🧾 Description
Keep your dryer running safely and efficiently with the WP3979618 Thermal Fuse, a genuine OEM replacement designed and manufactured by Whirlpool.
This safety fuse protects your dryer by shutting off power to the heating element if the appliance overheats. When this fuse blows, your dryer may continue to run but will not produce heat, signaling a failed thermal fuse that must be replaced.
Built to meet Whirlpool’s exact standards, the WP3979618 is made from high-quality, heat-resistant materials that ensure reliable temperature control and long-lasting protection. It’s an essential safeguard that restores safe operation and prevents further component damage.
⚠️ Note: Always disconnect the dryer from power before servicing. A blown fuse cannot be reset—replace it immediately and correct the cause of overheating, such as lint buildup or restricted airflow.
