 2821, 2004, AP3094224, PS334278, and EAP334278.
This thermal fuse is designed for use with Whirlpool and Kenmore dryers.
The most common symptom is a dryer that runs but fails to produce heat, or a dryer that will not start at all. If the dryer stopped mid-cycle and won't turn back on, the fuse has likely blown as a safety precaution. You can confirm this by testing the fuse for continuity using a multimeter; if there is no continuity, the fuse must be replaced.
A thermal fuse is a safety device designed to break the circuit if the dryer overheats. The most common cause is restricted airflow, typically due to a clogged dryer vent, a blocked lint screen, or a buildup of lint inside the dryer cabinet. Always ensure your venting system is clear before installing a new fuse to prevent it from blowing again immediately.
Installation is generally straightforward and can be completed in about 20 to 30 minutes. You will typically need a screwdriver (usually a 1/4-inch nut driver) to remove the back or front panel of the dryer to access the blower housing where the fuse is mounted. Always disconnect the power supply to the dryer before beginning any repairs.
Yes. Before installing the replacement, inspect your entire exhaust vent system from the back of the dryer to the outside of your home to ensure there are no blockages. Additionally, check that the blower wheel is not obstructed and that the dryer's internal lint trap is clean. Replacing the fuse without addressing a restricted vent will likely cause the new fuse to fail as well.
