🧾 Description
Ensure precise drying performance and optimal temperature control with the WP3976580 Internal-Bias Thermostat, a genuine OEM replacement manufactured by Whirlpool.
This thermostat regulates the air temperature inside the dryer drum during operation. When it detects the correct temperature, it cycles the heating element off, then back on as needed to maintain efficient and safe drying conditions. If it malfunctions, your dryer may overheat, underheat, or take longer than usual to dry clothes.
Crafted with Whirlpool’s high standards of quality, the WP3976580 provides accurate temperature sensing and dependable cycling performance — helping your dryer run smoothly, safely, and efficiently.
⚠️ Note: Always unplug the dryer before installation. Verify your model number to ensure compatibility before purchase.

🧩 Compatibility Notes
-
Confirm your dryer’s model number (inside door frame or on the back panel) before ordering.
-
For the best results, replace the internal-bias thermostat (WP3976580) together with the high-limit thermostat (WP3976570) and thermal fuse (WP3976569) — these components work in tandem to regulate temperature and prevent overheating.
-
Regularly clean your lint screen and exhaust vent to maintain airflow and prevent premature component failure.
