Ensure your dryer operates safely and reliably by replacing the thermal fuse with the genuine OEM part WP307473. This thermal fuse acts as a high-limit cut-off device: if the dryer overheats or airflow is severely restricted, it opens the circuit to prevent damage or fire. appliancerepair.homedepot.com+1

Before ordering:
-
Verify your dryer’s model number and serial number (usually inside the door frame or on the rear panel).
-
Compare your current fuse: confirm it’s the same part number or cross-reference list, same mounting style, and proper electrical rating.
-
If your dryer has severe airflow restriction (blocked vent/lint), installing a new fuse alone may not restore optimal performance — the vent system should be inspected.
