Compatibility & Fitment

  • Designed for a wide range of electric clothes dryers.

When to Replace

  • Primary symptom is the dryer tumbling but producing no heat.
  • The dryer may not start at all if the fuse is part of the main motor circuit.
  • Replace when the original fuse shows no continuity when tested with a multimeter.
  • It is critical to also resolve the underlying overheating issue, such as a clogged vent.

Installation Tips

  • Disconnect the dryer from the electrical outlet before beginning any repair work.
  • The fuse is typically located on the heater box or blower wheel housing.
  • Verify the existing fuse has failed by testing for continuity; a reading of infinity or "OL" confirms it is blown.
  • Before installing the new fuse, thoroughly clean the lint trap, exhaust hose, and external vent to ensure proper airflow and prevent repeat failure.

FAQs

This thermal fuse is commonly used on clothes dryers from Whirlpool, Maytag, Roper, Kenmore, KitchenAid, Crosley, Estate, Inglis, Amana, Admiral, Magic Chef, and Kirkland. Because dryer parts can vary by model and series, the safest match is to confirm your original part number and model number before ordering.
Known cross-reference numbers for this fuse include 3977393, WP3977393, AP3094244, 3399848, AH334299, 279816, 279816VP, PS334299, EAP334299, EA334299, and 2651.
A blown thermal fuse can cause several dryer problems, including the dryer not starting, no heat, weak or inconsistent heat, overheating, or clothes taking too long to dry. On some models, a failed fuse opens the circuit completely and the dryer will appear dead even though power is present.
This fuse is a high-temperature safety device that opens if the dryer overheats. The most common root cause is restricted airflow, such as a clogged lint screen, blocked vent hose, crushed duct, or lint buildup inside the blower housing. It can also fail if the cycling thermostat is not regulating heat correctly or if the dryer is repeatedly run with poor ventilation.
Replacement is usually a straightforward repair for many standard dryers. On most models, you disconnect power, access the rear panel or lower service area, remove the fuse mounting screw, transfer the wires, and reinstall the new fuse. Typical tools are a 1/4-inch nut driver or screwdriver and possibly needle-nose pliers. Many repairs take about 15 to 30 minutes depending on dryer design.
Before replacing the fuse, unplug the dryer and inspect the entire vent path from the lint filter housing to the outside exhaust hood. Clean lint buildup, make sure the duct is not crushed, and verify the blower wheel is turning properly. If airflow problems are not corrected, the new fuse can fail again quickly.
